MONITORING FOR PROCESSOR BOTTLENECKS

MAJOR PROCESSOR RELATED COUNTERS TO WATCH:
Processor: %Processor Time - How busy the microprocessor is. Processor is a bottleneck if sustained >80%
Processor: Interrupts/sec - Rate of service requests from peripheral devices. If you have a high rate of interrupts/sec with no corresponding hardware functions then you may have a bad piece of hardware. Should be between 100 and 1000. Spikes to 2000 are ok.
System: Processor queue length - Number of threads waiting to be serviced. >2 then processor is a bottleneck. Queue length will always be zero unless you are also monitoring a thread specific counter (Context switches/sec is number of threads switched/sec by the processor and is good to use).
