> 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: 0.94.8, 0.95.1
> Reporter: Viral Bajaria
> Assignee: Wei-Chiu Chuang
> Priority: Minor
> Fix For: 3.0.0, 2.3.0
>
> Attachments: HBASE-8868.master.001.patch
>
>
> 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.
