Need to understand, how the monitor "Total CPU Utilization Percentage" works in scom RRS feed

  • Hi,

    Jonathan also created a blog post based on the thread you've found, you'll find the blog post over here:
    How does the ‘Total CPU Utilization Percentage’ monitor work?

    By default the Total CPU Utilization Percentage is defined to a very high value, and it relies on multiple counters both CPU Usage and Queue over multiple samples (over 95% CPU Usage and over 15 CPU Queue Length over 3 samples).

    So in short:

    Total CPU Utilization Percentage will generate alert when both CPU utilization and Queue excess the threshold.


    Best regards,

  • Hi,

    We could also do the trick and set the queue length to -1 as below:

    We can configure the monitor to only use the % Processor Time threshold.  If the CPU Queue Length override parameter is set to -1, this will effectively change this monitor to an unhealthy state when only the % Processor Time threshold is exceeded, because the Processor Queue Length value will always be greater than -1.

    Hope the above information helps.
