Yu Li commented on HBASE-18374:
-------------------------------
I could see some incompatible changes on metrics names (such as
regionserver.server.mutate -> regionserver.server.put), which will cause
existing monitoring on those metrics not working anymore after upgrading.
The metrics compatibility is included in "Operational Compatibility" in our
[ref guid|http://hbase.apache.org/book.html#hbase.versioning] and we're allowed
to break it in major/minor versions but not in patch versions. So I think it's
ok to go into branch-1/branch-2/master but please fill in the release notes.
Thanks.

> 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.
