Victor Li commented on HBASE-15242:
-----------------------------------
[~dmanning] Make sense to me. After examining the client code, I found that the
client will report to callers with exception like `CallTimeoutException` for
timed out calls, `RemoteWithExtrasException` for exceptions from server, or
some others defined in the subdirectory
`hbase-client/src/main/java/org/apache/hadoop/hbase/ipc`. I think we can make
three counter metrics for timeout calls, server side exceptions and the rest of
other exceptions.
It's a bit tricky for the case of retry exhausted, there are two exceptions,
`RetriesExhaustedException` and `RetriesExhaustedWithDetailsException`, I guess
one is from client side and another one is from server side. I don't know if
they are already a part of the call timeout and remote exception.
