CPU Used Status (real-time report indicating the CPU usage status)

Active CPUs

Number of processors

CPU %

Processor usage rate (%). This is also the average value for all processors.

Idle %

Percentage of the time the processor was in idle status (%). This is also the average value for all processors.

Interrupt Counts/sec

In Windows:

Frequency of hardware interrupt reception processing performed by the processor (times/second); hardware refers to devices that generate interrupts, such as system clock, mouse, disk driver, data communication line, NIC, and other peripheral devices. This value does not include DPC (delayed procedure call) interrupts. Normally, if the value of this field increases greatly while there is no system activity, a hardware problem is suspected (such as a slow device).

In UNIX:

Frequency of interrupts (times/second)

Polling Time

Time the performance data was collected on the PFM - RM host

Processor Queue Length

Number of requests ready for execution that are waiting in the processor queue for processor time. Normally, if the queue length exceeds 2 continuously, the processor is busy.

Run Queue Avg 5 min

Average number of threads waiting in the execution queue for the past 5 minutes.

In the case of UNIX (HP-UX, Solaris, and AIX), this value does not include the number of threads waiting for I/O. In Linux, this value does contain the number of threads waiting for I/O.

System %

Usage rate for a processor that was executed in the kernel mode (%). This is also the average value for all processors.

Target Host Time

Time the performance data was collected on the monitored host

User %

Usage rate for a processor that was executed in the user mode (%). This is also the average value for all processors.

Wait %

Percentage of the time the processor was in I/O wait status (%). This is also the average value for all processors.

CPU Per Processor Status

Displays the current processor usage rate for each processor.
