Page Faults Alarm

This alarm is activated when the number of pages being swapped exceeds a threshold. Sustained high paging rates can adversely effect the performance of a system.

When this alarm is current, you should:

• Look at the Processes page on the Processes drilldown to see which process is causing the paging. Look at the Page Faults/sec column. This will help you determine the cause of paging.
• Look at the Paging chart on the Summary page of the Memory drilldown. This shows how long the high paging has been occurring. Short periods of high paging are acceptable, but if the paging rate is high for a sustained period, there may be a problem with the system.
• Consider adding more physical memory to the system.
• Stop unnecessary services and processes on the system.
