Situation Description

Percentage of time the processor is busy is extremely high.

 

Possible Causes
  1. High CPU usage might be caused by run-away processes.
  2. Intermittent hardware failures might also cause spikes in CPU usage.
  3. Unusually high workload (transactions) on the system.

 

Suggested Actions

A frequently low value for CPU in idle state indicates that the processor can be overloaded. Check for run-away processes, or any configuration changes that may have caused CPU usage to spike. Check /var/log/messages for signs of hardware failures. Finally, if it this is due to an increase in workload, consider upgrading the processor.
