1. Introducing Network Monitor

1.1. Product Overview

ActiveXperts Network Monitor is a network and server monitoring tool to allow administrators to monitor the network for failures and irregularities automatically. It can monitor all aspects of your LAN- and WAN servers, workstations and IP devices. For years, ICT administrators, network operators and helpdesk employees have relied upon the power, flexibility and reliability of ActiveXperts Network Monitor.

The mission of the product is to maximize the reliability of your production servers and applications through the automatic detection and correction of problems and issues. The product runs as a service on a Windows 2019/Windows 2016/Windows 2012(R2)/2008(R2)/10/8/7/ platform. There's a 64-bit edition and a 32-bit edition of the software.

When a problem is detected, you're immediately notified by e-mail, SMS, pager, SNMP trap or network message. If possible, the network monitor tool will try to correct the problem.

The two main programs of ActiveXperts Network Monitor are:

  • ActiveXperts Network Monitor Service - the Engine, running as a Windows background service;
  • ActiveXperts Network Monitor Manager - a Windows forms application used to configure the software and view the results.

The ActiveXperts Network Monitor Service is the Engine of the product; it runs in the background as a Windows Service, without a user interface. It continuously monitors servers, workstations and IP devices in your LAN/WAN for availability. This Engine is also responsible for notifying, triggering actions, recovery and logging. There's no agent software required on the servers being monitored; the monitoring service uses protocols and application layers of the Operating System to do its job.

The ActiveXperts Network Monitor Manager application is used to view the results and to make changes to the configuration. This Manager application allows you to visually monitor the network from any desktop PC.

The Manager application can be installed on any Windows 7 or higher workstation, or any Windows 2008 or higher server, and has different authority levels. You can for instance restrict your help desk staff to only see monitoring results, and allowing network operators to make changes to the configuration.

Add new functionality to the product by writing your own VBScript or PowerShell routines. This way, you can monitor almost every piece of hardware, network protocol, software, and so on. Also, VBScript allows you to include techniques like WMI (Windows Management Interface) and ADSI (Active Directory Service Interfaces).

1.4. Custom Checks

ActiveXperts Network Monitor allows you to extend the set of built-in check routines by writing your own check routines.
ActiveXperts supports PowerShell (Windows), VBScript (Windows), Remote Command (Windows) and SSH (Linux/Unix) for custom scripting.

PowerShell and VBScript are defacto standards for scripting in Windows. Both are popular because of its wide acceptance and its support for ActiveX technologies. PowerShell has full support for .NET frameworks. ActiveXperts ships with a large collection of PowerShell scripts and VBScript scripts. You can use these script directly, or make modifications to it to meet your requirements.

SSH is a defacto secure standard for remote shell execution. RSH is the less-popular, non-secure equivalent. ActiveXperts ships with a large collection of SSH shell scripts. You can use these script directly, or make modifications to it to meet your requirements.

1.5. Errors, Failures and Recovery

A Monitoring Check has a Status, which is the result of the check. These are the possible Status values:

  • OK
  • Error
  • Failure
  • Maintenance
  • Failure by Dependee;
  • On Hold
  • Not Monitored
  • Uncertain
'OK' Status

The check meets all the conditions. The corresponding computer/device is working fine.

'Error' Status

If a check doesn't match the conditions as defined by the system operator for a while, it's considered as an 'Error'. Think of an ICMP check for server 'www.activexperts.com'. Sometimes, the ping will fail (for instance once a week), because a router on the internet has a hick-up. You don't want to ring all bells and whistles in this situation. So, the check is in the Error status. But when this error happens a few a times in a row (configurable), it's considered as a 'Failure'.

'Failure' Status

A 'Failure' is the occurrence of one or more 'Errors' in a row. The number of errors (let's say x, the so called threshold) is configurable. After x errors in a row, it is called a 'Failure'. Only on failure, notifications are sent out and actions are triggered. For instance, with an 'ICMP Ping' check that has the threshold set to 5, a failure notification will be sent after 5 consecutive error pings.

'Maintenance' Status

If the result of a check is not successful during a Maintenance period, it won't be considered as a regular 'Error' or 'Failure'. Instead, the status will be: 'Maintenance'. This indicates that the negative result is caused by maintenance on servers, devices or network. No notifications will be sent and no actions will be triggered.

'Failure by Dependee' Status

If a check fails as a result of another failed server, and there is a dependency relation between these checks, it will not be reported as a regular failure; no notifications will be sent and no actions will be performed. Imagine you have a server 'S1' on a remote location, and there's router 'R' connecting your LAN with the remote location, and you have ICMP checks for both 'S1' and 'R'. By making 'S1' dependent of 'R', a failure of 'R' will only result in notifications for 'R', not for 'S'. Dependencies can be configured from the Dependency command in the Tools menu.

'On Hold' Status

You can put a check 'On Hold'. This means, that the check will not be monitored as long as the check remains 'On Hold'.

'Not Monitored' Status

If a check cannot be processed by the engine, the status is set to 'Not Monitored'. Think of a monitoring check based on the SNMP check, but the Network Monitor Engine doesn't have the SNMP service installed. It cannot process the check and will set the result to 'Not Monitored'.

'Uncertain' Status

If the result of a check cannot be determined by the Engine, the status is set to 'Uncertain'. Think of a Disk Space monitoring check, monitoring free disk space on a file server. If the file server becomes totally unavailable, the Network Monitor Engine cannot determine the Disk Space. In this situation, the result is set to 'Uncertain'.

Note: You can change the way Network Monitor handles 'Uncertain' events. By default, all checks which results cannot be determined are set to 'Uncertain'. You can configure not to use the 'Uncertain' status, and set each undetermined result to either 'Success' or 'Error'.

About Recovery

If a server leaves the 'Failure' status and enters the 'Success' status, we're talking about 'Recovery'. 'Recovery' itself is not a status; however, in this situation, Notifications can be sent and Actions can be triggered. This can be useful for Administrators and Operators, so they know that an Action was successful.

2. Installing Network Monitor

2.1. Software Components

The central monitoring service runs on a (dedicated) Windows Server (or Workstation) platform, 64-bit or 32-bit; it monitors computers/devices in your LAN, WAN or even outside your enterprise. No additional software is required on the monitored servers.

The graphical 'ActiveXperts Network Monitor Manager' application is running on the operators desktop PC; it connects to the central monitoring service, and allows you to make changes to the configurations, and view the results.

ActiveXperts Network Monitor Service

The 'ActiveXperts Network Monitor Service' is also called the 'Engine'. It is a Windows Service (AxNmSvc.exe), and is the actual monitoring program. It runs in the background without desktop interaction. It monitors the computers/devices in your LAN/WAN for availability at specific time intervals. This service is multi-threading, allowing the service to monitor many computers/devices simultaneously.

The service is responsible for notification, actions, recovery, logging, and so on.

Note: ActiveXperts Network Monitor doesn't require agent software on the servers you monitor; the service only uses protocols and application layers of the Operating System to do its job.

ActiveXperts Network Monitor Manager

The 'ActiveXperts Network Monitor Manager' application (AxsNmApp.exe) is used to view the status of your network and to make changes to the configuration. You can install the Manager application on any workstation/server in your LAN/WAN.

The Manager application can be installed on any Windows 7 or higher workstation, or any Windows 2008 or higher server.

ActiveXperts Report Generator

The 'ActiveXperts Network Monitor Report Generator' is used to create new reports. There are two versions: a graphical version (AxRgGui.exe) to create eports using a wizard, and a command line version (AxRgCmd.exe) to create reports from the command line or from the Task Scheduler.

Reports are based on a Report Definition file (.rep), which describes the properties of a report (like: filters, sorting, layout, output file and more).

ActiveXperts Graph

The 'ActiveXperts Network Monitor Graph' program (AxGraph.exe) is used to create statistical graphs.

ActiveXperts Reports and Graphs Configuration Tool

The ActiveXperts Reports and Graphs Configuration Tool (AxRgTpl.exe) is used to manage Reports and Graphs.

ActiveXperts Web Access

ActiveXperts Web Access is a comprehensive web interface, designed for mobile devices, tablets and PC's. It allows users you to see those parts of the Network Monitor configuration that they have access to.

ActiveXperts Web Access Configuration Tool

The ActiveXperts Network Monitor Web Access Configuration Tool (AxWeb20Cfg.exe) is used to configure ActiveXperts Web Access.

Installation Files

The full ActiveXperts Network Monitor installation package is available from the ActiveXperts Download Site. There are two setup files: AxMonitorSetup64.exe (for 64-bit operating systems) and AxMonitorSetup32.exe (for 32-bit operating systems).

After you download the file from the internet, you start the setup procedure on the server that you assigned as the monitoring server. This server doesn't have to be a dedicated server. The installation will install the monitoring service, the Manager application and several tools and utilities.

2.2. Install Network Monitor

It's recommended to use a server platform for the ActiveXperts Network Monitor Service, because server platforms support more simultaneous network connections Server platforms are optimized for application services.

Usually, the installation is done only once, on the server that is dedicated as the monitoring server. A wizard will take you through the installation.

Upgrading ActiveXperts Network Monitor from a previous version

Upgrade of ActiveXperts Network Monitor requires un-installation first, followed by a new installation of the software. All configuration files will be preserved during un-installation. However, it is recommended to export the configuration to a save place, before you uninstall the product.

Upgrade - Step-by-Step

Step 1 - Backup the Configuration (Recommended, not required)

In the Manager application, choose Backup Configuration from the File menu, and export the configuration to a save place.

Step 2 - Uninstall old version

Uninstall the old ActiveXperts Network Monitor version using from the Programs and Features applet from the Windows Control Panel
NOTE: The configuration data will be preserved after uninstall.

Step 3 - Run the Setup application

Launch the Setup application (AxMonitorSetup64.exe for 64-bit operating systems, or AxMonitorSetup32.exe for 32-bit operating systems). It will detect a previous installation of ActiveXperts Network Monitor. It will ask to press OK to uninstall the current installation of ActiveXperts Network Monitor. After pressing OK, the software will be uninstalled. The previous configuration files will be preserved.

Step 4 - Install ActiveXperts Network Monitor

Launch the Setup application (AxMonitorSetup64.exe or AxMonitorSetup32.exe) again. Follow the steps described below.

Step 5 - Restore a configuration

After the installation has completed, you can restore any Network Monitor configuration file, no matter what version of Network Monitor was used to create it.

Installing ActiveXperts Network Monitor

Before you start the installation, you must assign one of your Windows servers in your network as the ActiveXperts Network Monitor Server. This machine will host the Network Monitor Engine (service).

Download the installation file (AxMonitorSetup64.exe or AxMonitorSetup32.exe) from the internet and run this program on the server that you assigned as the monitor server.

Installation - Step-by-Step

Step 1 - Welcome Message

This is where the installation begins.

Step 2 - Setup Type

Choose "Network monitor Engine + Management Console" if you want to install the Network Monitor service. The first installation should always be this type of installation. After the first installation, you can run a "Management Console" installation on network workstations to allow users to view the monitoring results of Network Monitor, or to make changes to the configuration.

Step 3 - Licensing information

Here, you can enter you License code. If you enter 'FREE' as the license code, you will be able to use the software for free with a limited number of checks.

Step 4 - Choose Destination Folder

Choose a destination folder. Setup will copy the service, the Manager application, the Manager Setup files and other components to this location. Please make sure to have approximately 50 megabytes available.

Step 5 - Select Program Folder

Specify a name for the Program folder.

Step 6 - Service Account

The 'ActiveXperts Network Monitor Service' (the Engine) must be configured to run under a Windows account. This can be the built-in System user, but it is recommended to provide a Domain Admin or Enterprise Admin account, because it is likely that ActiveXperts Network Monitor needs access to servers in the domain with administrative rights to do its job. However, it's not mandatory to provide a Domain/Enterprise Admin account; for every monitoring check, alternate credentials can be provided.

2.3. Install Management Console

About Installing the Management Console

You can use the Management Console (the 'ActiveXperts Network Monitor Manager') on any workstation in your domain. Use this ActiveXperts Network Monitor Manager application to:

  • Manage the configuration;
  • View the monitoring results;
  • Run Reports and Graphs.

The Manager application is already installed by default on the server where the ActiveXperts Network Monitor service runs. So, there's no need to run ActiveXperts Network Monitor Manager installation on the server.

By default, installing ActiveXperts Network Monitor Manager applications on remote computers is prevented for security reasons. To allow the installation of the Manager application on other computer, a share must be created. This share will be used by the remote Manager application to communicate with the Network Monitor Engine.

To define the Share, use the 'ActiveXperts Network Monitor Manager' application and do the following:

  • Choose Options from the Tools menu, and select the Remote Manager tab;
  • A Wizard appears, which will guide you through the steps of creating the Share.

Once you have created the share, you're ready to install the ActiveXperts Network Monitor Manager on remote PC's.

Simply run the AxMonitorSetup64.exe or AxMonitorSetup32.exe setup program (same installation as used for the server installation) on the workstation, and choose 'Install Management Console only'. The Setup program will now prompt for a share. Enter the share (UNC format) of the central ActiveXperts Network Monitor directory.

To be able to run the Network Monitor Manager application on workstations, Users (operators) need Change (RWX) permissions on the files in the shared directory.

To allow/prevent users in the network from installing/running the Network Monitor Manager, simply use NTFS permissions or Share Permissions. The easiest is to use Share Permissions: simply add/remove RWX permissions to allow/prevent Users or Groups at Share level.

Installation Step-by-Step

Step 1 - Welcome Message

This is where the installation begins.

Step 2 - Setup Type

Choose 'Install Management Console only'. It will install the Network Monitor Manager, the Report Generator and utilities on the workstation PC.

Step 3 - Location of the central Network Monitor server

You're prompted for the location of the central Network Monitor Server share. Enter the share, as discussed in the previous topic.

Step 4 - Choose Destination Folder

Choose a destination folder. Setup will copy all program files to this location. Please be sure to have approximately 5MB available, depending on the type of installation.

Step 5 - Select Program Folder

Specify a name for the Program folder.

Note: If the central monitoring server runs a 64-bit edition of ActiveXperts Network Monitor, it is possible to install the 32-bit edition of the ActiveXperts Network Monitor on the Management console and connect to the 64-bit server.

3. Configuring Network Monitor

3.1. Introduction

The ActiveXperts Network Monitor configuration consists of checks ad global sttings, and is stored in an Microsoft SQL Server Compact Database named Config.sdf. In a default installation, it is located in folder:
C:\ProgramData\ActiveXperts\Network Monitor\Configuration\

Use the ActiveXperts Network Monitor Manager application to make configuration changes, to view real-time monitoring information, and to analyze results. The Manager application can be launched from any 64-bit or 32-bit Windows platform, or from the machine where the service is running on.

You don't need to restart the 'ActiveXperts Network Monitor Service' every time you make changes to the configuration. The service will detect configuration changes as they are made, and will reload the configuration.

The ActiveXperts Network Monitor configuration can be imported, exported and cleared at any time. By using the Backup command, the configuration can be backed up to a save location. By using Restore command, a configuration can be loaded and set as the current configuration. By using the Clear command, you can clear your current configuration and start from scratch. None of the above commands need a restart of the ActiveXperts Network Monitor Service.

Note: The Config.sdf configuration file is an MS SQL Server Compact database.
You can open this file using either Microsoft SQL Server Management Studio (ships with Microsoft SQL Server 2008 and higher), or using Microsoft Visual Studio 2010 or higher.

3.2. Manager Application

To launch the 'ActiveXperts Network Monitor Manager', click Start, point to the ActiveXperts Software folder, point to the Network Monitor folder and click on the Network Monitor Manager icon.

Views

The 'ActiveXperts Network Monitor Manager' application window is divided into three views:

  • Folder View (left view) - Checks can be grouped in logical containers called Folders;
  • Checks View (right view) - list of checks that are organized in the selected folder. The checks in the subfolder(s) of the selected folder are also displayed;
  • Activity View (bottom view) - shows the activity of the 'ActiveXperts Network Monitor Service'.
Permissions

You can assign permissions to users by the use of Operator Roles.

