> Key: HBASE-18982
> URL: https://issues.apache.org/jira/browse/HBASE-18982
> Project: HBase
> Issue Type: Bug
> Components: Coprocessors, metrics
> Reporter: Ashish Misra
> Priority: Minor
>
> The Metrics-Region-Source class maintains metrics for a given region.
> The Metrics-Region-Aggregate-Source class allows register/deregister of
> objects of type Metric-Region-Source. The get-Metrics method on
> Metrics-Region-Source-Aggregate class, gets metrics from all the
> Metrics-Region-Source objects registered with it.
> The Metrics-Region-Source object is deregistered when the region is closed.
> When a Metrics-Region-Source object is deregistered, its directly removed
> from the set maintained by Metrics-Region-Aggregate-Source object. In such a
> case, the final metrics of Metrics-Region-Source object are lost. These
> metrics must be logged one last time before the Metrics-Region-Source object
> is removed.
