> Currently FairScheduler's FSOpDurations records some scheduler operation metrics: nodeUpdateCall, preemptCall, etc. We may need similar for CapacityScheduler. Also, need to add more metrics there. This could help monitor the RM scheduler performance, and get more insights whether scheduler is under-pressure.
