This counter measures the percentage of time the processor is accomplishing meaningful work (i.e., nonidle threads). Valid values range from 0 to 100 (%). This counter can mask a processor bottleneck on a multiprocessor system. To determine a processor bottleneck, examine the Processor: % Processor Time for the questioned server/node. • Avg Processor Queue Length The average number of threads waiting for processor time in the cluster. This counter can mask a processor bottleneck on a multiprocessor system. To determine a processor bottleneck, examine the System: Processor Queue Length for the questioned server/node. • Avg % Committed Bytes in Use The average percent of currently committed memory (Bytes) of the Commit Limit in the cluster. The committed memory is the physical memory currently in use, where the same amount is reserved in the paging file should it need to be paged out. The Commit Limit is an upper limit of the virtual memory (i.e., total RAM + paging file) that can be allocated on a system.
