Processors
The following information is provided for processors.
Processors Status
•Average Processor Utilization %—The average percentage of time that all the processors on the system are busy executing non-idle threads. On a multiprocessor system, if all processors are always busy, the metric reads 100%; if all processors are 50% busy, the metric reads 50%; if one-fourth of the processors are busy, the metric reads 25%. Average Processor Busy % can be viewed as the fraction of the time spent doing useful work.
Each processor is assigned an idle thread in the idle process consuming unproductive processor cycles not used by another thread. Some processors might be more heavily loaded than other processors. In this case, the total processor time percentage is the average of the loads on each processor.
•Busiest Processor Utilization %—The average utilization of the logical processor with the highest utilization. This value is equal to the Average Processor Utilization % if the server is using one processor core.
•Processor Busy %—The percentage of time that the processor is executing a non-idle thread.
•Context Switches/Sec—The number of thread context switches at which all processors on the server are switched from one thread to another each second. Context switches occur when a running thread voluntarily relinquishes the processor, is preempted by a higher-priority ready thread, or switches between user mode and privileged (kernel) mode to use a subsystem service.
•Interrupts/Sec—The average number of hardware interrupts the processor is receiving and servicing each second.
Average Processor Utilization % and Highest Processor Utilization % are used to determine processor performance.
Processors Inventory
•Processor Support—Lists the number of processors supported by the server
•Processors—Displays the number of processors installed on the server and a summary of the processors (type, speed, and cache size)
