[Alarm]QueryCPUUsage

  • Last UpdatedJul 19, 2023

Defines the percentage of processor use you want to allocate to query searches.

If programs and other processes are experiencing 'freezing' during historic searches, you should reduce the CPU Usage value.

If your searches are slow and are taking longer than expected to return results, you may achieve better results by increasing the CPU Usage value.

However, we recommend that you try to reduce the number of records involved in the search before you increase the CPU usage settings. Increasing the CPU Usage above 90% may have a detrimental effect on drivers and client connections, so we recommend that you should not increase CPU Usage above 90% unless specifically instructed to do so by Technical Support.

Note: This parameter can also be applied to a specific cluster or alarm server process. For more information, see Configure Alarm Parameters for a Specific Cluster or Process.

Allowable Values:

0 to 100

Default Value:

80
