WMI Samples - Exchange

ActiveXperts Network Monitor is an advanced and easy tool for monitoring LAN and WAN networks, network servers, workstations and TCP/IP devices. It has a large set of built-in checks, and you can add new checks by writing scripts. You can use VBScript (Windows) or RSH (UNIX) for it. VBScript checks can use WMI and ADSI. WMI is an interface to a broad range of properties of a computer/OS/application. With ADSI, you can monitor Directory Services.

Use the samples below to get used to various WMI classes, and use these classes in your own, custom ActiveXperts Network Monitor check. Each sample below can also be copied to a new file and then run from the command prompt (CSCRIPT.EXE <file>.vbs).

MSExchangeAL Performance Counter


The Recipient Update Service (RUS) plays a crucial role in the day-to-day operations of Exchange 2000 because it is responsible for keeping e-mail addresses and membership of address lists up to date. You should measure the Address List Queue Length when examining the RUS:
  • Address List Queue Length - shows the load the Recipient Update Service is under. If this value is consistently high compared to your baseline, you should seriously consider upgrading the server that has this role, or transferring the role from a weak or overloaded server to a more powerful one.

MSExchangeIS Performance Counter


For this object, monitor the following counters:
  • User Count – This displays the number of people currently using the Information Store (not the number of connections). It is impossible to properly judge the performance of a server running Exchange unless you know how many people are using it.
  • RPC Requests – This shows the number of client requests currently being processed by the store. You should expect this figure to be fairly small, typically below 25. If it is consistently higher than this, your server is overloaded.

MSExchangeISMailbox Performance Counter


MSExchangeIS Mailboxes and Public Folders:
  • Send Queue Size – This shows the queue of messages outbound from the Information Store. In situations where the SMTP service is down or there is a reduction in performance, you will see a nonzero value for this queue. On large busy systems (2000 users or more) you may never see this value at zero, but on smaller ones (500 or so medium users) you would not expect to see nonzero values for any significant period of time.
  • Messages Sent/Min – This shows the rate at which messages are sent to the transport. This figure being low is not a problem in itself, but if the Send Queue Size is nonzero and the value is still low compared to your baseline, then there are performance issues that need to be resolved (you will only be able to tell what these are by monitoring other Exchange 2000 Server and Windows 2000 counters);
  • Received Queue Size – This shows the queue of messages inbound to the Information Store. Unlike the Send Queue size, this is often nonzero, except on a bridgehead server with no local mailboxes. However, if the value is consistently high compared to your baseline, it could indicate a problem;
  • Messages Received/Min – Again a low value here could simply indicate a quiet server; however if the Receive Queue Size value is high and this value is low, it indicates that you are receiving messages that are stacking up and are not being processed.
