Tens MOMPerfSnapshotHelper.exe running on Win Srv 2008 SP2

Question

_{Thursday, July 7, 2016 11:02 AM}

Hi all!

I am experiencing for the first time this issue:
On a Win Srv 2008 SP2 I can see around 30 MOMPerfSnapshotHelper.exe processes running. Each one allocates from 1% to 3% of CPU. The total average is 60%. This is bad because allocates the greatest part of a opta-core server.
I stopped the SCOM 2012 SP1 Agent, cleaned the "Health Service State\Health Service Store" folder and also "Health Service State\Management Packs". None of the MOMPerfSnapshotHelper.exe has been closed. Of course then I started the Agent.
I read the KB https://support.microsoft.com/en-us/kb/2812950 but on the Win Srv 2008 SP2 there is NOT Microsoft SharePoint 2010 installed (actually there is not Microsoft SharePoint at all and of any versione) therefore I did not installed the patch.
I also tried to search for some other useful article about my issue but none of them is applicable (e.g.: related to SCE, etc.)

This thread https://social.technet.microsoft.com/Forums/systemcenter/en-US/f9edf415-1fe1-498d-8cf3-3103d4751c59/monitoringhostexe-high-cpu-usage-on-scom-r2?forum=operationsmanagergeneral does not help because is says "high CPU usage (98-99%) for MonitoringHost.exe" not "low CPU usage (1-3%) for several MonitoringHost.exe"

Have you some suggestion? Do you suggest to apply the patch of KB https://support.microsoft.com/en-us/kb/2812950 also if not having Share Point installed?

Than you for your help

Hi Sir,

>>Do you suggest to apply the patch of KB https://support.microsoft.com/en-us/kb/2812950 also if not having Share Point installed?

In my opinion , it is worth to try KB2812950 .

Because , it only stated  "This issue usually occurs " , but not must be cuased by Sharepoint.

The root cause is "When you use more than 64 V2 performance counters to collect system data" .

Best Regards,

Elton

Hi Elton and thank you for your reply.

Sorry for my late answer but I was on holidays.

Actually I agree with you answer. My concern was due to the sentence saying "[...] this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing the problem described in this article[...]" that literally conflicts with the meaning of word "usually" of sentence "This issue usually occurs[...]".

Anyway I will try install it and see what happens!

Thank you since now!

Hi!

Actually I could not try because my involved servers are Win 2008 R2 x64, while the patch is suitable only for Win 2008 (not R2)... :-(

Thank you anyway!

Bye!
