Processor Utilization is the percentage of time that the core/processor is actually occupied compared against the total time the core/processor is available for use. For example if the CPU is occupied for 45 seconds during a minute, its utilization for this period is 75%.
To derive this figure the processors are polled every five seconds and where the average for any processor exceeds 70% (the default threshold) over the Agent cycle (5 or 15 minutes) an Alert is generated.
The Dashboard will display the average and maximum utilization for each processor over the Agent cycle. Where a processor fails this will be displayed in the clickable information line, for example CPU2.
