>                 Key: HBASE-8868
>                 URL: https://issues.apache.org/jira/browse/HBASE-8868
>             Project: HBase
>          Issue Type: Improvement
>          Components: metrics, regionserver
>    Affects Versions: 0.94.8, 0.95.1
>            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.
