JON platform process service resource's CPU Percentage metric value can be incorrect if monitored process is restarted or shutdown

Solution Verified - Updated -

Issue

  • Is Process resource metric value of CPU Percentage (CPU%) accurate?
  • I sometimes see high CPU utilization (6699.8%)
  • How is the CPU utilization percent captured?
  • CPU Percentage measurement's maximum value is much higher then possible

Environment

  • Red Hat JBoss Operations Network (ON) 3.2
  • Platform Process service resource in inventory
  • Process service resource's CPU Percentage metric is enabled for collection
  • CPU Percentage measurement value or its maximum value is reported many times higher then 100%
  • Process being monitored has been shutdown or restarted
