On some occasions the scom agent can cause a lot of performance issues on the servers. Here I will describe some steps I take when I have performance problems and in most of the cases it works for me.
The first thing you should do is to configure the antivirus exclusions for opsmgr. Have a look at Kevin Holman’s blogpost Antivirus Exclusions for MOM and OpsMgr on how to do this. Configuring anti virus exlusions will help you gain some performance.
This is a screenshot of the performance of my cpu before the anti virus exclusions:
And this one is after the anti virus exclusions:
The second thing is to have a look at the healthservice.exe. We’ve created a collection performance rule in the previous post to collect the processor time % of the healthservice. If the healthservice is consuming more than 15 a 20 % of your cpu you have a problem . In my case I had huge performance problems due to the healthservice.exe that was taking all the processor time. My healthservices.exe was taking about 50 to 60 % with peaks to 100% on my agents….You can imagine the reaction of my client….he was not very happy.
Performance view of my healthservice.exe on one of my agents:
So I did some tests, installed all the necessary hotfixes, deleted the healthservice cache, exception of programfilesscom for the antivirus etc etc. But with no results.
So I tought it was WMI and did the following steps to rebuild the wmi:
· Net Stop WinMgmt
· Ren %WinDir%System32WbemRepository %WinDir%System32WbemOldRepository
· Net Start WinMgmt
Still no success, still had performance troubles. I contacted one of our company architects who send me a repairwmi.cmd “program” he developed . It will recompile all the mofiles, re-register all the dll’s, exe’s etc.
Steps to take:
- Copy the content of the repairwmi.cmd to the %WinDir%System32Wbem folder</p>
Run the repairwmi.cmd
Stop the opsmgr healthservice
Delete the healthservice cache
- Start the opsmgr healthservice
And voila! All my performance problems where gone!!
As you can see this reduced drastically the processor time % of the healthservice!
Hope this helps,
