CPU Usage Summary

Overview

The CPU Usage Summary report shows the summary of CPU usage over the last hour on a minute-by-minute basis. It is displayed as a table and a line graph.

Fields

Field name Explanation

% Total Interrupt Time Processor usage (%) for processing hardware (devices that cause an interrupt, such as system clock, mouse, disk driver, data communication line, NIC, and other peripheral devices) interrupts. The maximum value that is displayed is 100, even in a multi-processor environment.

Context Switches/sec Number of context switches (when the executing thread arbitrarily releases the processor and is interrupted by a thread with higher priority, the mode is switched between the user mode and the privileged mode to use either the executive or subsystem service) in the processor that were caused by all process threads (switches/second).

CPU % Processor usage (%). Percentage of time the processor spent executing non-idle threads. The maximum value that is displayed is 100, even in a multi-processor environment.

Privileged CPU % Processor usage in the privileged mode (%). Percentage of time the processor spent executing non-idle threads in the privileged mode. The maximum value that is displayed is 100, even in a multi-processor environment.
This field is a configuration element of the CPU % field.

Processor Queue Length Number of threads in the processor queue that are ready to be executed. Normally, if the queue length continues to exceed 2, it indicates processor congestion.^#1

System Calls/sec Number of times the processes being executed by the processor invoked a system service routine (calls/second).

Total Interrupts/sec Number of hardware (devices that cause an interrupt, such as system clock, mouse, disk driver, data communication line, NIC, and other peripheral devices) interrupts that the processor received and processed (interrupts/second).
DPC (delay procedure call) interrupts are not included. Normally, if the value in this field has increased significantly when there is no system activity, it indicates a hardware problem, such as presence of a slow device.

User CPU % Processor usage in the user mode (%). Percentage of time the processor spent executing non-idle threads in the user mode. The maximum value that is displayed is 100, even in a multi-processor environment.
This field is a configuration element of the CPU % field.
