Monitor virtual processors with the onstat-g rea command

Use the onstat-g rea command to monitor the number of threads in the ready queue.

onstat-g rea displays this information:

  • The status field in the output shows the value ready when the thread is in the ready queue.
  • The vp-class output field shows the virtual processor class on which the thread executes.

If the number of threads in the ready queue is growing for a class of virtual processors (for example, the CPU class), you might have to add more of those virtual processors to your configuration.