Status Information and Icons

In the server view, an icon precedes every server entry. Here's a list of all possible status values (with corresponding icons) and their meanings:

  • OK - The check meets all the conditions. The corresponding server/device is working fine.
  • Error - If a check doesn't meet the conditions as defined by the system operator for a while, it's considered as 'Error'. For instance, when you configure an ICMP check for web server 'www.activexperts.com', a ping may fail for instance once a day, for example because a router on the internet has a hick-up. You don't want ring all bells and whistles in this situation, because the problem has nothing to do with the actual server. So, the check is in the Error status. Only when the error happens a couple a times in a row, the status is set to Failure.
  • Failure - A Failure is the occurrence of 1 or more errors in a row. This error threshold is configurable. Only when the error happens x times in a row, the status is set to Failure. Only then, notifications are sent out and actions are taken. For instance, when you configure an ICMP check, you should configure to let the check fail only after a couple of errors in a row, let's say 5. So, only when 5 errors occur in a row, the result of the check will be: Failure. Only then, Administrators and Operators will be notified of this failure event.
  • Maintenance - If the result of a check is not successful during Maintenance hours, it won't be considered as a regular 'Error' or 'Failure'. The result will be: 'Maintenance', to indicate that the negative result is due to the maintenance on computers/devices. No notifications will be sent and no actions will be triggered.
  • Failure by Dependee - When a server fails (after a number of errors in a row) as a result of another failed server, and there is a dependency relation between them, it won't be considered as a regular failure; no notifications will be sent and no actions will be taken. Suppose you have a server 'S1' on a remote location, and there's router 'R' connecting your LAN with the remote location, and you have ICMP checks for both 'S1' and 'R'. You should make 'S1' dependent of 'R'. In that scenario, when 'R' fails, you won't get actions/notifications from 'S1'.
  • On Hold - You can put a check 'On Hold', so it won't be processed by the Network Monitor Engine.
  • Not Monitored - Initial status of a check. When the Network Monitor service has just been started, all checks will have status 'Not Monitored'.
  • Uncertain - If the result of check cannot be determined by the Engine, the status is set to 'Uncertain'. Think of a Disk Space check, monitoring free disk space on a File Server. If the File Server becomes unavailable (for instance because it has completely crashed), the Network Monitor Engine cannot determine the Disk Space. In this situation, the status will be set to 'Uncertain'.

3.3. Quick Configuration Wizard

The first time you start the ActiveXperts Network Monitor Manager application, the Quick Configuration Wizard pops up to collect some basic information, like: your SMTP e-mail server, your e-mail address, and so on. The Quick Configuration Wizard also adds some sample monitoring checks to your configuration.

3.4. Backup, Restore Configuration

Restore configuration settings

To import a previously saved configuration, use the Restore function. Note that the current configuration will be overwritten.

To import a configuration:

  • On the File menu, choose Restore Configuration;
  • Select the version of the import configuration file, and click Next;
  • In the File name box, enter a name of a previously exported configuration file;
  • Click Finish to finish the import.

Note: It is possible to Restore a configuration file that was created on another computer.

Backup configuration settings

It's a good practice to make a backup after major configuration changes. The 'Backup Configuration' function exports all of the configuration settings. This means: all global configuration settings (like mail server, default scan time, etc.) as well as all monitoring checks.

To backup a configuration:

  • On the File menu, choose Backup Configuration;
  • In the File name box, enter a name for the new configuration file;
  • Click Save.

Note: The Auto Backup feature automatically backups the configuration periodically. Auto Backup can be configured from the Auto Backup tab of the Options dialog.

New configuration

The New Configuration function clears the existing configuration and creates a new one. The 'ActiveXperts Network Monitor Manager' will ask you to save the current configuration before you clear it.

To create a new configuration:

  • On the File menu, click New Configuration;
  • The program will ask if you want to export the current configuration;
  • After the optional export, it asks you if you're sure to create a new configuration. Press Yes.

3.5. Manage Folders

In ActiveXperts Network Monitor, all checks are organized in folders. Folders are used to organize/group checks.

Add new Folder

To add a new folder:

  • From the Monitor menu, choose New Folder;
  • In the Name field, type the name of the new folder.
Rename Folder

To rename a folder:

  • Select the Folder you want to rename;
  • Choose Properties from the Monitor menu;
  • Type a new name for the folder.
Delete Folder

To delete a folder:

  • Select the Folder you want to delete;
  • Choose Delete from the Monitor menu. When you delete a folder, all check routines and sub-folders in the folder tree will also be deleted.

3.6. Configuring Monitoring Checks

To add a new monitoring check, click New Monitoring Check on the toolbar. To configure an existing monitoring check, double click on the particular check entry in the Manager application, or right-click on the selected check and choose 'Properties'.

Most important configuration items of a Monitoring Check are:

  • Check What - the type of check that is performed on a specific network device, server or workstation;
  • Display Name - the name of the check to be displayed by the Manager application. The display name is also used in log files and reports to refer to this Monitoring Check. The display name can be any user friendly name.
  • Check every / Schedule this Check - specifies how frequent a check will be scanned. You can set it to scan it at a specific date and time, or to scan it frequently with a specific interval.
  • Check fails after x errors in a row - specifies the number of consecutive errors that must occur before a check will be considered as 'Failed'; by default, a check will be considered as 'Failed' after 3 consecutive errors. This option only applies to a check that is not scheduled.

The configuration of checks is discussed in detail in Chapter: Managing Checks.

3.7. Options

Options are global properties, used by all Checks. You can configure these options from the Tools menu, by selecting the Options item.

Logging

See topic: Application Logging

Defaults

'Defaults' apply to new Monitoring Checks. Default values can be defined in the Options dialog:

  • On the Tools menu, click Options;
  • Select the Defaults tab.

The following default values can be configured per check-type:

  • Check every x seconds/minutes/hours/days - specifies how often a monitoring check routine will be scan for a new monitoring check; Initial default value: 30 seconds;
  • Check fails after x errors in a row (error threshold) - specifies the number of consecutive errors that must occur before a new monitoring check will be considered as 'Failed'; Initial default value: 3.

Default values only apply to new checks; they do not affect existing monitoring checks. However, you can apply the default values to all monitoring checks by pressing the Copy/Paste Special from the Edit menu.

Server Credentials

By default, Network Monitor uses the Service Account credentials to monitor remote Windows servers. However, if these credentials do not have administrative permissions on a remote Windows server (for instance because the remote machine is member of another domain, or because the server is a standalone server) you can specify alternate credentials. These alternate credentials are administrated globally, and can be used in any Windows check.

Besides Windows password, you also need to store all Linux, WMware, Citrix Xen and VERDE credentials here.

Performance

See topic: Configuring Threads".

Maintenance

To avoid notifications and actions during maintenance hours, you can configure maintenance schedules. All failures that happen during these schedules won't be notified, and no actions will be triggered.

The maintenance schedules can be configured as Every Day of the Week, or as On This Date.

To configure maintenance schedules:

  • On the Tools menu, click Options and select the Maintenance tab; here, you see the list of configured schedules. You can define multiple schedules;
  • To add a new schedule, choose either Day of Week or This Date.
  • In case of 'This Date', provide start date and time, and provide the number of hours the computer and devices will be unavailable;
  • In case of 'Day of Week', provide the days of the week that the computers and devices will be unavailable; also provide a start time, and provide the number of hours the servers will be unavailable.
  • Press the Add button to add the new schedule to the Maintenance Schedules list.

By default, the maintenance schedules are inherited by all Monitoring Checks; however, you can configure maintenance schedules for each check individually in the 'Advanced' tab of the Monitoring Check properties. Let's say a company has maintenance on every Friday at 11:00 pm for nearly all servers (use the global maintenance schedules for that). But for one server (server 'A'), maintenance is scheduled on Saturday at 09:00 am. Configure individual maintenance schedules for server 'A'.

Auto Backup

The 'ActiveXperts Network Monitor Service' can make a regular backup for you, to a save location. It is recommended to choose a destination folder for your backup that is part of your regular backup procedure.

All program data is located in the programs data folder. In a default installation, it is located in folder:
C:\ProgramData\ActiveXperts\Network Monitor\

With Auto-Backup, you can specify which items to backup automatically to a safe location.

Configure the following itmens for your Backup Location and Schedule:

  • Destination Folder - Folder that will store your backup files.
  • Backup Every - Configure the days and time when the Backup should run.

Configure What to Backup

  • Configuration File - Backup the Config.sdf configuration file;
  • Log Files - Backup the Logs\Log.txt and/or Logs\Log.sdf application log file(s);
  • Statistical Database - Backup the Stats\Stats.sdf Statistical Database. The option is disabled in case you migrated your Statisitcal Database to MS SQL Server or MySQL server.
  • Scripts - Backup the (custom) scripts in the Scripts folder;
  • Report Definition Files - Backup the Report Definition Files and associates XSL stylesheets in the Report Definitions folder;
  • WebView - Backup the WebView files in the Web folder;
Operators and Roles

See topic: Operators and Roles".

Date and Time

Network Monitor does not use Windows' Date/Time settings for displaying information, because results can be viewed by non-Windows users (Web interface, reports, etc.). Therefore, you can set Date/Time settings; these settings are stored in the configuration database, and will be used by all Manager applications, Web Views, Reports, etc..

To configure Date/Time settings:

  • On the Tools menu, click Options and select the Date and Time tab;
  • Select your preferred Time format and Date format.

4. Managing Checks

4.1. Adding a New Check

To add a new Monitoring Check:

  • On the Monitor menu, click Create New Check;
  • In the Check What drop-down box, select the type of check. In the next chapter, Monitoring Checks are described in more detail;
  • In the Display Name box, edit a custom display name; this name will also be used in the log files and reports;
  • In the Check every field, specify how often a check should run. By default, a check will be monitored once every 30 seconds. This default can be changed from the Options dialog in the Tools Menu. To use a scheduled check instead of running it at specific intervals, use the 'Schedule this Check' option (see below) instead of the 'Check every' option;
  • In the Check fails after field, specify the number of consecutive errors that must occur before a check will be considered as Failed; by default, a check will be considered as Failed after 3 consecutive errors;
  • In the Schedule this Check fields, you can define at what times the check should run.

4.2. Copy/Paste a Check

To copy an existing Monitoring Check:

  • On the Edit menu, click Copy.

To paste a Monitoring Check:

  • On the Edit menu, click Paste.

You can copy/paste multiple checks at the same time. There's the option to change the hostname (or IP addresses) during the Paste operation, so you can apply a set of pre-defined checks to a new server, or even multiple servers.

NOTE: Copy/Paste is a powerful command in ActiveXperts Network Monitor. You can define checks for a new server in just a single operation, due to the ability to change the hostname (or IP address) during Paste. You can even Paste to a list of new hosts!

4.3. Copy/Paste Properties

To copy the properties of an existing Monitoring Check:

  • On the Edit menu, click Copy.

To paste properties:

  • Select one or more checks to paste the properties to (or even select a Folder);
  • On the Edit menu, click Paste Properties.

You can apply the following properties to other checks:

  • Check Frequency Settings;
  • Alert Notification Settings;
  • Alert Action Settings;
  • Advanced Settings.

4.4. Deleting a Check

To delete an existing Monitoring Check:

  • On the Monitor menu, click Delete;

Confirm that you really want to remove the server from the configuration.

4.5. Editing a Check

The Monitoring Check dialog will pop up. This dialog contains 4 tabs:

  • Check Properties;
  • Alert Notifications - E-mail, SMS, Pager, SNMP Trap and Network/NetBIOS alert notifications;
  • Alert Actions - Run batch file, exe-file or VBScript programs; restart service(s) or reboot server;
  • Advanced Properties - Configure Notification Frequency (re-notifications), Action Frequency (re-run programs), Maintenance hours and Dependencies.
Check Properties

Select the Check Properties tab, and configure the following fields:

  • Check What - select the type of check, for instance: ICMP;
  • In the Display Name box, edit a custom display name; this name will also be used in the log files and reports;
  • In the Check every field, specify how often a check should run. By default, a check will be monitored once every 30 seconds. This default can be changed from the Options dialog in the Tools Menu. To use a scheduled check instead of running it at specific intervals, use the 'Schedule this Check' option (see below) instead of the 'Check every' option;
  • In the Check fails after field, specify the number of consecutive errors that must occur before a check will be considered as Failed; by default, a check will be considered as Failed after 3 consecutive errors;
  • In the Schedule this Check fields, you can define at what times the check should run.
Notifications Properties

Select the Alert Notifications tab, and configure the following fields:

  • E-mail: Alert Notification (Failure) - If the check fails, send an e-mail notification to the selected recipients. The recipients are either defined in the global Address Book, or configured for this particular check only;
  • E-mail: Recovery Notification (Success) - If the check changes from 'Failure' to 'Success', send an e-mail notification to the selected recipients;
  • SMS: Alert Notification (Failure) - If the check fails, send an SMS notification to the selected recipients;
  • SMS: Recovery Notification (Success) - If computer /device turns from offline to online, send an SMS notification to the selected recipients;
  • Pager: Alert Notification (Failure)s - If the check fails, send an SMS notification to the selected recipients;
  • Pager: Recovery Notification (Success) - If computer /device turns from offline to online, send an SMS notification to the selected recipients;
  • SNMP Trap: Alert Notification (Failure) - If the check fails, send an SNMP Trap notification to the selected recipients;
  • SNMP Trap: Recovery Notification (Success) - If computer /device turns from offline to online, send an SNMP Trap notification to an SNMP network management system;
  • Network: Alert Notification (Failure) - If the check fails, send a network notification to the selected recipients;
  • Network: Recovery Notification (Success) - If computer /device turns from offline to online, send a network notification to the selected recipients.

For all of the above items (except SNMP Traps), you can select recipient groups from the global Address Book.

If you want to use different recipients (or traps) for a particular Monitoring Check, press the '.' button next to the corresponding item.

Actions Properties

You can define an action for each particular check. Actions are triggered when a check fails, or when a check recovers from a failure. There are no global settings for Actions; all settings are made in the properties of the monitoring check.

There are 3 different types of actions:

  • Restart service
    After a failure, it's possible to restart a service. For instance, if you can't reach an IIS web server in your LAN, it may be a good idea to restart the W3SVC service. You can use either the short service name (for instance W3SVC) or the long service name (for instance: World Wide Web Publishing Service). To restart multiple services, enter all services separated by a semicolon (';'), for instance: alerter;browser;
  • Reboot computer
    In some situations, it may be useful to reboot a machine to try to recover from a failure;
  • Run Program You can configure to run a program after a failure has occurred. ActiveXperts Network Monitor supports three different types of programs:

    • Executable files;
    • Batch programs;
    • PowerShell programs;
    • VBScript programs.

You can pass parameters to these programs on the command line. You can also use Notification Variables as parameters, as described in Appx E. Notification Variables.

To configure Alert Actions, select the Alert Actions tab, and configure the following fields:

  • Run Program (.exe, .cmd, .bat) on Failure - If server/device goes offline, run the specified Win32 executable or batch file on the ActiveXperts Network Monitor server;
  • Run Program (.exe, .cmd, .bat) on Recovery from Failure - If server/device turns from offline to online, run the specified Win32 executable or batch file on the ActiveXperts Network Monitor server;
  • Run Program (.vbs) on Failure - If server/device goes offline, run the specified Visual Basic script on the ActiveXperts Network Monitor server;
  • Run Program (.vbs) on Recovery from Failure - If server turns from offline to online, run the specified Visual Basic script on the ActiveXperts Network Monitor server.
  • Run Program (.ps1) on Failure - If server/device goes offline, run the specified PowerShell script on the ActiveXperts Network Monitor server;
  • Run Program (.ps1) on Recovery from Failure - If server turns from offline to online, run the specified PowerShell script on the ActiveXperts Network Monitor server.
  • No reboot/restart after failure - No reboot or restart of a service when failure occurs;
  • After failure, reboot computer - Upon failure, reboot a particular server;
  • After failure, restart service(s) - Upon failure, restart a service on a particular server. You can restart multiple services by providing a list of services. A list of services should contain individual services, separated by the ';' character.

To restart a service or reboot a computer, the 'ActiveXperts Network Monitor Service' credentials are used by default (i.e. the credentials used to start the ActiveXperts Network Monitor service, see also the "Services" applet in the "Administrative Tools" folder). However, if a server is in a different domain or forest, and there is no trust, you may need to pass different credentials to restart or reboot.

To do so, press the Credentials button and select an entry from the Alternate Credentials list. Alternate credentials are administrated globally.

Advanced

Select the Advanced tab to configure the following items:

  • Maintenance Plan for this Check - Select your Maintenance Plan.
  • Graph - Enable or disable graphing for this check. By default, graphing is disabled for new checks to ensure maximum performance of the Statistical Database. When Graphing is enabled, you can specify how frequent the data should be written to the Statistical Database (default: once every 5 minutes);
  • Result of this Check - This option allows you to invert the result of a check, where Success will be turned into Failure and vica versa. This option also allows you to map Uncertain results into either Success or Error;
  • Notification and Action Frequency - This only applies to Failed checks. By default, notifications are sent only once after failure. If you prefer repetitive notifications, select the Notify every radio button and enter the notification frequency. If you prefer repetitive actions, select the Trigger every radio button and enter the frequency;
  • Dependencies - Read-only view of the dependencies for this check;
  • Check ID - Each check has a unique ID. This ID is the key in the [Nodes] table of the configuration database (Config.sdf)

4.6. Monitoring servers in same domain

The ActiveXperts Network Monitor engine runs as a service on a Windows 2019/2016/2012(R2)/2008(R2)/10/8/7 operating system. This service run with Local System credentials or with Local/Domain Administrator credentials.

