Problem to be solved

We have a tracker component which consumes events from other components in core workflow. Tracker needs to analyse and instrument the events to find out which peers are participating in the cluster. This will help our operators to determine cluster health and notify other peers if they are not participating.

Proposed solution

Tracker will analyse the events to calculate which peers participated by:

  • If we receive parSigDBInternal event then we participated.
  • If we receive an parSigEx event with a given shareIdx, then that peer participated.
  • Return all participated peers by shareIdx (including ourselves).

Tracker will report the result as:

  • Only log (INFO level) which peers didn't participated and do not repeat identical logs if same set of participants didn't participate in next duty report to avoid spamming.
  • Set a prometheus gauge vector per peer: participationGauge.WithLabelValues(duty.Type.String(), peerName).Set(participatedBool)
