> Surface hbase metrics from perconnection to global metrics
> Currently in phoenix client side, HBASE metrics are recorded and surfaced at
> Per Connection level. PHOENIX-4370 allow it to be aggregated at global level,
> i.e., aggregate across all connections within in one JVM so that user can
> evaluate it as a stable metrics periodically.
> COUNT_RPC_CALLS("rp", "Number of RPC calls"),
> COUNT_REMOTE_RPC_CALLS("rr", "Number of remote RPC calls"),
> COUNT_MILLS_BETWEEN_NEXTS("n", "Sum of milliseconds between sequential
> next calls"),
> COUNT_NOT_SERVING_REGION_EXCEPTION("nsr", "Number of
> NotServingRegionException caught"),
> COUNT_BYTES_REGION_SERVER_RESULTS("rs", "Number of bytes in Result
> objects from region servers"),
> COUNT_BYTES_IN_REMOTE_RESULTS("rrs", "Number of bytes in Result objects
> from remote region servers"),
> COUNT_SCANNED_REGIONS("rg", "Number of regions scanned"),
> COUNT_RPC_RETRIES("rpr", "Number of RPC retries"),
> COUNT_REMOTE_RPC_RETRIES("rrr", "Number of remote RPC retries"),