To change the ActiveXperts Network Monitor service credentials:

  • Open the Computer Management application that is part of the Operating System;
  • Click on the Services applet;
  • Select the ActiveXperts Network Monitor service and click on the Log On tab;
  • Choose This Account and enter the Account and Password information.

To monitor servers in a domain, enter an account that has Administration privileges on all domain members. A 'Domain Administrator' or 'Enterprise Administrator' account will suffice. You can use the UNC notation for the domain account, i.e.: DOMAIN\Account. You can also use other dotted domain notations (mysubdomain.mydomain.dom\Account) or user principle names (j.doe@mydomain.dom).

4.7. Monitoring servers in other domains

To monitor servers in another domain, ActiveXperts Network Monitor requires administrator rights on that domain. This can be established through a trust relationship between these domains. However, if there is no trust relationship, the service account credentials cannot be used.

To monitor servers in another - untrusted - domain, you need to enter alternate credentials for each Windows server in the Server Credentials table (see Options). This also applies to stand-alone servers.

If the alternate credentials fail, ActiveXperts will NOT try the ActiveXperts Network Monitor service credentials, unless you set the following registry value (you MUST restart the ActiveXperts Network Monitor service in order for changes to take effect):

HKEY_LOCAL_MACHINE\Software\ActiveXperts\Network Monitor\Server\WinLoginFallbackToService: 1

5. Built-in Checks

5.2. IP-based Checks

DHCP Server check

ActiveXperts Network Monitor can monitor DHCP servers to check IP addresses in use, IP addresses offered and IP addresses available. The DHCP server have SNMP v.1 or SNMP v.2 enabled to allow Network Monitor to retrieve the performance data.

A DHCP Server check requires the following parameters:

  • Host/IP - The IP address or hostname of the DHCP server that you want to check;
  • Maximum number of IP addresses in use - The maximum number of IP addreses in use;
  • Maximum number of IP addresses offerred - The maximum number of IP addreses offered;
  • Maximum number of IP addresses available - The maximum number of IP addreses available;
  • SNMP Community Name - The SNMP Community Name used to monitor the DHCP server. SNMP v.1 or SNMP v.2c are supported.
DNS Server check

ActiveXperts Network Monitor can resolve any DNS record and check the result against a specified value. Allowed record types include the 'A' record, 'MX' record' and 'CNAME' record'.

A DNS Server check requires the following parameters:

  • Host/IP - The IP address or hostname of the DNS server that you want to check;
  • Name - The DNS name to resolve;
  • Type - The DNS record type of the DNS record. Valid record type are: 'A Record', 'MX Record' 'CNAME Record' or 'Any Record';
  • IP address(es) - The expected IP number(s). If the query result does not include the given IP address, the check will fail. Otherwise, the check will succeed. Please note that a DNS query can return more than one IP address. In case the 'Type' was set to 'CNAME Record', the expected result is a host name, not an IP address.
FTP check

ActiveXperts Network Monitor can check the availability of an FTP site. You must pass credentials (username and password) to access the actual FTP site. If the FTP server allows anonymous access, specify 'anonymous' in the 'Account' field, and specify a valid e-mail address in the 'Password' field. With the FTP check, you can check for a file in one of the subdirectories on the FTP server, and even check for a specific pattern in the file.

An FTP check requires the following parameters:

  • Host - Hostname or IP address of the remote FTP server. If the remote FTP server is listing on a port other than 21, you can append it to the host, like this: 192.168.0.1:23
  • Passive - Specifies the way ActiveXperts Network Monitor establishes a connection with the FTP server: in Passive mode or in Active mode. Default: Passive.
  • FTP Account - Account used to access the FTP server. You cannot leave it blank. If the FTP server allows anonymous access, you must specify 'anonymous' in the 'Account field' and a valid e-mail address in the 'Password' field;
  • FTP Password - Password used to access the FTP server. If the FTP server allows anonymous access, you must specify 'anonymous' in the 'Account field' and a valid e-mail address in the 'Password' field;
  • Anonymous - If the FTP server allows anonymous access, you can click on this check box to enter credentials automatically in the 'Account' and 'Password' fields. The 'Anonymous' property is not used by the engine;
  • Check Connectivity only / Check File Existence - If you want to check availability only, you should select 'Check Connectivity' here. If you want to check for existence of a particular file, you must select 'Check File Existence';
  • Directory - If you check for file existence, you can specify a working directory where the file indicated by the 'File' field should be located. Leave it blank to use the root of the FTP site as the working directory;
  • File - The file you want to check;
  • Check file existence only / Check for a specific pattern in the file - You can check for file existence only, or for a specific pattern in the file;
  • Use binary file transfer - Indicates how the file should be transferred so it can be analyzed. Only possible if 'Check for a specific pattern in the file' is selected;
  • Pattern should (not) match - If the pattern is matched, then the result of the check can be either success or error.
HTTP/HTTPs check

ActiveXperts Network Monitor can check the availability of HTTP and HTTPs sites, on default ports (i.e.: 80 and 443) or on alternate ports. If the HTTP(s) server is not directly accessible, you can configure ActiveXperts Network Monitor to go through a Proxy server to access the particular HTTP(s) server, even passing credentials for that Proxy server (to be able to make use of the Proxy). Additionally, you can pass credentials (username and password) to access the actual HTTP(s) site if required. ActiveXperts Network Monitor supports web site content checking; contents of web sites can be searched for text patterns (including tags).

An HTTP/HTTPs check requires the following parameters:

  • URL - The location of the website in URL format (i.e. http://server[:port]/path/... format);
  • Require Server verification - A flag to indicate: HTTP or HTTPs;
  • Check for availability only / Page must contain pattern / Page must not contain pattern - In case of 'Check for Availability only', only the availability of the site is checked. In case of 'Page must (not) contain string', the content of the URL is checked for specific contents;
  • Time-out after - Time-out in seconds. If the time-out expires, the result is 'Error';

IMAP Mail Server availability check

ActiveXperts Network Monitor can check IMAP mail servers by establishing a connection on the remote IMAP port (usually port 143) and do a handshake. By handshaking, ActiveXperts Network Monitor can verify that the remote server's IMAP protocol is working well.

An IMAP Mail Server check requires the following parameters:

  • Host - Hostname or IP address of the server to be monitored;
  • Port - TCP port number of the IMAP protocol. Default: 143;
  • Send command when connected - As soon as connection is established, send a command. By default, no command string will be sent;
  • Response must include string - when connected, optionally send a command. Then wait for the response. The default response for IMAP servers includes: 'IMAP';
  • Time-out - Number of milliseconds before the check will time-out. Usually, a connection to the server will be established within 1 second. However, some slow/busy servers need more time. Recommended value is 7000 milliseconds.
LDAP check

LDAP (Lightweight Directory Access Protocol) is a protocol for querying (and modifying) directory services like Microsoft Active Directory and Novell Netware.

The LDAP check requires just one parameter:

  • LDAP Server - Hostname or IP address of the server to monitor.

The check will by default try to retrieve the full name of the queried directory service, and match the result against a pattern. One may check want to use more sophisticated queries; for this reason, the check is a VBScript check to allow customization.

NNTP News Server check

ActiveXperts Network Monitor can check NNTP news servers by establishing a connection on the remote TCP port (usually port 119) and do a handshake. By handshaking, ActiveXperts Network Monitor can verify that the remote server's NNTP protocol is working well.

  • Port - TCP port number of the NNTP protocol. Default: 119;
  • Send command when connected - As soon as connection is established, send a command. By default, no command string will be sent;
  • Response must include string - When connected, optionally send a command. Then wait for a response. The default response for NNTP servers includes: '200';
  • Time-out - Number of milliseconds before the check will time-out. Usually, a connection to the server will be established within 1 second. However, some slow/busy servers need more time. Recommended value is 7000 milliseconds.
NTP Time Server check

Commercial organizations today rely on networks of computers, all of which have clocks that are the source of time for files or operations they handle. Most of these organizations use a time server to ensure accurate time settings. The NTP protocol is the protocol used to synchronize times between workstations and servers, and external time sources. ActiveXperts Network Monitor uses the IP based NTP protocol to check availability of internal and external time sources.

An NTP check requires one parameter:

  • Time Server - Hostname or IP address of the time server.
Ping/ICMP check

Ping/ICMP checks a remote host for availability using the ICMP protocol. Local hosts should normally respond to ping requests within milliseconds. However, on a very congested network it may take up to 3 seconds or longer to receive an echo packet from the remote host. If the time-out is set too low under these conditions, it will appear that the remote host is not reachable (which is almost the truth). ActiveXperts Network Monitor checks servers for availability by sending ICMP Echo commands and wait for the responds. An ICMP time-out failure doesn't necessarily mean that the remote host is actually functioning beyond its ability to echo packets.

An Ping/ICMP check requires the following parameters:

  • Host - The host name or IP address of the computer/device you want to ping;
  • Time-out after - Maximum number of milliseconds it should take before a response is received;
  • Number of retries - The number of retries to send when a ping fails;
  • Time to Live - Maximum Time to Live (TTL) value;
  • Buffer Size (bytes) - Send buffer size.
Ping/TCP check

Ping/TCP checks a remote host to make sure it is listening to a specific TCP port. It can send multiple TCP connect requests and calculates the average connect time. You can set Connect Time limit. If exceeded, the check will fail.

An Ping/TCP check requires the following parameters:

  • Host - The DNS host name or IP address of the computer/device you want to ping;
  • TCP Port - The TCP port it should connect to;
  • Maximum average Connect Time - Maximum average connect time (msecs) allowed;
  • Number of Connect Requests - The number of times it will connect to the remote host. If one connect fails, the check will fail. The average connect time will be calculated based on the number of connects;
  • Interval (between Requests) - Number of seconds between two connect attempts.
POP3 Mail Server check

ActiveXperts Network Monitor can check POP3 mail servers by establishing a connection on the remote TCP port (usually port 110) and logon to a mailbox on that mail server.

A POP3 check requires the following parameters:

  • Host - Hostname or IP address of the server to be monitored;
  • Port - TCP port number of the POP3 protocol. Default: 110;

SNMP GET check

SNMP means: Simple Network Management Protocol. The SNMP GET message allows the Network Monitor Engine to request information about a specific variable on a remote computer or device. The agent, upon receiving a GET message, will issue a GET-RESPONSE message to the Network Monitor Engine with either the information requested or an error indication as to why the request cannot be processed.

An SNMP GET check requires the following parameters:

  • Host - Hostname or IP address of the computer/device to monitor;
  • Port - UDP port used for SNMP on the target machine/device. Default port is 161;
  • Community - The SNMP community string; Default: 'public';
  • Protocol - Indicates how the SNMP client should communicate with the remote SNMP agent. If you choose 'Automatic', the SNMP agents on both sites will negotiate and use the preferred protocol. Choose 'SNMPv1' to force the agents to use SNMP version 1; choose 'SNMP v2c' to force the agents to use SNMP version 2c;
  • OID (Numeric/Symbolic) - The Object ID; the OID is a long numeric tag or a symbolic (friendly) name, used to distinguish each variable uniquely in the MIB and in SNMP messages. If you use the numeric tag format, the OID can be prefixed by a '.'. This is optional. For example: .1.3.6.1.2.1.1.5.0 or 1.3.6.1.2.1.1.5.0. Friendly names are names like: system.sysName.0, or interfaces.ifTable.ifEntry.ifOperStatus.1.
  • Select a symbolic OID from a MIB file. - Use this button to select an alpha-numeric OID from a MIB file. You can use virtually any 3rd-party MIB file;
  • OID Data Type - The OID Data type. The following type are valid data types: Bit Stream, Counter, Integer, IP address, Object Identifier, Opaque String, String, Time Ticks and Unsigned Integer;
  • OID Data must be - Choose the condition: Equal To, Not Equal To, Less Than, Less or Equal To, Greater Than, Greater or Equal To. This condition is used to compare the actual SNMP value against the 'IOD Data Value';
  • OID Data Value - OID value that will be compared against the actual OID value, using the 'OID Data must be' operand;
  • AND / OR - To extend the condition, use AND or OR operator. On selecting AND or OR, you must specify an additional condition (Equal To, etc.) and OID Data Value.
SNMP Trap Receive check

The SNMP Trap Receive check listens for real-time network traps for processing. The SNMP Trap Receiver must be enabled at a global level. To enable the SNMP Trap Receiver:

  • On the Tools menu, choose Options;
  • Select the Advanced Tab and click on the Configure SNMP Trap Receiver button;
  • Enable the Trap Receiver by enabling the Enable SNMP Trap Receiver checkbox.

An SNMP Trap Receive check works different than other checks in Network Monitor: the SNMP Trap Receive check is event-driven. The check is not executed at timed intervals, but is triggered on a newly received trap. As a result, you cannot specify a time interval for SNMP Trap Receive checks.

An SNMP Trap Receive check requires the following parameters:

  • Receive from Host - Hostname or IP address of the computer/device to monitor. To specify any host, use '*';
  • Receive OID - The Object ID to receive. This can be a numeric OID or a symbolic OID. Type '*' to check for any OID;
  • Select a symbolic OID from a MIB file. - Use this button to select an alpha-numeric OID from a MIB file. You can use virtually any 3rd-party MIB file;
  • Receive OID Data Type - The expected OID Data type. The following type are valid data types: Bit Stream, Counter, Integer, IP address, Object Identifier, Opaque String, String, Time Ticks and Unsigned Integer;
  • Match OID Value - To check the OID data for specific value(s), enable this check box and configure the conditions in the same way as for the 'SNMP GET' check.
TCP/IP check

ActiveXperts Network Monitor can check local- or remote servers by challenging a specific port. It makes a connection to it, and performs a challenge/respond (by sending a sequence of bytes to it, wait for the respond and analyzing the received information).

A TCP/IP check requires the following parameters:

  • Host - Hostname or IP address of the server to be monitored;
  • Port - TCP port number of the protocol to be checked;
  • Send command when connected - As soon as connection is established, send a command;
  • Response must include string - When connected, optionally send a command. Then wait for a response;
  • Time-out - Number of milliseconds before the check will time-out. Usually, a connection to the server will be established within 1 second. However, some slow/busy servers need more time. Recommended value is 7000 milliseconds.
TFTP check

ActiveXperts Network Monitor can check the availability of a TFTP host by checking the existence of a file on the TFTP host. TFTP stands for 'Trivial File Transfer Protocol' and is a forerunner of the FTP protocol. It has less functionality than FTP: it is based on the (unreliable) UDP protocol, has no support for directory browsing and has not protected by a logon and password. With the TFTP check, you can check for a file in a directory on the TFTP host, and check for a specific pattern in the file.

A TFTP check requires the following parameters:

  • Host - Hostname or IP address of the remote TFTP server. If the remote TFTP server is listing on a port other than 69, you can append it to the host, like this: 192.168.0.1:8069
  • File - The file you want to check;
  • Check file existence only / Check for a specific pattern in the file - You can check for file existence only, or for a specific pattern in the file;
  • Use binary file transfer - Indicates how the file should be transferred so it can be analyzed. Only possible if 'Check for a specific pattern in the file' is selected;
  • Pattern should match / Pattern should not match - If the pattern is matched, then the result of the check can be either success or error.

  • Credentials - Select alternate Windows credentials if necessary.
Directory check

You are running Windows Server and some of your users insist on copying the contents of their notebook computer to your file server. Other users want to download everything they see on the Web. Unfortunately, you're running out of disk space. Disk space is your server's most expensive subsystem, so it's a good practice to monitor - for instance - user's Home Directories. The 'Directory check' can be of good help.

  • MB / GB / % - the upper/lower limit in Megabytes, Gigabytes or percentage;
  • Credentials - Select alternate Windows credentials if necessary.

Note: The 'Disk Space' check uses the system's administrative shares (i.e. C$, D$ etc.) to access drives on remote computers. For security reasons, these share are sometimes renamed by system administrators, for instance: MYCDRIVE$. You can type such a name in the selection box, and the Network Monitor Engine will use this administrative share name instead of the defaults administrative share name.

Event Log check

ActiveXperts Network Monitor can read Windows Event logs on local- or remote computers. It can look for specific Event Sources, Categories, Event ID's and so on. It can look for a pattern in the Description of the Event. It can do advanced filtering in Event Logs; it can look for multiple events in the Event Log, and notify the system administrator if one of the Events occurred in a specific time interval. For instance, as a network administrator, you want an alert if there's a McAfee or Norton virus message in the Application Event Log, but only if the event is posted in the last 30 minutes. ActiveXperts Network Monitor uses VBScript and WMI for this.

It enables you to fully customize Event Log filtering, speeding up performance by checking for more than one event in each cycle.

