Investigate new statistics from the block manager

    • Type: Icon: Task Task
    • Resolution: Done
    • Priority: Icon: Major - P3 Major - P3
    • None
    • Affects Version/s: None
    • Component/s: None
    • StorEng - Refinement Pipeline

      Summary
      This ticket contains three different work items:

      • The header Block manager statistics appears three times in our stat_data.py file. I think at least one should be renamed to Block cache statistics.
      • Investigate if we can create new statistics for the latency when it comes to reads/writes to the disk.
      • Investigate if we can generate traces when the IOPS are getting slow. We need to define what "slow" is, see WT-9929 for this task.

      Motivation

      • Does this affect any team outside of WT?
        It would be great for the support team to have better stats around I/O issues. 
      • Is this issue urgent?
        The earlier the better.

      Acceptance Criteria (Definition of Done)

      • Testing
        If new stats are created, make sure they are generated.
      • Documentation update
        Probably none
