Description

Is your feature request related to a problem? Please describe.
We don't report the completion of workflows during replays. This is a good default behavior for these main completion counters, but we are lacking any reporting of replays counters.

Describe the solution you'd like
Replay metrics could be important for detecting the anomaly behavior of the system. We should discuss how do we want to report replays metric.

  • Do we want to report them by status codes?
  • Do we want to just report a total number of replays?
  • Only full replays or partial too?