An Event Log check requires the following parameters:

  • Computer - The host name or the IP address of the computer you want to monitor;
  • Log File - The Log File to be checked. Choose the appropriate log file, for instance: 'Application', 'Security', 'System', or server-related log (like DNS, Exchange, etc.);
  • Credentials - Select alternate Windows credentials if required;
  • Information/Warning/. - Filter these event types;
  • Source - Filter events that match this Event Source;
  • Category - Filter events that match this Event Category;
  • ID - Filter events that match this Event ID;
  • User - Filter events that match this User;
  • Description matches string - Filter events that match the description string in the Event Message;
  • Only Events from the last x minutes - This options allows you to discard errors that happened in the past. For instance, if you don't want to be notified about error events that happened in the past (like a week ago), use this option;
  • This check will fail if such event is found/not found - Specify whether this check will fail or succeed when an event is found.
File check

ActiveXperts Network Monitor can monitor file existence, file size and file content. This is particularly useful in situation where log files need to be analyzed. In many organizations, batch jobs run at night and produce logging information; ActiveXperts Network Monitor can check this logging information and analyze it. It can check the existence, or search for patterns. It can also check the size of a file.

A File check requires the following parameters:

  • File (UNC Path) - The path of the file to be checked in UNC format (i.e. \\server\share\... syntax);
  • Check for: Existence only / Maximum Size / Pattern - Choose an option: just checks the existence, or check the size of a file (in KB/MB), or search for a pattern in the file
  • If condition should be True/False - If the file conditions are true, then the result of the check is: success; otherwise, the result will be: error;
  • Credentials - Select alternate Windows credentials if necessary.
Memory Usage check

ActiveXperts Network Monitor can check the memory usage of the Windows Operating System. It can monitor the total available physical memory usage, the committed memory or the pages per second.

A Memory Usage check requires the following parameters:

  • Computer - Host name or IP address of the computer to monitored;
  • Memory - select 'Minimum required Available Physical Memory' to check physical available memory; choose 'Maximum allowed Committed Memory' to check committed memory; choose 'Maximum allowed Pages Per Second' to check paging;

  • Credentials - Select alternate Windows credentials if necessary.
MS Message Queue (MSMQ) check

ActiveXperts Network Monitor monitors the status of the MS Message Queue's. It can check a queue for its length (i.e. number of jobs in the queue) or for its total size (MB).

An MSMQ check requires the following parameters:

  • Server - The host name or IP address of the server;
  • Queue Name - Name of the MSMQ queue, for instance: private$\admin_queue$;
  • Maximum Queue Length - Maximum number of jobs allowed in the queue;
  • Maximum Queue Size - Maximum amount of MB's in the queue;
  • Credentials - Select alternate Windows credentials if necessary.
MS Terminal Server check

ActiveXperts Network Monitor monitors the status of the Operating System's Terminal Server role (part of Windows 2019/2016/2012(R2)/2008(R2)/10/8/7) by checking the number of active/inactive sessions.

A Terminal Server check requires the following parameters:

  • Terminal Server Computer - The host name or IP address of the Terminal Server computer;
  • Maximum number of Active Sessions - Maximum active sessions;
  • Maximum number of Inactive Sessions - Maximum inactive sessions, i.e. disconnected and idle sessions;

Performance Counters

The Performance Counter check monitors one or more Performance counters.

One or more Performance Counters must be defined:

  • Performance Object - Type of Performance Data, e.g. Network Interface;
  • Instance - If there are multiple instance, specify which instance you want to monitor;
  • Condition - The condition that should be met, e.g. Bytes Received/sec<1000.
Printer Availability check

Even the most mechanically sound printer stops working or needs maintenance from time to time:

Printers run low on toner, run out of paper, or get jammed - unavoidable situations that prevent users from printing their documents. Unfortunately, when a printer stops working, no notice is sent to users; in addition, users can still send print jobs to the printer. If the problem is not identified and corrected, those jobs will continue to accumulate as long as the printer is unavailable. For these reasons, monitoring the printers in your organization is an important part of print management. With a well-designed monitoring strategy in place, you can receive timely notification whenever a printer stops functioning and take immediate steps to either get the printer back online or transfer print jobs to a different printer. ActiveXperts Network Monitor checks printers for availability by checking its status. Windows knows a wide range of printer status values, like: 'Running', 'In Test', 'Power Off', 'Offline', 'Power Save', and so on. If the Printer Status is not equal to Running or Power Save, then the printer is considered as malfunctioning.

A Printer Availability check requires the following parameters:

  • Print Server - The hostname or IP address of the print server;
  • Printer Name - The name of the printer, as it appears in the Windows' control panel. For instance: 'HP LaserJet 2300 Series PS';
  • Credentials - Select alternate Windows credentials if necessary.

Note: The printer availability check is based on WMI.

Process

ActiveXperts Network Monitor allows users to check processes on local- and remote computers; if a process is active, a computer is considered available. Additionally, memory usage of a process can be checked, to detect memory leaks.

A Process check requires the following parameters:

  • Computer - The host name or the IP address of the computer you want to monitor;
  • Process - The module name of the process, including the extension. For instance: alerter.exe, or explorer.exe;
  • Check memory of this process - Enable/disable memory checking of the particular process. Enter the maximum amount of memory (in MB) that a process may consume;
  • No process on this computer should consume more than - Checks for any process using more than the specified amount of memory;
  • Credentials - Select alternate Windows credentials if necessary.

Note: The process check is based on WMI; it requires WMI on both monitored and monitoring system.

Registry check

ActiveXperts Network Monitor can check a registry value on a remote Windows computer. You can compare a current registry value with a predefined pattern. You can even monitor registry changes.

A Registry check requires the following parameters:

  • Computer - The host name or the IP address of the computer you want to monitor;
  • Root Key - The registry root key, e.g. HKEY_LOCAL_MACHINE;
  • Sub Key (Path) - Registry subkey, e.g. Software\Microsoft\Windows\CurrentVersion\Setup;
  • Value - The registry value that you want to monitor;
  • Data must be - Choose the condition: Equal To, Not Equal To, Less Than, Less or Equal To, Greater Than, Greater or Equal To. This condition is used to compare the actual registry value against the predefined value;
  • AND / OR - To extend the condition, use AND or OR operator. On selecting AND or OR, you must specify an additional condition (Equal To, etc.) and OID Data Value.
Removable Drives check

Use the Removable Drive check to detect the presence of USB drives, CompactFlash, memory cards and other portable storage devices on your domain or network.

A Removable Drive check requires the following parameters:

  • Domain or List of Computers - Specify what to check: all computers in a domain, or a list of computers;
  • Exclusion List - List of pairs (computer/drive) that is excluded from the check.
Scheduled Task

With the Scheduled Task check, one can check if a scheduled task has completed successfully or not. A Scheduled Task check can only be applied to a task that should run today. I.e. you cannot check the completion of a task that ran - for instance - yesterday.

A Scheduled Task check requires the following parameters:

  • Scheduled Task Log File - the fully qualified path name to the Scheduled Task Log File (SchedLgU.txt), in UNC format; for instance: \\Server01\C$\Windows\Tasks\SchedLgU.txt
    Please note that this file is hidden in the Windows Explorer. Use a command prompt and type DIR C:\WINDOWS\TASKS to list the file;
  • Job Name - Job name, as it appears in the SchedLogU.txt file. For instance, job name should be mytask.bat according to the following log entry:
    "mytask.job" (mytask.bat)
    Finished 1/19/2006 1:43:00 PM
    Result: The task completed with an exit code of (0).
  • Completed Keyword - The keyword that determines the completion of a scheduled task. For many servers, the keyword will be Finished. However, the keyword can be different on non-English Operating Systems you are monitoring;
  • Today's Date Format - The string that determines the date format used in the Scheduled Task Log File. Note that your network servers can use different time formats. For that reason, you must specify the date format, so Network Monitor will be able to find the log entries that match the day of today. Default format: mm/dd/yyyy, i.e. month (2 digits), day (2 digits), year (4 digits), separated by a '/';
  • Match Result - The string that indicates a successful/unsuccessful completion of the task.
    A successful completion is usually determined by the following string:
    Result: The task completed with an exit code of (0);
    An unsuccessful completion is usually determined by the following string:
    Result: The task completed with an exit code of (1);
    Note that the string can be different on non-English platforms and on legacy (e.g. Windows NT 4) platforms;
    If pattern matched, result is - Indicates the result of the check if pattern is matched: Success or Error.
Service

Service monitoring involves a probe that returns the status of a service. ActiveXperts Network Monitor monitors services on local- and remote computers by checking if the status equals "Running". If so, the server is running fine, otherwise it's not.

A Service check requires the following parameters:

  • Computer - The host name or the IP address of the computer you want to monitor;
  • Service - The Windows service name. You can either the 'friendly name' (as it appears in the Control Panel) or the 'short name' (the registry key name in the HKLM\System\CurrentControlSet\Services registry hive);
  • Must run / Must not run - Determines success or error of the check. If the service should NOT be running, select 'Must not run', otherwise select 'Must run';
  • Credentials - Select alternate Windows credentials if necessary.

5.7. Database checks

Database Query (Generic)

ActiveXperts Network Monitor uses OLE DB (also known as ADO) to check availability of databases. OLE DB (sometimes written as OLEDB or OLE-DB) is an API for accessing different types of data stores in a uniform manner, including: MS SQL, MS Access, Oracle, MySQL and more.

The Database Query check requires the following parameters:

  • OLE DB (ADO) Connection String - The OLE DB connection string, for instance: DRIVER=Microsoft Access Driver(*.mdb);DBQ=\\SERVER03\Public\Northwind.mdb You can use a password in this connections string. To hide the password, you can use the <%PASSWORD%> placeholder. When using this placeholder, ActiveXperts will automatically substitute this placeholder with the 'Password' field described below;
  • Password - This is the password string (shown as asterisks) that will substitute the <%PASSWORD%> field described above;
  • Database Query - The database query. The result of the check is determined by the result of this query;
  • Match Field - The field that will be matched to determine the result of the check;
  • Value must be... - Operator and value to compare;
  • Compare as - data type.

You can use an AND/OR operator to create an advanced condition.

Note: For advanced database checks, you should use the custom VBScript database check. This check can be fully customized to meet your requirements. For instance, you can build complex queries, and analyze the query output. To create a new VBScript based database check, select Create New Check (Scripts) from the Monitor menu, choose VBScript Check..., and select 'Database.vbs'. Then, modify 'Database.vbs' to meet your requirements.

ODBC Database

ActiveXperts Network Monitor uses ODBC to check availability of a variety of databases. Most major database systems support ODBC, such as: Microsoft SQL Server, Microsoft Access, Microsoft Excel, Oracle, FoxPro, Paradox, SyBase, Informix, OpenIngres, InterBase, Progress, IBM LANDP, DB2 and AS/400. You must configure ODBC (from the Control Panel on the server where ActiveXperts Network Monitor is running on) before ActiveXperts Network Monitor can check ODBC compliant databases.

An ODBC check requires the following parameters:

  • ODBC DSN Name - the ODBC DSN (Data Source Name). This DSN entry must be configured on the server where the ActiveXperts Network Monitor service is running;
  • Username/Login - credentials required to access the database;
  • Password - credentials required to access the database.

ActiveXperts Network Monitor also provides Oracle checks based on SQLNet, like TNSPing and logon/logoff through SQLNet.

Note: The 'ADO / OLE/DB' check requires fewer configurations and is usually faster. As a result, it is the preferred way to check database, unless the database doesn't ship with an OLE DB driver.

Oracle Database

ActiveXperts Network Monitor uses SQL*Net to monitor Oracle servers for availability. The role of SQL*Net is to establish and maintain a connection between the client application and the server and exchange messages between them. SQL*Net is a software layer that is required to communicate between Oracle clients and servers. It provides both client-server and server-server communications across any network. It enables client tools to access, modify, share, and store data on Oracle servers over a Network. The communication between client applications and servers takes place across one or more networks, and is referred to as client/server communication.

ActiveXperts Network Monitor has two SQL*Net based checks for Oracle:

  • TNSPing check;
  • Logon/logoff to a database using username and password for that database.

A Database-Oracle TNSPing check requires the following parameters:

  • Server TNS name - TNS name of the Oracle database.

A Database-Oracle Logon/Logoff check requires the following parameters:

  • Server TNS name - TNS name of the Oracle database;
  • Username/Login - credentials required to access the database;
  • Password - credentials required to access the database.

5.8. Environmental checks

Devices

ActiveXperts supports a wide range of environmental devices. The vast majority of the environmental devices support the SNMP protocol. This requires a manual or a MIB browser to find the relevant OID's. Using the OID's, you can create an SNMP check" in ActiveXperts.

ActiveXperts has native suppport for the following vendors in particular: AVTech, Kentix and Sensatronics. ActiveXperts offers demo environmental devices in the ActiveXperts extranet, to let trial users actually use the devices using the ActiveXperts software. These devices can be purchased directly from ActiveXperts, either with or withour a software license.

5.9. Miscellaneous checks

Serial Device check

ActiveXperts Network Monitor allows you to query a serial device (e.g. a modem, a weight indicator, etc.) and analyze the response. The device must have a serial port interface, for instance an RS-232 interface. USB devices are also supported, but only if the device ships with a driver to emulate a serial port.

A Serial Device check requires the following parameters:

  • Device - Device driver to use. You can either use a Windows telephony device (recommended) or a physical COM port (directly);
  • Flow Control - Select the type of flow control to use. The following values are valid: Default, None, Hardware, Hardware+Software. You can only select 'Flow Control' if 'Device' is set to a direct port (i.e. not a TAPI device);
  • Baudrate - Select the baudrate (port speed). You can only select 'Baudrate' if 'Device' is set to a direct port (i.e. not a TAPI device);
  • Send command when connected - As soon as connection is established, send a command;
  • Response must include string - Expected response;
  • Time-out - Number of milliseconds before the check stop reading information from the device.
Users & Groups

ActiveXperts Network Monitor monitors groups and group membership. In case of unexpected members in certain groups (for instance: unexpected Domain Admins members), it'll notify the network administrators.

ActiveXperts Network Monitor checks different kinds of Directory Services, for instance: Active Directory, or Novell NDS. You can configure ActiveXperts Network Monitor to check user accounts (locked out, disabled, etc.), groups, group membership, organizational units, and so on.

The User/Group Membership check requires the following parameters:

  • Domain - The Active Directory domain. In case you want to monitor a stand-alone server (i.e. a server not member of a domain), you can enter the computer name;
  • Group - The group name to the Active Directory group you want to check, like: Domain Admins;
  • Users - Specify the names of the users that are allowed in the specified group. If the groups appears to have members who are not entered in this 'Users' field, the check will fail.

6. Scripted Checks

6.1. PowerShell (Windows)

Introduction

PowerShell is a command-line shell with associated scripting language from Microsoft. It was released in 2006, and is part of Windows Operating Systems currently support by Microsoft.

Enabling PowerShell scripts

Out of the box, the Operating System does not allow you (or ActiveXperts Network Monitor) to run PowerShell scripts. You must enable PowerShell scripting first from the command line.

To allow execution of Powershell scripts in ActiveXperts Network Monitor, please do the following:

  • Open a new command prompt (for instance by typing CMD.EXE" in the Windows Start-Run line)
  • Type PowerShell.exe and press <Enter>>
  • Type Set-ExecutionPolicy Unrestricted and press <Enter>
Using PowerShell scripts in ActiveXperts Network Monitor
In order to use PowerShell with Network Monitor, PowerShell needs to be installated on the monitoring server. It is not required to have PowerShell installed on the monitored server!

ActiveXperts Network Monitor ships with a set of PowerShell that run out of the box. These can be used to check servers and can be modified in order to meet your requirements. ActiveXperts Network Monitor requires the output (i.e. StdOut) of the PowerShell script to be formatted according to the following syntax:

      [ SUCCESS | ERROR | UNCERTAIN]: { <explanation> } { DATA:<value>}

The <explanation> will be shown in the 'Last Response' column in the Manager application. The <value> field will be shown in the 'Data' column in the Manager application. For example:

      ERROR: Free disk space is less than 40 GB DATA:34

or

      SUCCESS: Free disk space is more than 40 GB DATA:102

6.2. VBScript (Windows)

ActiveXperts Network Monitor contains a comprehensive set of built-in monitoring checks. The product is designed to let operators write their own monitoring checks and use them in the product. ActiveXperts uses VBScript because it is the most popular scripting language in Windows environments.

ActiveXperts ships with a collection of cooked VBScript files and routines. These scripts are located in the folder '\Scripts\Monitor (vbs)' folder, and can be used out of the box. Feel free to modify these scripts.

