      Description

      As discussed here,

      it would be useful to add "utilization" (aka "duty cycle") as a metric, which is the sum of all the timings divided by the window length. That can tell you how much idle time there is in the event loop (how much headroom before the job will start falling behind).

      It is useful to add this metric for the event loop.
