Spurious numbers in metrics #430

Open
@mgrabovsky

Description

In the 48 hours following the deployment of the Prometheus metrics endpoint, at least two bugs have been made apparent thanks to the Grafana dashboard:

  1. Failed tasks often (but not always) seem to be counted twice in retrace_tasks_finished{result="fail"}.
  2. The number of running tasks (retrace_tasks_running) sporadically jumps up to wild numbers, such as 70, 18 or 39, for a few minutes at a time. The maximum allowed number of running tasks (MaxParallelTasks) is 12 on retrace.fp.org, so these numbers make no sense.
