Page Hits Alarm

This alarm is activated when the proportion of page requests that can be sourced from memory rather than disk drops below a threshold.

When this alarm is current you should:

• Look at the Paging chart in the Summary page of the Memory drilldown to see if a high level of paging has been occurring for an extended period. Spikes in requirements are expected.

• Look at the Page Faults/sec column on the Processes page in the Processes drilldown.

  This will tell you which applications are making the most page requests. If this is an ongoing problem, look at spreading the load between multiple systems.

• Look at increasing the physical memory of the system.
