      The current timeseries implementation allows us to infer how often WT I/O requests result in a WT cache hit vs not.

      I define a logical I/O as a single request for a block or page (whatever our most granular request is) whether from cache or disk.

      Is there explicit tooling that would let us

      • aggregate the actual number of logical I/Os for a given query shape
      • aggregate the actual number of logical I/Os for all query shapes

      and then for the above

      • aggregate the number of times the logical I/O was serviced by a WT cache hit
      • aggregate the number of times the logical I/O was serviced by a filesystem cache hit
      • aggregate the number of times the logical I/O resulted in a physical I/O request
