Elliott Clark commented on HBASE-15163:
---------------------------------------
bq.Yes but they are not histogram, so still have the 'instantaneous rate is
controlled by how long inbetween metrics snapshots' issue, right?
No they are continuous counting metrics. If the metrics snapshots once when
there's a spike and another time when there's not then the spike isn't lost,
just averaged out.
For rate that's computed once per snapshot that information is lost.
> Add sampling code and metrics for get/scan/multi/mutate count separately
