CPU Usage Monitoring

In order to add a CPU usage counter, press the 'Add' button located on the main toolbar, selected the 'CPU Usage' counters category in the left-side view and then select an appropriate CPU usage counter in the middle view. By default, SysGauge will monitor all CPUs, but if required, the user can select a specific CPU to monitor in the right-side view. In addition, in order to monitor the CPU usage in a remote computer via the network, press the 'Connect' button located in the bottom-left corner and specify the host name of the remote computer to monitor.

SysGauge CPU Usage Monitoring
  • CPU Usage - this counter is the primary indicator of the processor activity and it displays the average percentage of the processor busy time observed during the sample interval.
  • CPU Usage User - this counter measures the percentage of elapsed time the processor spends in the user mode. User mode is a restricted processing mode designed for user applications, environment subsystems, and integral subsystems.
  • CPU Usage System - this counter measures the percentage of elapsed time that the processor spent executing code in privileged mode. When a Windows system service in called, the service will often run in privileged mode to gain access to system-private data.
  • CPU Interrupt Time - this counter measures 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. This counter displays the average busy time as a percentage of the sample time.
  • CPU Interrupt Rate - this counter measures the average rate, in incidents per second, at which the processor received and serviced hardware interrupts. 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. The system clock typically interrupts the processor every 10 milliseconds, creating a background of interrupt activity. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
