This rule collects performance data for the Processor Total Percent Interrupt Time performance counter. This information is collected and is exposed one or more Views and/or Reports.
The Processor Total Percent Interrupt Time performance counter exposes the time the processor spends receiving and servicing hardware interrupts during sample intervals. This value is an indirect indicator of the activity of devices that generate interrupts, such as the system clock, the mouse, disk drivers, data communication lines, network interface cards and other peripheral devices. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended during interrupts. Most system clocks interrupt the processor every 10 milliseconds, creating a background of interrupt activity suspends normal thread execution during interrupts. This counter displays the average busy time as a percentage of the sample time.
