Heads up: some issue I faced during recent CSM monitoring implementation. Working on remediation with Microsoft. Still, beware. While working on one of the recent consulting projects I faced a strange behavior dealing with CSM monitoring implementation. This article is written based on the hands on experience. As you know on 64-bit boxes in app pool configuration you can check to “Enable 32-Bit Applications” option. Say, for some reasons I had to enable it for CSMCollector app pool (“OperationsManagerCsmCollector v4.0”): Having done this I noticed that I started missing CSM data. Albeit the web application pages are injected with uX scripts, the requests are sent to CSMCollector (I can check this with Fiddler), but I get no client-side events and statistics received at all. I enabled APM trace log on affected server and got plenty of “CSMCollector ServiceManager is not active” errors like below: Agent version: 7.0.5000.0 .NET Framework: v4.0.30319.269 ProcessID: 30488; InstanceID: 0; InstanceName: w3wp.exe; ApplicationPool: OperationsManagerCsmCollector v4.0; Full Domain name: /LM/W3SVC/8/ROOT/CSMCollector-1-129917338260256050; [0]30488.21608::09/10/2012-02:57:03.248 [Agent.CSMCollectorService] [] [Error] :CsmCollectorService.ProcessCsmEvent{csmcollectorservice_cs257}( 015DF0E0 )CSMCollector ServiceManager is not active.

Looks like a bug. When I switch back and disable 32-bit apps for CSMCollector app pool, everything works pretty well. According to log most likely the problem deals with CSMCollector installation key search in registry. When you enable 32-bit applications on the pool, it might start looking for CSMCollector keys in 32-bit branch and cannot find it there, while actually it’s registered in 64-bit registry path. Still no resolution or workaround found for the issue. Probably it can be resolved only with code fix. Regards!
