[jira] [Created] (HBASE-8868) add metric to report client shortcircuit reads

Viral Bajaria created HBASE-8868:
------------------------------------

             Summary: add metric to report client shortcircuit reads
                 Key: HBASE-8868
                 URL: https://issues.apache.org/jira/browse/HBASE-8868
             Project: HBase
          Issue Type: Improvement
          Components: metrics, regionserver
    Affects Versions: 0.95.1, 0.94.8
            Reporter: Viral Bajaria
            Priority: Minor


With the availability of shortcircuit reads, when the feature is enabled there is no metric which exposes how many times the regionserver was able to shortcircuit the read and not make a IPC to the datanode.

It will be great to add the metric and expose it via Ganglia.
