Processor Percent Processor Time

Microsoft.Linux.RHEL.6.Processor.PercentProcessorTime.Monitor (UnitMonitor)

Red Hat Enterprise Linux Server 6 Processor Percent Processor Time Monitor

Knowledge Base article:

Summary

This monitor checks the Percent Processor Time for each processor. If you receive an alert from this monitor, action can be required in order to bring the system back to an operational state.

The Percent Processor Time is the percentage of time the processor was busy during the sampling interval.

Causes

High processor-time values can occur under the following circumstances:

Resolutions

To address high percent processor times choose one or more of the following options:

You may view the Top CPU Consumers by executing the "Top 10 CPU Processes" Task from the State View.
