Monitoring CPU load

A continuous high level of CPU usage can be an indicator that it might be necessary to scale up/out the system.

For the CPU load the same arguments as for the heap usage regarding peaks are true. So if a high CPU load is detected (> 60% for more than one hour), first it should be analyzed, if short peaks or exceptional use cases are the reason. If this is the case no direct reaction is needed.

If the defined limit for CPU usage is exceeded, there are two possible measures:
