Dell SmartFabric OS10 User Guide Release 10.5.3

Monitor CPU Utilization

You can set CPU thresholds so that alarms are triggered when CPU utilization reaches the high or low threshold level. CPU utilization is monitored as a running average percentage over predefined intervals of five seconds, one minute, and five minutes. By default, this feature is enabled with a higher threshold value so that alarms do not generate frequently.

When CPU utilization crosses the high threshold, a critical alarm triggers. A warning alarm triggers when CPU utilization crosses the low threshold. The alarms clear when CPU utilization goes below the corresponding threshold. To view the current active alarms in the system, use the show alarms command.

The util-threshold cpu command allows you to configure the high and low threshold values. Before configuring the threshold values, configure a syslog server to collect and store the syslog messages. To view the configured CPU utilization thresholds, use the show util-threshold cpu command.
