Abhishek Singh Chouhan commented on HBASE-18374:
------------------------------------------------
[~apurtell] [~lhofhansl] Let me know if this looks good or not. Was not sure if
we want to add slowReq counters for these new metrics so for now have not added
those, can add those too if people want (or later if there's demand for these
later).

> At the RS level we have latency metrics for mutate/puts and deletes that are
> updated per batch (ie. at the end of entire batchop if it contains put/delete
> update the respective metric) in contrast with append/increment/get metrics
> that are updated per op. This is a bit ambiguous since the delete and put
> metrics are updated for multi row mutations that happen to contain a
> put/delete. We should rename the metric(eg. delete_batch)/add better
> description. Also we should add metrics for single delete client operations
> that come through RSRpcServer.mutate path. We should also add metrics for
> checkAndPut and checkAndDelete.
