Subject [jira] [Created] (AURORA-118) Add percentiles to @Timed, or write a new decorator to add percentiles

----------------------------------

             Summary: Add percentiles to @Timed, or write a new decorator to add percentiles
                 Key: AURORA-118
                 URL: https://issues.apache.org/jira/browse/AURORA-118
             Project: Aurora
          Issue Type: Task
          Components: Scheduler
            Reporter: Bill Farner


The @Timed annotation is really nice for 'sprinkling on' instrumentation, but doesn't expose
percentiles.  We've seen several areas where a long tail of slow operations caused major performance
issues, so spotting these with percentiles would be very helpful.
