             Summary: Export a stat to track status update handling delay
                 Key: AURORA-549
                 URL: https://issues.apache.org/jira/browse/AURORA-549
             Project: Aurora
          Issue Type: Task
          Components: Scheduler
            Reporter: Bill Farner
            Priority: Minor


{{TaskStatus}} has a timestamp field that would be useful for us to track our delay in handling the status updates.  The timestamp is set by the executor or slave, so it does not help with measuring processing delay in the scheduler, and is not guaranteed to be monotonically-increasing.  We could, however, use this to track a windowed average of status update delay to know the slave->scheduler complete delay.
