Gregory Chanan commented on HBASE-6591:
---------------------------------------
We had a customer with a very slow-running application that consisted mainly of
checkAndPuts. checkAndPut latency looked good. It would have been nice to
just look at the metrics and be able to eliminate the possibility that their
checkAndPuts simply weren't getting executed.

> So clients can figure out this metric for themselves, but it would be useful

> clients.
