    We developed an MP that uses SDK to create SCOM objects and insert a large number of performance counters ~ 2000 every 5 minute interval.

    On SCOM side the MP has about 2000 instances of UnitMonitor (only ~20 per class but there are lots of  actual objects). In these monitors we use 

    DataSource based on Microsoft.SystemCenter.TargetEntitySdkPerformanceDataProvider. All worked fine for a year but lately added a bunch of new objects/counters and CPU utilization for the MonitoringHost.exe started to spike to 100% a few seconds after the Performance Counters were posted via SDK. The spike lasts for up to 3 minutes. No DB or Network spikes observed. We suspect SCOM does not deal efficiently with SDK Performance data - as if a separate SdkPerformanceDataProvider is started for every UnitMonitor when the counters are posted rather than having cooked-down - one per Target instance.

    Can anyone shed some light on this? I suspect only the Microsoft engineers would know.

    Our environment is like this:

    • SCOM 2012 R2 UR4
    • Windows Server 2012 8 Core, 16 GB Ram

    Thanks,

    Dave

    Hi Dave,

    is there a way that you can reduce the number of performance insertions? Regardless of even fixing the performance issue, the impact from a database standpoint may be something to consider in the long term. My point is that fixing one issue, will take us to the next one, etc etc.

    I would reduce the number of insertions, only to the either insertion of the "most critical" or "top #". Also, aren't those counters already captured out of the box?
