Processor - % Processor Time The % Processor Time counter describes the percent of time a particular processor is busy. System - % Total Processor Time The % Total Processor Time counter describes the percent of time all processors are busy. In a multiprocessor computer, this counter is equal to the sum of % Processor Time for each processor divided by the number of processors. If the server workload is shared equally among all processors, System: % Total Processor Time is a good measure of processor activity. System - Process Queue Length Processor Queue Length is the instantaneous length of the processor queue in units of threads. All processors use a single queue in which threads wait for processor cycles. This length does not include the threads that are currently executing. This is an instantaneous count, not an average over the time interval. Hewlett-Packard Company 18