VBScript check routines should return one of the following values:

  • -1 (True); Return -1 in case the check is successful. For instance, if your function checks the existence of a certain directory, and it does exist, then return -1;
  • 0 (False); Return 0 in case the check is not successful. For instance, if your function checks the existence of a certain directory, and it does not exist, then return 0;
  • 1 (Unknown); Return 1 in case the check cannot determine True or False. For instance, if your function checks the existence of a certain directory on a server, but it cannot find the server at all (for instance because the computer is down), return 1;

Keep the following in mind when writing a new VBScript function:

  • The routine must be a Function, not a Sub;
  • The Function must return True (-1), False (0) or Unknown (1);
  • The SYSEXPLANATION and SYSDATA variables must be declared (e.g. 'Dimmed') because they are used internally by ActiveXperts Network Monitor;
  • Use the SYSEXPLANATION system variable to add your own explanation to the result of the function; this SYSEXPLANATION is shown in the client program each time the check is made;
  • Use the SYSDATA system variable to store any relevant data, if any. This data field is also shown in the Manager ('Data' column) and is also written to the log files;

Function template:

Const retvalUnknown = 1
Dim SYSDATA, SYSEXPLANATION

Function Foo( var1, var2, ..., varn )
   If( Not Pre-condition ) Then
      SYSEXPLANANTION = "Unable to determine..."
      Foo = retvalUnknown
   Else
      If( condition ) Then
         SYSEXPLANANTION = "Yes it is true because ..."
         SYSDATA = 5
         Foo = True
      Else
         SYSEXPLANANTION = "No it's not true because ..."
         SYSDATA = 6
         Foo = False
      End If
   End If
End Function  

To add a VBScript check:

  • From the Monitor menu, choose Create New Check (Scripts) and choose VBScript Check...;
  • Select a VBScript File and a VBScript function;
  • Enter the required parameters and press OK.

To create a new VBScript file, choose Create New File from the File selection box and a new file will be created. To create a new function in a VBScript file, choose Add New Function from the Function selection box and a new function will be written.

WMI (Windows Management Instrumentation)

If you plan to write check routines based on WMI (Windows Management Instrumentation), be sure you have WMI installed on the ActiveXperts Network Monitor server and on the server that you want to monitor.

WMI is part of the Windows 2019/2016/2012(R2)/2008(R2)/Vista/10/8/7 operating system by default.

ActiveXperts has a collection of hundreds of WMI samples. You can use these samples as a base for your new check routines. You can find these samples at www.activexperts.com/admin/scripts/wmi/.

ADSI (Active Directory Service Interfaces)

If you plan to write check routines based on ADSI (Active Directory Service Interfaces), be sure you have ADSI installed on the ActiveXperts Network Monitor server and on the server that you want to monitor. ADSI allow you to access not only Windows Active Directory, but also Windows Local User information from the SAM database, and other User Databases like Novell Bindery and so on.

ActiveXperts provides some useful ADSI scripts on its website, at www.activexperts.com/admin/scripts/adsi/. You can use these samples as a base for check routines that you write yourself.

VBScript troubleshooting

It's recommended to write and test a custom script as a batch job first, before integrating the script in the Network Monitor software. It is important to write bug-free scripts; a script that is poorly written may block all VBScript based checks at the end. ActiveXperts Network Monitor has a multi-threaded engine, and is capable of processing eight VBScript checks simultaneously. However, when all VBScript threads are blocked, there's no way the Network Monitor can check other VBScript based checks.

General VBScript Guidelines:

1. Location of the script

The batch script must be located in the ActiveXperts Network Monitor installation directory or one of its sub-directories;

2. Use a batch script to test the script

Before integrating the script in the Network Monitor software, test it as a batch job first.

Example:

Option Explicit
Const retvalUnknown = 1
Dim SYSDATA, SYSEXPLANATION

Function IsWeekend()
    If WeekDay( Date() ) = VBSaturday or WeekDay( Date() ) = VBSunday Then
        SYSEXPLANATION = "Yes, weekend"
        IsWeekend = True
    Else
        SYSEXPLANATION = "No, no weekend"
    IsWeekend = False
    End If
End Function

Wscript.Echo "IsWeekend: " & IsWeekend()  ' Use Wscript ONLY for testing

(NOTE: the piece of code in green is the code that will be copied to the Network Monitor script when tested well)

Save this file as a .vbs file, for instance: test.vbs. Then, run it from the command-line like this: CSCRIPT TEST.VBS

3. Don't use WScript objects in your scripts

Any commands and functions related to a console or User Interface should be avoided. Keep in mind that the Network Monitor Engine runs as a service, and has no user interface. Message boxes and console output statements may lead to undesirable results. Some objects will not work in Network Monitor:

  • Wscript object;
  • WshArguments object;
  • WshEnvironment;
  • WshNamed;
  • WshNetwork;
  • WshRemote and WshRemoteError;
  • WshScriptExec
  • WshShell
  • WshSpecialFolders;
  • WshUnnamed;
  • WshUrlShortcut.

Also, avoid functions that display a dialog box, like InputBox.

4. Using the ActiveXperts VBScript debugger object

ActiveXperts Network Monitor includes a debug control to print debug information to a log file while the Network Monitor Engine interpreter runs the script. The debug control is called ActiveXperts.VbDebugger.

ActiveXperts.VbDebugger has the following properties:

  • DebugFile - the name of the debug output file. The path of the file must be a valid path. If the file does not exists, the file will be created.

ActiveXperts.VbDebugger has the following functions:

  • ClearDebugFile - this function creates a new, empty debug file. Use it to clear debug output from a previous debug session; The function has no parameters;
  • Write - this function writes a piece of text to the debug file. The functions requires one parameter: the string to write to the file. If you want a newline at the end, you must pass it manually yourself as part of the parameter, or use the WriteLine function;
  • WriteLine - this function writes a piece of text to the debug file, including a newline at the end. The functions requires one parameter: the string to write to the file;
  • Sleep - this function will hold the script for some milliseconds. The function requires one parameter: the number of milliseconds.

The following sample shows how to use the debug control:

Function IsWeekend()
    Set objDebugger = CreateObject( "ActiveXperts.VbDebugger" )
    objDebugger.DebugFile = "c:\temp\debug.txt"
    objDebugger.ClearDebugFile  ' Clear the file is desired
    objDebugger.Write "Function WeekDay will be called now... " & vbCrLf
    If WeekDay( Date() ) = VBSaturday or WeekDay( Date() ) = VBSunday Then
        SYSEXPLANATION = "Yes, weekend"
        IsWeekend = True
    Else
      SYSEXPLANATION = "No, no weekend"
        IsWeekend = False
    End If
    objDebugger.Sleep 3000 ' Hold the script for three seconds
    objDebugger.Write "Exit IsWeekend" & vbCrLf
End Function

Visit www.activexperts.com/support/network-monitor/online/vbscript/ for detailed information on writing custom VBScript checks. It contains detailed information about writing custom scripts, describes the debugger and contains various samples.

6.3. Remote Command (Windows)

ActiveXperts Network Monitor supports the execution of a command on a remote server, and base the result on the outcome of standard output.

The check is executed by installing a service on the remote monitored server. This service is called 'ActiveXperts Remote Command Service' (AxRemCmd). After installation, the service is started and is ready for a request from the Network Monitor service. After the command has been executed, the service is uninstalled by the Network Monitor service.

ActiveXperts Network Monitor requires the output (i.e. StdOut) to be formatted according to the following syntax:

[ SUCCESS | ERROR | UNCERTAIN]: { <explanation> } { DATA:<value>}

The <explanation> will be shown in the 'Last Response' column in the Manager application. The <value> field will be shown in the 'Data' column in the Manager application. Samples:

ERROR: Free Disk space is less than 40 GB DATA:34
SUCCESS: Daemon 'LPD' is running

6.4. SSH (Linux,Unix)

The Secure Shell Script (SSH) check allows you to login to a Linux/Unix host and run a shell script in a secure way. There are two ways to login: using an account and a password, or using an account and a private key file.

ActiveXperts Network Monitor requires the output (i.e. StdOut) to be formatted according to the following syntax:

[SUCCESS | ERROR | UNCERTAIN]: { <explanation> } { DATA:<value>}

The <explanation> field is displayed in the 'Last Response' column in the Manager application. The <value> field is displayed in the 'Data' column in the Manager application.

Samples:

ERROR: Free Disk space is less than 40 GB DATA:34
SUCCESS: Daemon 'LPD' is running

Sample Shell Script to check directory existence:

#!/bin/sh

# Macro definitiions
FREE=`free -m | awk '/^Mem:/  { printf( "%s\n", $4 ); }'`
USED=`free -m | awk '/^Mem:/  { printf( "%s\n", $3 ); }'`

# Validate number of arguments
if [ $# -ne 2 ] ; then
    echo "UNCERTAIN: Too few arguments Usage: memory <free>|<usage> <size>";
    exit 1;
fi

# Validate arguments
if [ $1 != "free" ] && [ $1 != "used" ]; then
   echo "ERROR: Wrong parameters entered  DATA:0";
fi

# Check free memory
if [ $1 == "free" ] ; then
   if [ $FREE -gt $2 ]||[ $FREE == $2 ] ; then
      echo "SUCCESS: Free memory is [$FREE MB], minimum required=[$2 MB] DATA:$FREE";
   else
      echo "ERROR: Free memory is [$FREE MB], minimum required=[$2 MB] DATA:$FREE";
   fi  
fi  

# Check used memory
if [ $1 == "used" ] ; then
   if [ $USED -lt $2 ]||[ $USED == $2 ] ; then
      echo "SUCCESS: Used memory is [$FREE MB], maximum allowed=[$2 MB] DATA:$FREE";
   else
      echo "ERROR: Used memory is [$FREE MB], maximum allowed=[$2 MB] DATA:$FREE";
   fi  
fi

ActiveXperts Network Monitor installs a collection of SSH monitoring checks. In a default installation, it is located in folder:
C:\ProgramData\ActiveXperts\Network Monitor\Scripts\Monitor (ssh)

7. Alert Notifications

7.1. Introduction

Alert Notifications are sent:

  • When a Check fails - After a configurable number of errors (error threshold), the check is set to Failed. Probably you want to send notifications to the system operator via the SMS or e-mail to notify him that the server/device is down; By default, only one notification is sent after a failure; if you want to be notified regularly after a failure, it can be configured by pressing the Advanced button in the Monitoring Check Properties tab;
  • When a Check recoveres from the 'Failed' status - ActiveXperts Network Monitor has the ability to repair a computer/device. It can be useful to send an alert to the operator to tell him that the previous error is no longer there.

Notification Settings are software settings that are global for all monitoring checks. You can configure these from the Tools menu, by selecting the Notification Settings item.

For all notification types - except pager notifications and SNMP traps - you can use an Address Book. In the Address Book, you can organize notification recipients in groups. Groups can be used in any check. But you can still define a custom list of recipients for individual checks.

The following alert notification types are supported by ActiveXperts Network Monitor:

  • E-mail notifications;
  • SMS Text notifications;
  • Numeric Pager notifications;
  • Alpha-numeric Pager notifications;
  • SNMP Trap notifications;
  • Network notifications.
Default Alert Notification settings for new Monitoring Checks

Default Alert Notification settings apply to new Monitoring Checks. These values can be defined in the Notifications Settings dialog:

  • On the Tools menu, click Notification Settings;
  • Select the Default Alerts tab.

The following Alert Nootification defaults can be configured:

  • E-mail notification when check fails - this value indicates whether an e-mail notification should be sent when a check fails;
  • Email notification when check recovers from failure - this value indicates whether an e-mail notification should be sent when a check is successful after a failure;
  • SMS notification when check fails - this value indicates whether an SMS notification should be sent when a check fails;
  • SMS notification when check recovers from failure - this value indicates whether an SMS notification should be sent when a check is successful after a failure;
  • Pager notification when check fails - this value indicates whether a Pager notification should be sent when a check fails;
  • Pager notification when check recovers from failure - this value indicates whether a Pager notification should be sent when a check is successful after a failure;
  • SNMP Trap notification when check fails - this value indicates whether an SNMP Trap notification should be sent when a check fails;
  • SNMP Trap notification when check recovers from failure - this value indicates whether an SNMP Trap notification should be sent when a check is successful after a failure;
  • Network notification when check fails - this value indicates whether a network notification should be sent when a check fails;
  • Network notification when check recovers from failure - this value indicates whether a network notification should be sent when a check is successful after a failure;
  • Notification Frequency Defaults - specifies how often a notification (e-mail, SMS and so on) should be sent after a failure. By default, a notification is sent only once after failure; however, you can configure to notify every x minutes after failure;

7.2. Address Book

The Address Book contains all Contacts and Contact Groups used to send out Alert Notifications when there's an incident.

A Contact has properties like 'First Name', 'Last Name', 'E-mail Address' and 'SMS Mobile Number'.
You can group one or more Contacts in one or more Contact Groups.

At a Check level, you can assign Contact Groups and/or Contacts to the Alert Notification properties of the Check. The Contact Adresses will be used to send out the Notifications.

The Address Book is also used with Reports, where Reports are scheduled and sent as e-mail attachments to those who want to receive the Reports.

NOTE: It is recommended to assign Contact Groups rather than individual Contacts to the Check's Alert Notification properties. With a Contact Groups, you don't need to change the Check's properties when there's a new User.. You just need to modify the Contact Group membership list one time.

7.3. E-mail Alert Notifications

To use SMTP e-mail notifications, the ActiveXperts Network Monitor service must have access to a (secure) SMTP server to send out e-mails. It can be any SMTP (secure) compliant mail server.

ActiveXperts Network Monitor supports the SSL/TLS secure protocol, as well as STARTTLS, is compliant with SMTP servers that require SMTP authentication, like Microsoft Exchange. SMTP AUTH is the protocol that is used to verify that you are one of the users of the SMTP server. ActiveXperts Network Monitor is RFC 821 and RFC 822 SMTP AUTH compliant. It also supports multiple character sets, including English (ISO-8859-1), Chinese (big5) and Japanese (ISO-2202-JP).

E-mail Notification Global Settings

To configure global e-mail Alert Notification Settings use the 'ActiveXperts Network Monitor Manager':

  • On the Tools menu, click Notification Setup and select the E-mail tab;
  • Enable the Enable E-mail Alert Notifications checkbox to enable e-mail notifications;
  • The SMTP Server can be an IP address (like 10.0.0.1), a host name (like mail.mydomain.com) or a NetBIOS name (like EXCHANGE01); this is the server that will send out the actual notification messages to the recipients;
  • If your SMTP server is a secure server, select the Security Protocol;
  • If your SMTP server requires authentication, click the Authentication checkbox and provide a logon and password;
  • Provide Sender E-mail Address (required) and Sender's Display Name (optional). The recipient will see this name/address as the sender, and all replies will be delivered to this mail account;
  • Use the E-mail Address Book to organize e-mail recipients in groups. The Address Book can be used for all checks. The E-mail Address Book makes configuration easier, because you don't have to configure a separate list of recipients for each monitoring check; however, it is still possible to configure a separate list of recipient for any check;
  • Click on Format Message to edit the e-mail template and to enable/disable RTF (HTML) formatting. In this dialog, you can also set the preferred character set: English (ISO-8859-1), Chinese (big5) or Japanese (ISO-2202-JP). Enable RTF (HTML) formatting to support HTML tags. If you switch on RTF formatting, you must use the <br> tag (or an alternative tag) to insert new lines.
  • Click on Secondary Server to specify a fallback server. The secondary server is only used if the primary SMTP mail server is down while attempting to send out an SMTP notification.

To test the E-mail Notification Settings, use the Test SMTP Server button. It will send a request the Network Monitor Engine to send an E-mail message using the given settings.

Message Templates are discussed in topic Message Templates.

Note: Be aware of e-mail clients that do not have Rich Text enabled for security reasons.

E-mail Notification Check Settings

For each check, you can make the following configuration settings:

  • Notify when check fails - when the check is set to 'Failure', a message is being sent. Default: On;
  • Notify when a check recovers from a failed status - when the check turns from 'Failure' to 'Success', a message is being sent. Default: Off;
  • For both 'Success' and 'Failure' status changes, you use the Address Book recipient groups, or use a custom recipient list.
  • For both 'Success' and 'Failure' status changes, you use the Address Book recipient groups, or use a custom recipient list.

7.4. SMS Alert Notifications

ActiveXperts Network Monitor supports alpha-numeric SMS messaging in three ways:

  • Using GSM Modem (or GSM phone), connected to the Network Monitor server by serial cable or IP connection;
  • Using SMSC HTTP protocol. Requires a subscription with an SMSC provider providing the HTTP(s) protocol for sending;
  • Using SMSC SMPP service provider. This requires Auron SMS Server on one of your network computers (or on the same machine as ActiveXperts Network Monitor).
SMS Notification Settings Global Settings

To configure global SMS Alert Notification settings:

  • On the Tools menu, click Notification Setup and select the SMS tab;
  • Enable the Enable SMS Alert Notifications checkbox to enable SMS notifications;
  • Choose Use GSM Modem. to send SMS notifications via a GSM modem, or choose Use ActiveXperts SMS Messaging Server to forward SMS notification requests to Auron SMS Server;
  • Click on the Format Message button to edit the SMS template. Message Templates are discussed in Chapter 3.15: "Message Templates".
SMS Notification Global GSM Modem Settings

In the GSM Modem setup dialog, you must select the Windows telephony device (recommended) or a physical COM port (directly) that is used to connect to the physical GSM modem. As soon as you select the device from the list, the Network Monitor Manager tries to detect the device connected to the Network Monitor server. If a GSM modem cannot be detected, a log file is provided for troubleshooting purposes.

