      Fast truncate has no Grafana representation, so a truncate problem on a live node has to be diagnosed from raw statistics.

      Add panels covering:

      • truncate rate, split by leader and follower
      • truncate list length and its high water mark
      • search cost: calls, entries walked, and the resulting entries walked per call
      • GC activity: runs and entries removed
      • truncate write conflict rate

      Depends on the statistics added under the truncate list statistics ticket.
