Solaris 11 OperatingSystem Total Percent Processor Time Monitor

Knowledge Base article:

Summary

The total percentage of processor time (for all processors) is high. System performance may be adversely affected.

Total processor time is the time that all processors spent running a non-idle thread. Each processor has an idle thread that consumes cycles when no other threads are ready to run. This metric is the primary indicator of processor activity, and displays the average percentage of busy time observed.

The monitor threshold is analyzed against an average of values returned in polls to the agent, where the Number of Samples parameter controls the number of samples included in the calculation of the average. The value returned by the agent is the rolling average of the 5 most recent values queried at 1 minute intervals.

Default Value

Threshold

95

Interval (seconds)

300

Number of Samples

Overrides can be used to change the parameter values defined above for all instances or for specific instances or groups.

Causes

An unhealthy state indicates that the processor utilization is currently high. This may be caused by an application using excessive processor resources.

Resolutions

To address high processor time conditions choose one or more of the following options:
