Monitors the distribution of load on the CPUs in the system. For each CPU in the system, this VI returns the total load as a percentage of capacity. This VI also returns the percentage of CPU time devoted to each priority level, the percentage of idle CPU time, and the percentage of CPU time devoted to Timed Structures and interrupt service routines (ISRs).

Inputs/Outputs

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • i1dnclst.png CPU loads —

    CPU loads returns data corresponding to the distribution of load for each CPU in the system. The Nth element of this array corresponds to the Nth CPU in the system.

    CPU numbering begins at zero.

  • idbl.png Total Load (%) —

    Total (%)—Returns the total CPU usage as a percentage of capacity.

  • idbl.png ISR Load (%) —

    Time Critical (%)—Returns the CPU usage devoted to time-critical threads as a percentage of total CPU capacity.

  • idbl.png Timed Structure Load (%) —

    Timed Structures (%)—Returns the CPU usage devoted to timed structures as a percentage of total CPU capacity.

  • idbl.png Other Thread Load (%) —

    High (%)—Returns the CPU usage devoted to high priority threads as a percentage of total CPU capacity. (Real-Time Linux) CPU usage data is unavailable for this priority level. This output returns a value of 0.

  • idbl.png Total Load (%) —

    Above Normal (%)—Returns the CPU usage devoted to above normal priority threads as a percentage of total CPU capacity. (Real-Time Linux) CPU usage data is unavailable for this priority level. This output returns a value of 0.

  • idbl.png Total Load (%) —

    Normal (%)—Returns the CPU usage devoted to normal priority threads as a percentage of total CPU capacity.

  • idbl.png Total Load (%) —

    Background (%)—Returns the CPU usage devoted to background priority threads as a percentage of total CPU capacity. (Real-Time Linux) CPU usage data is unavailable for this priority level. This output returns a value of 0.

  • idbl.png Total Load (%) —

    Idle (%)—Returns the amount of idle CPU time as a percentage of total CPU capacity.

  • idbl.png Total Load (%) —

    ISR (%)—Returns the CPU usage devoted to interrupt service routines (ISRs) as a percentage of total CPU capacity.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