Use the Advanced Settings button to configure advanced communication settings.

SMS Notification Global SMS Messaging Server Settings

ActiveXperts SMS Messaging Server is an SMS messaging framework to enable sending, receiving and processing of SMS messages. You can relay SMS notifications from any application (including Network Monitor) to the SMS Messaging Server.

With ActiveXperts SMS Messaging Server, you can benefit from the product's SMPP support. SMPP is the fastest and most reliable way of sending bulk SMS messages.

To relay Network Monitor SMS notifications to ActiveXperts SMS Messaging Server, you must install the ActiveXperts SMS Messaging Server Client Tools on the server that has the Network Monitor service running. Once installed, you can select an SMPP channel.

SMS Recipient Number

The SMS recipient number must be in International Number Format: the SMS number, prefixed by the international dialing number and the '+' character. The use of the '+' character is required. For example: +4412345678

SMS Notifications Check Settings

For each check, you can make the following configuration settings:

  • Notify when check fails - when the check is set to 'Failure', a message is being sent. Default: On;
  • Notify when a check recovers from a failed status - when the check turns from 'Failure' to 'Success', a message is being sent. Default: Off;
  • For both 'Success' and 'Failure' status changes, you use the Address Book recipient groups, or use a custom recipient list.

Note: To log all modem operations, you must enter a valid file name in the following registry entry:
HKLM\Software\ActiveXperts\Network Monitor\Server\Trace\NotifySms

7.5. Pager Alert Notifications

ActiveXperts Network Monitor supports numeric DTMF Paging (using a Hayes compatible modem) and alpha-numeric paging (using an SNPP provider).

The modem must be connected to the server where the 'ActiveXperts Network Monitor Service' (Engine) is running. When there's a failure, ActiveXperts Network Monitor will use the modem to dial-out to the Pager recipients.

Pager Notification Global Settings

To configure global Pager Alert Notification settings:

  • On the Tools menu, click Notification Setup and select the Pager tab;
  • Enable the Enable Pager Alert Notifications checkbox to enable pager notifications;
  • Choose Use alpha-numeric paging to send alpha-numeric pager messages using an SNPP provider, or choose Use numeric DTMF paging to send numeric DTMF pager messages using a standard Hayes compatible modem.
Pager Notification Global Settings - alpha-numeric SNPP paging

In the Pager/SNPP setting dialog:

  • Enter the Host (host name or IP address) of your SNPP paging provider. Enter the IP port used to connect to your SNPP provider (default: 444);
  • If your SNPP provider requires a password, enable the Password required option and provide a valid password.
  • In the Time-out field, enter the time-out (in millisecond) used to connect to the SNPP provider.
Pager Notification Global Settings - numeric DTMF paging

In the Pager/DTMF setting dialog:

  • Select a Modem from the list. The list is inherited from the list of Telephone Devices of the operating system (configured in the Control Panel on the system where the Network Monitor Engine is installed). If there is no modem driver installed for your device, you can also select a direct com port. Use the Test Pager Settings button to test the configuration;

Note: A Pager recipient can only consist of the following characters:
T0,1,2,3,4,5,6,7,8,9,+,-,*,#@,a,b,c,d,A,B,C,D,w,WT

Pager Notification Check Settings

For each check, you can make the following configuration settings:

  • Notify when check fails - when the check is set to Failure, a message is being sent. Default: On;
  • Notify when a check recovers from a failed status - when the check turns from 'Failure' to 'Success', a message is being sent. Default: Off;
  • For both Success and Failure status changes, you use the Address Book recipient groups, or use a custom recipient list.

Note: To log all Pager operations, you can enter a valid file name in the following registry entry:
HKLM\Software\ActiveXperts\Network Monitor\NotifyPager

7.6. SNMP Trap Alert Notifications

ActiveXperts Network Monitor supports SNMPv1, SNMPv2c and SNMPv3 Trap notifications.

SNMP Trap Notification Global Settings

To configure global SNMP Trap notification settings:

  • On the Tools menu, click Notification Setup and select the SNMP Traps tab;
  • You can now configure a list of SNMP Traps. Usually, you will need just one trap to send out to a network management station, but you can define multiple traps. Press the Add Trap button to add a trap to the list; press the Edit Trap button to edit the parameters of a specific trap, and press the Remove Trap button to remove a trap from the list.
  • When you use the Add Trap button or the Edit Trap button, you can configure the parameters of a single trap. These parameters are described below.
SNMP Trap Parameters

A trap consists of the following parameters:

  • Agent - the host name or IP address of the (remote) SNMP network management station;
  • Port - the port used for sending SNMP traps; default: 162;
  • Community - the community of SNMP devices. Default: public;
  • Protocol Version - Select either SNMPv1, SNMPv2c or SNMPv3. Default: SNMP v2c;
  • SNMPv3 authentication - enter SNMPv3 login parameters to be used with SNMPv3 traps;
  • OID - the Object Identifier; Network Monitor accepts numeric and alpha-numeric OID's, for instance: system.sysName.0, or 1.3.6.1.2.1.1.5.0;
  • OID Data Type - this field indicates the type of data that is sent to the (remote) network management station. Network Monitor supports the following data types: strings, integers, IP addresses, time ticks, counter types, OID's and some other, less frequently used types;
  • OID Value - the actual value that is sent over the network. You can include notification variables, like <%DISPLAYNAME%> , <%TIME%>, or <%HOST%>. For a complete list of notification variables, see also Appx E. Notification Variables;
  • Generic Trap - this optional field is only used with SNMP v1.
SNMP Trap Notifications Check Settings

For each monitoring check, you can configure the following settings:

  • Notify when check fails - when the check fails, a message is being sent. Default: On;
  • Notify when check recovers from a failed status - when the check reverts to 'success', a message is being sent. Default: Off;
  • For both Online and Offline status changes, you can choose to use Global SNMP Trap List as defined in the Global SNMP Trap Notification Settings, or use a Custom SNMP Trap List.

7.7. Network Alert Notifications

Network Notifications are the well-known 'Net Send' (or 'NetPopup') messages over the network. Only machines that support NetBIOS can send/receive these messages. NetBIOS messages can be sent to users and/or computers.

Network Notification Global Settings

To configure global Network Alert Notification settings:

  • On the Tools menu, click Notification Setup and select the Network Popup tab;
  • Enable the Enable Network Popup Notifications checkbox to enable network notifications;
  • Use the Network Popup Address Book to organize NETBIOS recipients in groups. The Address Book can be used for all checks. The Address Book makes configuration easier, because you don't have to configure a separate list of recipients for each monitoring check; however, it is still possible to configure a separate list of recipient for any check;
  • Click on Format Message to edit the network message template. Message Templates are discussed in Chapter 3.15: "Message Templates".

To test the Network Notification Settings, use the Send Test Message button. It will send a request the Network Monitor Engine to send an network popup message using the given settings.

Network Notifications Check Settings

For each check, you can make the following configuration settings:

  • Notify when check fails - when the check is set to Failure, a message is being sent. Default: On;
  • Notify when a check recovers from a failed status - when the check turns from 'Failure' to 'Success', a message is being sent. Default: Off;

7.8. Message Templates

A notification message can be customized. Use the Format Message button in the appropriate global notification tab of the Notification Setup dialog from the Tools menu. Each notification type has its own message template.

Inside a message template, you can use system variables. These variables are substituted each time the message is sent out. System variables must be enclosed between <% and %> strings, for example: <% DATE %>. See also Appx E. Notification Variables for a complete list of Notification Variables.

Message Template Example

Example of a message template:

Message from ActiveXperts Network Monitor, <% DATE %> <%TIME %>:
Item:    <% DISPLAYNAME %>
Result:  <% RESULT %>
Explanation:<% EXPLANATION %> 

Note: Using newlines in SMS Message Templates is NOT recommended. Many GSM phones don't know how to handle newlines and will display bad characters.

7.9. Dependencies

Dependencies allow you to create a hierarchy of checks that depend on each other. This hierarchy is not related to the Folder structure of your Network Monitor configuration. Dependencies prevent you and your network administrators from being overwhelmed with notifications when a central router or server goes down. Without a dependency configuration, the failure of a central server or device would cause a failure of other servers, and as a result many notifications would be sent out. There are at least two items involved when configuring dependencies:

  • Dependee - the computer/device that plays a central role. A failure of this 'Dependee' device or server would cause failures of other servers and devices (so called 'Dependers');
  • Depender(s) - servers, devices or folders that depend on the 'Dependee'.

A dependee cannot be a folder, only a check. You can make other checks and/or folders dependent on the Dependee. It is recommended to use Folders rather than Checks as a Depender, because it is dynamic.

For more information about Dependencies, visit the Online Dependency Guidelines on the ActiveXperts web site. It contains a good sample and some best practice hints.

8. Web Access

8.1. Introduction

ActiveXperts Web Access is a comprehensive web interface, designed for mobile devices, tablets and PC's. It allows users you to see those parts of the Network Monitor configuration that they have access to.

ActiveXperts Web Access has a mobile first, reponsive design and can be viewed by any browser, on any (touchscreen) mobile device, tablet or PC, running iOS, Anndroid or Windows.

ActiveXperts Web Access focusses on Network Monitors on Folders. Each Folder in the Network Monitor configuration can be published, each one having its own credentials. Each Folder can have one or more so called 'Filters', so users can filter on different aspects, for instance displaying only Failure results, or displaying only VMware and Citrix checks, or combined.

8.2. Web Access Sample

The following sample shows the basics of ActiveXperts Web Access:

ActiveXperts Network Monitor is used by company Northwind Traders Ltd. to monitor all internal servers and devices. The domain is named 'northwind.intra' and is divided into two sub-domains:
- Domain: 'usa.northwindtraders.intra'
- Domain: 'emea.northwindtraders.intra'

There's the following Folder structure configured in Network Monitor:

Entire Network
  |-- usa.northwindtraders.intra (folder-id #1)
        |-- system administration (folder-id #1000)
        |-- production (folder-id #1001)
        |-- webservers (folder-id #1002)
        |-- vmware (folder-id #1003)
  |-- emea.northwindtraders.intra
        |-- sales (folder-id #2001))
        |-- support (folder-id #2002))

The first step is, to publish ActiveXperts Web Access through Microsoft Information Services (IIS).
The root of the Folder to be published is C:\ProgramData\ActiveXperts\Network Monitor\WebRoot\ (default).

Use the ActiveXperts Web Access Configuration program to publish the above. In this sample, it is published as:
https://webaccess.northwindtraders.intra:8080

A port is opened on the firewall with NAT translation, to make Web Access available from the ublic internet through the following URL:
https://webaccess.northwindtraders.com

In this configuration, we define the following Views:

View: ALL

  • Displays: all servers of northwindtraders.intra (so both 'usa' and 'emea')
  • Accessible through: https://webaccess.northwindtraders.com/1/
  • Selectable Filters: All Results - Failed Only - ICMP Only

View: System Administration

  • Displays: all servers in folder 'system administration'
  • Accessible through: https://webaccess.northwindtraders.com/1000/
  • Selectable Filters: All Results - Failed Only - Active Directory, DNS, DHCP only - Disk Space only
  • View: Production

  • Displays: all servers in folder 'production'
  • Accessible through: https://webaccess.northwindtraders.com/1001/
  • Selectable Filters: All Results - Failed Only - MS SharePoint and MS Dynamics Only
  • View: Support

  • Displays: all servers in folder 'support'
  • Accessible through: https://webaccess.northwindtraders.com/1002/
  • Selectable Filters: All Results - Failed Only - Helpdesk system only
  • Index page

  • Displays: an index of all of the above views
  • Accessible through: https://webaccess.northwindtraders.com/
  • Permissions

    In this samples, there are the following Active Directory groups:

    • northwindtraders.intra\Administrators
    • northwindtraders.intra\Production
    • northwindtraders.intra\Support

    Members from the 'Production' should not have access to monitoring results other than https://webaccess.northwindtraders.com/1001/. To achieve this, the following permssions are defined for C:\ProgramData\ActiveXperts\Network Monitor\WebRoot\1001\:

    • northwindtraders.intra\Administrators: Full Control
    • northwindtraders.intra\Production: Read+Execute

    Members from the 'Support' should not have access to monitoring results other than https://webaccess.northwindtraders.com/1002/. To achieve this, the following permssions are defined for C:\ProgramData\ActiveXperts\Network Monitor\WebRoot\1002\:

    • northwindtraders.intra\Administrators: Full Control
    • northwindtraders.intra\Support: Read+Execute

    8.3. Host Web Access on IIS

    To make ActiveXperts Web Access available to mobile devices, tablets and PC's, you neecd to host it first on Microsoft Internet Information Services (IIS). It is required that the 'Web Server' role is installed on your server. The 'Web Server' role can be installed using Windows' Server Manager Tool

    After the 'Web Server' role has been installed and runnin therer are two ways to host ActiveXperts Web Access on IIS:

    1. Automatically, using the ActiveXperts Web Access Configuration tool
    2. Manually, using Windows' Internet Information Services (IIS) Manager
    Configure Web Access Hosting using ActiveXperts Web Access Configuration Tool

    You can setup hosting Web Access on IIS using ActiveXperts Web Access Configuration Tool:

    • Start the ActiveXperts Web Access Configuration Tool from the Manager.
      To do so, Open Web Access from the Tools menu and select Web Access Configuration....
    • Press the Host on IIS button;
    • Press the Connect button. All web sites on the selected IIS server will be listed;
    • Choose a Site Name (default: ActiveXperts Web Access);
    • Select HTTPs or HTTP and make sure you enter a unique Port Number;
    • Press the Add New Site button.
    Configure Web Access Hosting using IIS Manager

    To setup hosting Web Access manually in IIS, use the Internet Information Services (IIS) Manager and perform following steps:

    1. Click Start, Administrative Tools, Internet Information Services (IIS) Manager. This will open the IIS manager.
    2. In the left column you will see the machine name, expand local machine and right click on Sites then open Add new Web Sites;
    3. Fill all the necessory details which is as below:
      - Site Name; Name of Site, e.g. ActiveXperts Web Access
      - Physical path; Default: C:\ProgramData\ActiveXperts\Network Monitor\WebRoot\
      - Type; Type of Web site. Default: https
      - IP Address; IP Address of the site.
      - Port; Port number on which site will run.
      - Host name; Domain name of site.

    8.4. Web Views

    A Web View is an ActiveXperts Web Access Page with the following properties:

    • It represents one Folder in the Network Monitor configuration;
    • It is accessible through the following URL: http://web-access-root/folder-id/, for instance: http://axnetworkmonitor/1/;
    • It has one or more so called Filters. By default, filters All Results and Failed Results are defined, but you can have many Filters, to filter Results and/or Check Types;
    • A Web View has permission properties, defined by the NTFS Folder permissions;
    • A Web View is optionally listed in the root: http://web-access-root/, for instance: http://axnetworkmonitor/.
    • A Web View is visible by any mobile (touch) device or PC.
    Create a New View

    To Create a new View:

    • Start the ActiveXperts Web Access Configuration Tool from the Manager.
      To do so, Open Web Access from the Tools menu and select Web Access Configuration....
    • Press the Add View button. All web sites on the selected IIS server will be listed;
    • Select a Folder from the Folder Selection box;
    • The Default Filters will be applied. You can define additional Filters by clicking the Add View button.
    Configure a View

    To Configure a new View:

    • Start the ActiveXperts Web Access Configuration Tool from the Manager;
    • Select the View and press the Configure View button.

    8.5. Web View Access Control

    Controlling access to your ActiveXperts Web Views is crucial for hosting ActiveXperts Web Access. With Windows and the security features in IIS, you can effectively control how users access your Web Views, granting/denying access to particular Views.

    For example, enabling Anonymous access for all pages of ActiveXperts Web Access will allow any users to see what's happening on the Network. In most cases this is not acceptable.

    How Access Control Works

    You can control user access to your Web server content by properly configuring your Windows file system and Web server security features. When a user attempts to access your Web server, the server carries out several access control processes to identify the user and determine the allowed level of access.

