    Description

      We had a lot of difficulty trouble-shooting some recent issues on bolt80. We need the following metrics added:

      • number of ops in the PREPARE queue
      • number of ops in the APPLY queue
      • number of milliseconds of spinlock contention (histogram?)
      • consensus error rate seen by leader
      • consensus RTT seen by leader
