Description

Invoked when a system becomes overloaded because the load of the system's online groups exceeds the system's LoadWarningLevel attribute for an interval exceeding the LoadTimeThreshold attribute.  

For example, say the Capacity is 150, the LoadWarningLevel is 80, and the LoadTimeThreshold is 300. Also, the sum of the Load attribute for all online groups on the system is 135. Because the LoadWarningLevel is 80, safe load is 0.80*150=120. Actual system load is 135. If system load stays above 120 for more than 300 seconds, the LoadWarningLevel trigger is invoked. 

Use this trigger to notify the administrator of the critical event. The administrator can then switch some service groups to another system, ensuring that no one system is overloaded.  

This event trigger is non-configurable. 

Usage

- loadwarning  triggertype  system available_capacity 

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

  For this trigger, triggertype=0.

• system—represents the name of the system.
• available_capacity—represents the system's AvailableCapacity attribute. (AvailableCapacity=Capacity-sum of Load for system's online groups.)