    The following is an outline of the process:

    • The client requests a Web View on the IIS server;
    • The IIS server, if configured to require it, will request authentication information from the client.
    • The browser may either prompt the user for a user name and password, or offer this information automatically;
    • IIS checks if the user has a valid Windows user account. If the user does not, then the request fails, and the user gets a "403 Access Forbidden" message;
    • IIS checks if the user has Web permissions for the requested Web View. If the user does not, then the request fails, and the user gets a "403 Access Forbidden" message.
    How to configure Access Control

    Internet Information Services relies on NTFS permissions for securing individual files and directories from unauthorized access. You can use NTFS permissions to precisely define which users can access your content and how those users are allowed to manipulate that content.

    ActiveXperts recommends the following NTFS permissions on the root of the Web Access folder and all sub folders. This is by default: C:\ProgramData\ActiveXperts\Network Monitor\WebRoot\).

    • SYSTEM: Full Control
    • AXSERVER\Administrators: Full Control
    • AXSERVER\Users: Read
    • AXSERVER\Guests: No Access

    To prevents users from preventing access to specific Folder except one group, set the following permissions on that Folder:

    • SYSTEM: Full Control
    • AXSERVER\Administrators: Full Control
    • AXSERVER\GROUP: Read

    For instance yo prevents users from preventing access to Folder 1005 except group Support, set the following permissions on folder C:\ProgramData\ActiveXperts\Network Monitor\WebRoot\1005\:

    • SYSTEM: Full Control
    • AXSERVER\Administrators: Full Control
    • AXSERVER\Support: Read

    8.6. Web View Refresh Rate

    Client Browser Refresh Interval

    Client devices refresh their Views in order to update data provided by the ActiveXperts Netowrk Monitor Service. For each View, you can configure the Client Browser Refresh Interval (seconds). The default is set to 10 seconds.

    If there are many check in a Folder, or if Check intervals are configured execute only once an hour or so, a user may prefer to have the frequency less frequent. Imagine a user is monitoring a Folder with only Temperature checks; updating once every 2 minutes would suffice.

    Server Refresh Interval

    The ActiveXperts Netowrk Monitor Service provides data for Client devices. This is done once every 10 seconds by default. This value can be changed. Having a lower freqeuncy rate will offload the Engine's CPU and Disk activity.

    A confugration with only Ping checks may need a more frequent interval rate (e.g. once every 5 seconds) because usually, Ping checks run at a frequent rate producing different Ping reply times.

    On the other hand, confugration with only Temperature checks may need a less frequent interval rate (e.g. once every 5 minutes) .

    8.7. Customize Layout

    ActiveXerts Web Access can be fully customized. The master files are located in the following folder:
    C:\ProgramData\ActiveXperts\Network Monitor\WebRoot\_template\

    To customize the layout, you should make changes ONLY in the above _template folder.

    The following folders in the _template folder are relevant for customization:

    • folder - this Folder contains the List-view list.html file and Heatmap map.html file used in all Web Views.
    • index - this Folder contains the 3 possible index files used in the root of Web Access:
      * index-webviewsdisabled.html - index page when Web Access is disabled
      * index-webviewsvcnotrunning.html - index page when Web Access is enabled but the ActiveXperts service is not running
      * index-webviewsenabled.html - index page when Web Access is enabled and running. There's a special placeholder named $LISTSECTION that wil be replaced by the actual index information.
    • libs - this Folder contains several Javascript and CSS files. Most important for customization is the libs\activexperts\css\style.css file, which contains styling definitions for all pages.

    After the changes are made in the _template folder, you should manually delete ALL files and folders in the C:\ProgramData\ActiveXperts\Network Monitor\WebRoot\ folder EXCEPT the _template folder.
    After that, the ActiveXperts Network Monitor service will regenerate the live Web Access folders and files, based on the files located in the _template folder.

    In case you messed up your _template folder, or you cannot get bugs resolved, you can manually delete the _template folder. It will then and be restored automatically by he ActiveXperts Network Monitor service (factory default).

    9. Reports

    9.1. Introduction

    With the ActiveXperts Report Generator, users can create virtually any report. Reports can either be created using a Wizard, or can be generated by a Windows 'Task Scheduler' task without user interaction, which will generate them automatically, periodically (e.g. daily, weekly, monthly). If a report is run from a schedule, the actual report(s) can be sent automatically to a list of e-mail recipients.

    Report Data is stored in a database called the Statistical Database. This database also stores the Graph Data
    To read more about the Statistical Database, see topic Logging Statistical Data

    ActiveXperts Reports features the following:

    • Availability Reports. These reports contain reports aggregate fields, such as total up-time, total down-time etc. Aggregate fields are shown as absolute values (e.g. days, hours, minutes) as well as relative (percentage) values;
    • Incident Reports. These reports show all status changes, including reason for the status change and amount of time it remained in that particular status;
    • Filters - Filters ensure that your reports only return the data you require. The filters available are date/time, checks, folders and results;
    • Create reports interactive through a Windows Wizard (AxRgGui.exe);
    • Create reports from the Windows Task Scheduler using the Report Generator Command-Line Tool (AxRgCmd.exe);
    • Send Reports an an e-mail attachment;
    • Define custom Report Templates;
    • Supported Report formats:PDF, XML, HTML and CSV;

    9.2. Create a Report

    Step 1: Launch the Report Generator Wizard

    You can launch the ActiveXperts Report Generator from the Manager.
    To do so, Open Reports and Graphs from the Tools menu and select Create New Report.

    Step 2: Select a Report Definition File

    Select a Report Definition (.rep) file. A definition file includes all properties of the new report, including type of report, formartting, timeframe, filters and more.

    Step 3: Finish

    Press Finish to create the report. The report is saved in the Reports folder; in a default installation, it is located in folder:
    C:\ProgramData\ActiveXperts\Network Monitor\Stats\
    A Log file is created in the Logs folder; in a default installation, it is located in folder:
    C:\ProgramData\ActiveXperts\Network Monitor\Logs\

    Additionally, you can send the report to the e-mail recipients; the check box is only enabled if the Report Definition file contains e-mail recipients.

    9.3. Create a Report (scheduled)

    The ActiveXperts Reports allows you to send out reports automatically to a specified list of e-mail recipients. This can be useful for scheduled reports, for instance for reports that run automatically every week or every month.

    Step 1 - Configure a Report Definition file with e-mail recipients

    To send a report to e-mail recipients from a scheduled job, you must configure the e-mail recipients in the Report Definition (.rep) file.

    ActiveXperts Reports uses the same global e-mail settings as the ActiveXperts Network Monitor Manager and the ActiveXperts Network Monitor Service, like: SMTP server, fallback SMTP server (if any), SMTP login credentials (if any), E-mail Address Book, etc. To change global e-mail settings, you must use the ActiveXperts Network Monitor Manager.

    To configure e-mail recipients for a Report Definition (.rep) file:

    • Start the ActiveXperts Report Configuration Tool from the Manager.
      To do so, Open Reports and Graphs from the Tools menu and select Reports and Graphs Configuration....
    • Select the Reports tab;
    • Select a Report Definition File from the list, and press the Edit Selected button;
    • Select the E-mail properties sheet;
    • Select the E-mail report checkbox. You can now edit the e-mail subject and e-mail body, and select the e-mail recipients.

    NOTE: It is recommended to use E-mail Distribution Groups (from the E-mail Address Book) rather than individual recipients. With a Distribution Group, you don't need to change the Report Definition file to add/remove a recipient. You just need to modify the Distribution Group's recipient list. Besides that, a Distribution Group can be used by multiple Report Definition files.

    Step 2 - Create a test report from the command line (AxRgCmd.exe)

    Before you schedule a report using the Task Scheduler, it is recommended to test the report using the command line tool AxRgCmd.exe. This command line tool produces the same result as the graphical report tool (AxRgGui.exe) described in Chapter 7.2, but does not require any user intervention so it can be run from the Task Scheduler.

    To create a new report from the command line:

    • Start a new Command Prompt. You can start the prompt by pointing to Run in the Start menu, and type: CMD.EXE You can also start a new prompt pointing to Accessories from the All Programs menu, and then select Command Prompt.
    • Change the current directory; set it to the network monitor installation directory. For instance:
      CD "C:\Program Files\ActiveXperts\Network Monitor\"
    • Start the command line program to create a new report. It requires one parameter: the Report Definition File to be used to create the new report. For instance:
      AxRgCmd.exe /f detail-today-pdf.rep
    • The command line utility will create the report file. The output filename is specified in the Report Definition File. The results of the operations are logged in the following file:
      \Logs\ReportGenerator.log
    Step 3 - Schedule a Report using the Task Scheduler

    Report creation can be automated by scheduling the creation of a report using the Windows Task Scheduler. Scheduling is often used to create monthly reports and send the report to a specified list of e-mail recipients.

    With the Task Scheduler, you can only run the command-line version of the Report Creation Tool (AXRGCMD.EXE). The graphical version (AxRgGui.exe) requires user input and is not designed to run from the Task Scheduler.

    'Step 3' already described how to use the AxRgCmd.exe tool command line tool. This tool can be used to create a report from the command line using a Report Definition (.rep) file, without user intervention, like this:

    @echo off
    CD "C:\Program Files\ActiveXperts\Network Monitor\Program"
    AXRGCMD.EXE /f "detail-today-pdf.rep"

    Or (similar)

    @echo off
    CD "C:\Program Files\ActiveXperts\Network Monitor\Program"
    "C:\Program Files\ActiveXperts\Network Monitor\Program\AXRGCMD.EXE" /f "incident-today-pdf.rep"

    For scheduled tasks, it is recommended to make use of a batch file to encapsulate parameters. For instance, see:
    C:\Program Files\ActiveXperts\Network Monitor\Report Definitions\BatchJobs\Incident-Day.cmd

    9.4. Report Definition Files (*.rep)

    The properties of a report is described in a Report Definition file (.rep) file. This definition file describes the properties of a report, including:

    • Report Type; this can be either a Incident Report or an Availability Report. A 'Incident Report' shows all status changes and time the checks had a particular status; an 'Availability Report' provides overall availability information of the checks;
    • Report output file. Use placeholders to use dynamic report file names;
    • Time Frame. Date range, like: today, this month, last 4 weeks, etc.
    • Output format. Supported output formats are: PDF, HTML, XML, XML/XSL and CSV;
    • Filters. Filter on Checks, Folders, Check Types, and Results;
    • E-mail recipients. Recipient who should receive the report via e-mail.

    You can manage Report Definition file (.rep) files, use the ActiveXperts Report Configuration Tool. You can start this application from the 'ActiveXperts Network Monitor Manager':

    • On the Tools menu, click Reports and Graphs and click on the the Reports and Graphs Configuration Tool;
    • Select the Reports tab.
    ActiveXperts Network Monitor provides a set of pre-defined Report Definition files that can be used to create new reports:

    • Availability-month.rep
    • Availability-previousmonth.rep
    • Availability-today-html.rep
    • Availability-today.rep
    • Availability-yesterday.rep
    • Incident-month.rep
    • Incident-previousmonth.rep
    • Incident-today-html.rep
    • Incident-today.rep
    • Incident-yesterday.rep

    9.5. Customizing Reports

    To create/modify a Report Definition File, start the ActiveXperts Reports and Graphs Configuration Tool and do the following:

    • Select the Reports tab;
    • To create a new Report Definition File, click on the Create New button;
    • To modify an existing Report Definition File, select a Report Definition File from the list box and press the Edit Selected button;
    • When your create or edit a report, a wizard starts. It will prompt you for all necessary info.
    Availability Reports vs. Incident Reports

    On of the configurable items in a Report Definition File is the type of report. There are two types:

    • Availability Report;
    • Incident Report.

    An Availability Report provides overall availability information of your servers/checks during the nominated date range. You can see uptimes and downtimes, in days, hours, minutes and seconds, and also as percentages. An 'Availability Report' is used for instance to compare real availability statistics against the SLA requirements.

    A Incident Report provides a detailed list of all status changes during the nominated date range. For each check, you can see exactly when and why it failed, and for how long.

    Output filename

    On of the configurable items in a Report Definition File is the report output filename.

    You can choose for:

    • Fixed filename - a fixed filename, without placeholders;
    • Dynamic filename - a variable filename. It has year/month/day placeholder, so its name depends on the date when the report is created.

    On of the configurable items in a Report Definition File is the report output filename. If you use scheduled day/week/month/quarter/year reports, it is recommended to use dynamic filenames. Otherwise, new report files will automatically overwrite olders ones, because the report output files have identical names.

    With dynamic files, the name of the report file depends on the date it is created. You can use the following placeholders:

    • DD - day notation with leading zero
    • D - day notation without leading zero
    • MM - month notation with leading zero
    • M - month notation without leading zero
    • YYYY - year notation
    • YYY - year notation (3 digits only)
    • YY - year notation (2 digits only)
    • Y - year notation (1 digit only)
    Filename:    IncidentReport%MMDDYY%.xml
    Date of creation:  20180422
    Result:      IncidentReport042218.xml
    
    Filename:    IncidentReport%YYYYMMDD%.xml
    Date of creation:  20180422
    Result:      IncidentReport20180422.xml
    
    Report Output format

    One of the configurable items in a Report Definition File is the report output format. ActiveXperts Network Monitor supports four different output formats:

    • PDF;
    • HTML;
    • XML;
    • CSV.
    Timeframe

    On of the configurable items in a Report Definition File is the Start Date and the Start Date of a report. You can select the absolute Start Date and End Date, but it is recommended to use a relative Start Date and End Date. For example

    • This Day;
    • Previous Week;
    • Previous 5 Months;
    Filters

    You can define filters in your Report Definition File to show only a subset of all checks in your reports. You can define the following filters:

    • Checks - include all check in your report, or only a subset of all checks;
    • Check Types - include all kinds of checks, or only a subset. You can for instance create a report that only contains ICMP and HTTP checks;
    • Result - include only checks that have a specified result. For instance you can create a report of all checks with result: failed.
    E-mail

    The 'ActiveXperts Reports Generator' allows you to send out reports automatically to a nominated list of e-mail recipiuents. This is particularly useful for automated reports, where reports are created daily/weekly/monthly, automatically. Recipients are automatically notified of a new report. They just need to click on the URL that is inside the e-mail message.

    The 'ActiveXperts Reports Generator' makes use of the SMTP settings and E-mail address book of the ActiveXperts Network Monitor configuration. So, it uses the same primary- and secundary SMTP server as used by the ActiveXperts Network Monitor service. You can use the same e-mail distribution groups as used for e-mail alerts.

    9.6. Formatting Reports

    The PDF and HTML reports are based on an XSL stylesheet to format the report. With the PDF/HTML report, the stylesheet is used to create the report. Once the report has been created, you cannot change the format of the generated report. With XML based reports, a link to the XSL stylesheet is included in the XML report. This means that report data and formatting are stored in two separate file, so you can change the format of the XML report at any time.

    XML Report Data

    Appx D. Report Definition XML Tags describes the Report Data of the XML files.

    XSL

    The 'ActiveXperts Reports Generator' allows you to send out reports automatically to a nominated list

    By default, all PDF/HTML 'detail' reports are based on the following XSL stylesheet:
    IncidentReport.xsl

    All PDF/HTML 'availability' reports are based on the following XSL stylesheet:
    AvailabilityReport.xsl

    To change the format of a report, you can either modify the XSL file, or create a new custom XSL file and link the reports to the new XSL file.

    To create a new XSL file:

    • Start the Windows Explorer;
    • Point to the \Report Definitions\StyleSheets\ directory;
    • Make a copy of an existing XSL sheet.

    To link a report to a new custom XSL file:

    • Start the ActiveXperts Reports and Graphs Configuration Tool;
    • Select the Reports tab, select the Report Definition File and press the Edit button;
    • In the Report Output tab, select a new XSL file. XSL files are located in the \Report Definitions\StyleSheets\ folder.

    To modify an XSL file:

    • Start the Windows Explorer;
    • Point to the \Report Definitions\StyleSheets\ directory;
    • Select an XSL file and choose Edit from the context menu.

    To change the format of an HTML or XML report requires basic knowledge of XSL. A good tutorial to XSL can be found here: www.w3schools.com.

    Basic XSL statements

    Use the <xsl:for-each> tag to iterate over a set of checks.

    <xsl:for-each select="monitor/check">
        ...
        <br><xsl:value-of select="result"/><br>
    </xsl:for-each>
    
    The XSL <xsl:for-each> element can be used to select every XML element of a specified node set. 
    The <xsl:value-of> element can be used to select the value of an XML element and add it to the 
    output stream of the transformation.
    

    Use the <xsl:sort> tag to sort a record set.

    <xsl:for-each select="monitor/check">
    <xsl:sort select="result"/>
    <xsl:sort select="displayname"/>
        ...
    <xsl:for-each>
    
    To sort output it at the same time, simply add the <xsl:sort> sort element inside the for-each 
    element in your XSL file. Use multiple <xsl:sort> elements to sort on multiple columns.
    

    Use the <xsl:if> tag to use a condition.

