The mdiag -S command is used to present information about the status of the scheduler.

This command will report on the following aspects of scheduling:

• General Scheduler Configuration

  • Reports detected overflows of node, job, reservation, partition, and other scheduler object tables
• High Availability
  • Configuration
  • Reports health of HA primary
  • Reports health of HA backup
• Scheduling Status
  • Reports if scheduling is paused
  • Reports if scheduling is stopped
• System Reservation Status
  • Reports if global system reservation is active
• Message Profiling/Statistics Status
• Moab scheduling activities (only with mdiag -S -v -v)
  • Activity[JobStart]: Time Moab spends telling the RM to start a job and waiting for a response.
  • Activity[RMResourceLoad]: Time Moab spends querying license managers and nodes.
  • Activity[RMWorkloadLoad]: Time Moab spends querying resource managers about jobs (as opposed to nodes)
  • Activity[Schedule]: Time Moab spends prioritizing jobs and scheduling them onto nodes.
