Monitoring Exchange SP1 with SCOM

Hello,

If you have noticed, some of you after applying SP1 will not be able to collect some performance data and get alerts as before, A some DB performance counters has been changed is SP1, this caused performance data not to be collected so here is what is going exactly. As far is reported the only performance counter object that was changed in SP1 was the Database object, which was renamed to the MSExchange Database object (affects mb, hub transport, edge transport roles). A list of where these counters appear is below.  the alerts customers could be missing would be the ones generated by the monitors. Obviously the views and data collection rules do not work either.

 

In terms of workarounds for this, you could disable the 2 rules and monitors and create a separate MP where the rules collect the “right” performance counters and the monitors take configuration from the rules. You’d need to do the proper targeting, but the MP classes are declared as public, so you could refer to them from another MP.

 

Note that for the updated MP, we will look for the updated (SP1) counters only, i.e. the customers could expect seeing similar types of behavior from their monitored Exchange 2007 RTM servers.
