Summary

Average number of processes in a host system that are ready for execution but must wait to be processed by the CPU

Configuration

The actual threshold value largely depnends on the system architecture. The best practice indicates that 5 minute Load Average above 7 is problematic. However in some applications, you might consider even the lower value as the threshold to generate the alert.

Causes

There are many reasons for the CPU Load to spike. Please use standard SAP Tools like SM50 etc to find the root cause of the problem

Resolutions

The resolution will depend on the cause, some of the actions may include changing the load-balancing parameters of the Message Server, switching Operation Mode or provisioning additional application server
