ActiveXperts Network Monitor ships with a large collection of WMI based PowerShell scripts and VBScript scripts to monitor and manage a network.

Use ActiveXperts Netork Monitor to monitor your virtualization servers, domains, computers and devices. It runs on a single Windows server, without agents required on the monitored systems. It has many built-in checks and also allows administrators to create custom checks using PowerShell, VBScript, WMI and SSH.

Win32_PerfRawData_PerfOS_Processor - WMI sample in Perl

The foundations for Manageability in Windows 7/2008/Vista/XP/2000 and Millennium Edition/'98 are Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).

ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself.

On this site, you can find many WMI samples.


Win32_PerfRawData_PerfOS_Processor

Description

The Win32_PerfFormattedData_PerfOS_Processor "cooked" data performance counter class represents calculated counters that measure aspects of processor activity. The processor is the part of the computer that performs arithmetic and logical computations, initiates operations on peripherals, and runs the threads of processes. A computer can have multiple processors. The processor object represents each processor as an instance of the object. This class is shown as the Processor object in System Monitor. The WMI source of its data is the high-performance Cooked Counter Provider. This class derives its raw data from the corresponding raw class Win32_PerfRawData_PerfOS_Processor. The original data source is the PerfOS performance library. This class was added for Windows XP.
