Description

The cpuusage event trigger is invoked when the system's CPU usage exceeds the ActionThreshold value of the system's CPUUsageMonitoring attribute for a duration longer than the ActionTimeLimit value. The trigger is not invoked if it was invoked on the system within the last five minutes. 

See When a resource comes online. 

This event trigger is configurable. 

Usage

- cpuusage  triggertype system  cpu_usage 

• triggertype—represents whether trigger is custom (triggertype=0) or internal (triggertype=1).

  If 0, the trigger is invoked from:

  If 1, the system reboots by invoking the trigger from:

  /opt/VRTSvcs/bin/internal_triggers/cpuusage

• system—represents the name of the system.
• cpu_usage—represents the percentage of CPU utilization on the system.

Set following values in the system's CPUUsageMonitoring attribute: 

• Enabled = 1
• ActionTimeLimit = Non-zero value representing time in seconds.
• ActionThreshold = Non-zero value representing CPU percentage utilization.
• Action = CUSTOM or REBOOT.

  CUSTOM—Invokes trigger from:

  REBOOT—invokes trigger from:

  and the system reboots.
