      Description

      Patch adds the following metrics;

      • time spent anticompacting data before participating in a consistent repair
      • time spent creating merkle trees
      • time spent syncing data in a repair
      • approximate number of bytes read while creating merkle trees
      • number of partitions read creating merkle trees
      • number of bytes read while doing anticompaction
      • number of bytes where the whole sstable was contained in a repairing range so that we only mutated the repair status
      • ratio of how much we anticompact vs how much we could mutate the repair status
      • total time spent as a repair coordinator
      • total time spent preparing for repair