    <xsl:if test="result > 2">
      ...
    </xsl:if>
    
    To put a conditional if test against the content of the file, simply add an <xsl:if> element 
    to your XSL document. The value of the required test attribute contains the expression to 
    be evaluated.
    

    Appx D. Report Definition XML Tags describes the XML tags that can be used in the report definition stylesheets (.xsl).

    10. Graphs

    10.1. Introduction

    With the ActiveXperts Graphs tool, users can create graphs for any Check. You can have multiple Graphs in one screen for multiple Checks, with the restriction that the Checks must be of the same check type (e.g., all ICMP).
    Graphs are created from the Manager using the Check's context menu. Simply right-click on a check, and the Graphs option will appear.

    Graph Data is stored in a database called the Statistical Database. This database also stores the Report Data
    To read more about the Statistical Database, see topic Logging Statistical Data

    ActiveXperts Graphs features the following:

    • Show Graphs of single or multiple Checks in one Window. Checks must be of same check type.
    • Define any Time Frame. You can create Graphs of any start date and end date in history;
    • Zoom feature, to zoom in and out;
    • Save the Graph(s) in various formats including PDF, PNG and JPG;

    10.2. Creating a Graph

    Step 1: Use the ActiveXperts Network Monitor Manager

    Launch the ActiveXperts Network Monitor Manager.

    Step 2: Select one or multiple Checks

    Select a single Check, or select multiple Checks of the same check type.

    Step 3: Launch the Graph tool from the context menu

    Right-click on the selected Check(s), and choose Show Graph....

    11. Operators and Roles

    11.1. Introduction

    Access to the configuration of ActiveXperts Network Monitor is controlled by Operator Roles. Allow full control to any user on all configuration aspects, or allow only predefined operators to access the configuration and associate permissions to those operators.

    The Microsoft SQL Compact Database Config.sdf file holds ALL the configuration data. In a default installation, it is located in folder:
    C:\ProgramData\ActiveXperts\Network Monitor\Configuration\
    Permissions that Operators have on aspects of the configuration are also stored in this file.

    11.2. Administrator permissions to all

    By default, all users with a valid Windows login on the ActiveXperts Network Monitor server have 'Full Administrator' permissions. This means that they can make any changes to the ActiveXperts Network Monitor configuration. However, if you want to limit permissions to users, you can assign an Operator Role to each individual.

    11.3. Operator Roles

    If you don't want 'Full Administrator' permissions to all users of Network Monitor, you need to select the Active Directory users that you want to grant access to the Network Monitor configuration. To each user, an Operator Role must be assigned.

    A Windows user account can be assigned one of the following Operator Roles:

    • Full Administrator - Manage Operators; Full Access to all Global Settings and all Checks
    • Advanced Operator - Full Access to all Global Settings and all Checks
    • Operator - Read-Only access to all Global Settings; Full access to all Checks
    • Read-Only Operator - Read-Only access to all Global Settings; Read-Only to all Checks
    • No Access - No access to the configuration.

    11.4. Configure Operator Roles

    As mentioned, all users with a valid Windows login on the ActiveXperts Network Monitor server have 'Full Administrator' permissions by default. To have different Operator Rules for operators, you must first enable this option:

    • From the Tools menu, choose Options;
    • Select the Operator and Roles tab;
    • Select the option Only allow predefined Operators to manage ActiveXperts Network Monitor.

    You can associate 'Operator Roles' to one or more Windows accounts. Do do so:

    • Click on the Select from Domain;
    • In the Domain field, enter your domain and press the List Users button;
    • Select one or more Domain users, and select an Operator Role; then press the Select button Role.

    NOTE: You can also enter a valid hostname in the Domain field, in case you want to select local user accounts.

    12. Dependencies

    12.1. About Dependencies

    Dependencies allow you to create a hierarchy of Checks that depend on each other. This hierarchy is independent of the Folder structure of your Network Monitor configuration.

    Dependencies prevent you and your network administrators from being overwhelmed with alert notifications when a central router or server goes down. Without a dependency configuration, the failure of a central server or device would cause a failure of other servers, and as a result many alert notifications would be sent out.

    A dependency will not stop the monitoring of a Check or a set of Checks as soon as a specific Check is in Failure status; it will continue monitoring, but it will show a different status: Dependency Failure, with a orange icon. In Reports and Graphs, the status will also be 'Dependency Failure'.

    There are at least two items involved when configuring dependencies:

    1. Dependee - the server or device that plays a central role. A failure of this 'dependee' device or server would cause failures of other servers and devices (so called 'dependers');
    2. Depender(s) - servers, devices or folders that depend on the 'dependee'.

    There's more information on Dependencies on the ActiveXperts Web Site: activexperts.com/support/network-monitor/online/dependencies. There's a sample included to illustrate how dependencies should be used.

    13. Maintenance

    13.1. Introduction

    Usually there are planned periods of time during which systems undergo maintenance activities that can cause service disruption. During such periods, you don't want Alert Notifications to be generated and Alert Actions to be executed. In addition, you wouldn't like such periods to be taken into account when calculating the Availability report information of your system.

    To avoid such situations, ActiveXperts enables you to define maintenance windows. ActiveXperts enables you to define Maintenance Plans, each one having one or more time schedules. These Maintenance Plans can be assigned to Checks. All Maintenance Plans are managed globally.

    13.2. Configure Maintenance Plans

    In ActiveXperts, there's a default Maintenance Plan that is assigned to a Check when it is created. If you do not have any maintenance activity in your network, you can can have zero schedules assigned to this maintenance plan. Otherwise, configre one or more schedules.

    If you have servers, or groups of servers that need a different maintenance window that the default Maintenance Plan, you can create new Maintenance Plans that you can assign to Checks.

    Configure your Maintenance Plans in the Maintenance tab of the Options menu.

    Create a new Maintenance Plan

    To create a new Maintenance Plan, choose Create New maintenance Plan from the Configure Maintenance Plan tab drop-down box.

    Rename / Delete a Maintenance Plan

    To delete a new Maintenance Plan, select the Maintenance Plan that you want to rename/delete and choose Rename/Delete Maintenance Plan from the Configure Maintenance Plan tab drop-down box.

    Configure a Maintenance Plan

    To configure a new Maintenance Plan, select the Maintenance Plan from the Configure Maintenance Plan tab drop-down box. You can then Add, Remove and Configure zero or more Maintenance Schedules for a Maintenance Plan.

    Maintenance Schedule

    A Maintenance Plan consists of zero or more Maintenance Schedules. No schedules means that there's no maintenance activity defined. A Maintenance schedule can be recurring (once every monday, tuesday, etc), or can be set as one particular date. Furthermore, a maintenance schedule has a time and a fixed number of hours the system will undergo maintenance.

    14. Data Logging

    14.1. Introduction

    ActiveXperts Network Monitor has three diffferent types of Logging:

    1. Statistical Data Logging - Used for statistical purposes, to allow the ActiveXperts statistical tools to produce Reports and Graphs;
    2. Application Logging - To see a history of all operations of the Engine;
    3. Real-Time Activity Logging - To view real-time Activity of the Engine in the ActiveXperts Network Monitor Manager

    This Chapter explains these three Logging topics.

    14.2. Statistical Data Logging

    ActiveXperts Reports and ActiveXperts Graphs make use a database called the Statistical Database. By default, this is an MS SQL Compact Database file named Stats.sdf. In a default installation, it is located in folder:
    C:\ProgramData\ActiveXperts\Network Monitor\Stats\

    The Engine stores data in this database frequent. This data is used by the both Report and Graph programs to produce the reports and graphs by the use of advanced queries on the Statistical Database.
    There are two tables involved in this Statistical Database:

    • ReportData - used for creating Reports
    • GraphData- used for creating Graphs

    The Engine inserts an entry in the ReportData table for each status change of a check. Every 5 minutes, the entry is updated to store the last monitored date/time stamp. As soon as there's a status change, a new entry is written.
    If you want, you can change this value through the registry. See FAQ item #Q7780030.

    The Engine inserts an entry in the Graph table for each status change of a check, and once every 5 minutes by default. If you want the Engine to write more frequent to have a more accurate Graph, use the ActiveXperts Reports and Graphs Configuration Tool:

    • From the Manager application, choose Tools and select the Reports and Graphs Configuration Tool;
    • Select the Graphs tab, and change the value in field Once every x minutes.
    Statistical Data Migration

    It is strongly recommended to migrate the MS SQL Server Compact Database Stats.sdf database to either MS SQL Server or MySQL server, to boost the performance of the creation of reports and graphs.
    MS SQL Server Compact Database is an embedded database; MS SQL Server and MySQL are server-side relational databases. Server-side relational databases are installed as an independent service and run outside of the scope of the ActiveXperts application. That is why they can perform much better because of the intrinsic support for multi-core and multi-CPU architectures, using OS features like pre-caching.

    Migration is easy and seemless; use the ActiveXperts Reports and Graphs Configuration Tool:

    • From the Manager application, choose Tools and select the Reports and Graphs Configuration Tool;
    • Select the Statistical Database tab, and press the Migrate button.
    • A Wizard will guide you through the steps of migrating all Statistical Data to either MS SQL or MySQL. All datastructures will we created, including tables, indices and relationships.

    14.3. Application Logging

    All operations of the ActiveXperts Network Monitor Service (the 'Engine) are logged, to allow administrators to see what happened exactly in the past. The following activities are logged:

    • Monitoring activities
    • Other activities, like Alerts ( e.g. e-mail alerts, SMS alerts), Actions (e.g. a computer restart, a service restart, a custom script execution) and important system information.
    Log to a Plain Text File

    The Log information is stored by default in a text file named Log.txt. In a default installation, it is located in folder:
    C:\ProgramData\ActiveXperts\Network Monitor\Logs\

    The Log.txt file has a configurable maximum size limit. After the limit has exceeded, the Log.txt file is copied to Log00001.txt and a new Log.txt is used. After the log is full, it will be copied to Log00002.txt, etc.

    To change the Log.txt file size limit, use ActiveXperts Network Monitor Manager and do the following:

    • Select Options from the Tools menu. The first tab you see is named Logging;
    • Press the Advanced Log to Text Settings button and change the maximum file size.
    Log to a Database

    Logging to a Plain Text file is the most used option. However, if you prefer to have data logged in a database, you have three choises: MS SQL Compact Database, MS SQL Server database, or a MySQL database.

    To change logging from Plain Text to a database, use the ActiveXperts Network Monitor Manager and do the following:

    • Select Options from the Tools menu. The first tab you see is named Logging;
    • Select the option Log to a Database. It will have the proper connection string to Log.sdf database that ships with the software.
    Application Data Migration

    Once using the MS SQL Server Compact Database Log.sdf, you can migrate it to either MS SQL Server or MySQL if you prefer. However, it will not boost performance like it does with the Statistical Database, because there are no complex queries involved.

    Migration is easy and seemless:

    • From the Manager application, choose Tools and select Options;
    • Select the Statistical Database tab, and press the Migrate button
    • A Wizard will guide you through the steps of migrating all Statistical Data to either MS SQL or MySQL. All datastructures will we created, including tables, indices and relationships.

    14.4. Real-Time activity Logging

    The ActiveXperts Network Monitor Manager has a Real-Time Activity View on the bottom of the screen. This shows the most recent activities of the Engine. The Real-Time Activity View has of the following tabs:

    • Activity/System - this shows system information, like database operations, license key information, and more;
    • Alerting/Actions - this shows Alerts (e.g. e-mail, SMS) and Actions (e.g. restart of a computer, restart of a server, execution of a custom script)
    • Monitoring (All) - this shows all monitoring activities
    • Monitoring (Error/Failed) - this shows all monitoring activities which checks failed
    • Monitoring (Uncertain) - this shows all monitoring activities which checks were Uncertain

    The Real-Time Activity View doesn't use any of the log files described earlier; it has its own internal temporary log files. In a default installation, it is located in:
    C:\ProgramData\ActiveXperts\Network Monitor\Logs\Ipc\Activity

    The above folder location is in fixed location, and cannot be changed. The log files are cleaned periodically, to boost performance.
    You can change the number of entries that you want to see in the view. To do so:

    • From the Manager application, right-click in the Real-Time activity view of the ActiveXperts Network Monitor Manager and change the number of entries.

    15. Tuning the System

    15.1. Introduction

    The ActiveXperts Network Monitor Service (the Engine) monitors servers, workstations and devices from a central point. It is designed to run multiple checks simultaneously. To do so, it uses multiple sub-processes, so-called threads. Multi-threading gives a program the ability to perform many tasks simulteneously.

    In ActiveXperts Network Monitor, multiple threads are spawned, including:

    • Dispatcher - holds the configuration of the software. It has a queue of checks and decides which checks need to be checked. It determines which threads are busy and which threads are not, and passes a check to a thread that is capable of handling that type of check;
    • Notifications - Notifications can be time consuming, and are therefore assigned to threads to do its job. For instance, an SMS message through an SMSC dial-up provider can take up to 90 seconds. A NetPopup notification message to a non-existing NetBIOS recipient can take up to 10 seconds;
    • Checks - There are many threads for different types of checks, to optimize ActiveXperts Network Monitor's monitoring performance. There are threads for ICMP checks, CPU checks, Database checks, etc.

    The number of threads has a strong influence on the performance of the ActiveXperts Network Monitor Engine (service). If there are only a few threads, the software will not use much CPU and memory resources, but the throughput of checks may be low. By increasing the number of threads, the throughput will increase. However, too many threads will consume too many system resources together (each thread consumes memory and CPU), decreasing the performance of the Network Monitoring engine dramatically.

    15.2. Configuring Threads

    To configure the number of threads:

    • From the Manager application, choose Options from the Tools menu;
    • Select the Performance tab;

    In the Performance tab, you find all different types of threads. You can change the number of threads that are spawned when the ActiveXperts Network Monitor is started. As a result, changes take affect after you restart the service!

    The following threads are used by the ActiveXperts Network Monitor Service (Engine):

    • Environmental - handles environmental related checks: 'Temperature', 'Humidity' and 'Wetness'. Default number of threads: 1.
    • FTP - handles 'FTP' and 'TFTP' checks. Default number of threads: 1;
    • HTTP(s) - handles 'HTTP/HTTPs' checks. Default number of threads: 4;
    • ICMP/Ping - Handles 'ICMP/Ping' checks. Default number of threads: 8;
    • OLE Database - handles generic 'Database' checks, including checks for MySQL and MS SQL. Default number of threads: 2;
    • Oracle - handles 'Oracle' checks. Default number of threads: 1. IMPORTANT: you can configure only 1 Oracle thread;
    • PowerShell - handling (custom) PowerShell based checks. Default number of threads: 2.
    • Remote Command - handles Remote Command checks. Default number of threads: 1.
    • Removable Drives - handles Removable Drives checks. Default number of threads: 1.
    • Serial Communications - handles 'Serial Device' checks. Default number of threads: 1;
    • SMTP/POP3 - handles 'SMTP' and POP3' checks. Default number of threads: 1;
    • SMTP/POP3 (RR) - handles 'SMTP to POP3' Round-Robin checks. Default number of threads: 1;
    • SNMP Trap - handles 'SNMP Trap Receive' checks. Default number of threads: 1;
    • Socket - handles the following checks: 'TCP', 'ICA', 'DHCP', 'RSH', 'SNMP GET', 'NNTP', 'NTP', 'DNS', 'RADIUS' and 'TraceRoute'. Default number of Socket threads: 6;
    • SSH - handles 'SSH' checks. Default number of threads: 4;
    • SFTP - handles 'SFTP' checks. Default number of threads: 1;
    • VBScript - handles (custom) VBScript-based checks. Default number of threads: 4;
    • Virtualization - handles the following checks: 'VMware', 'XenServer', 'Hyper-V' and 'Verde VDI'. Default number of threads: 4;
    • Win32 - handles the following checks: 'Directory Size', 'Scheduled Task for NT4' and 'File'. Default number of threads: 4;
    • WinUpdate - handles the following checks: 'Windows Update'. Default number of threads: 2;
    • WMI - handles all WMI based checks, e.g. 'Anti-Virus', 'Active Directory', 'Disk Space', 'Hyper-V', 'CPU', 'Disk Drives', 'Event Log', 'Memory', 'MS BizTalk Server', 'MS Exchange Server', 'MS IIS Server', 'MS Index Server', 'MS ISA Server', 'MS Message Queue', 'MS SharePoint Server', 'MS Performance Counter', 'MS Terminal Server', 'Printer', 'Process', 'Scheduled Task', 'Service' and 'Windows Defender'. Default number of WMI threads: 8.

    15.3. Log files

    ActiveXperts Network Monitor maintains its own Application Log Files. Applicion Logging is enabled by default. In a default installation, it is located in folder:
    C:\ProgramData\ActiveXperts\Network Monitor\Logs

    There more information about Application Logging, see topic Application Logging.
