> Noticed this poking at metrics. The MBean "Hadoop:service=HBase,name=RegionServer,sub=Regions" carries per region metrics. They are all formatted like so:
> {code}
> Namespace_default_table_IntegrationTestBigLinkedList_metric_incrementTime_98th_percentile: 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_incrementTime_99th_percentile: 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_incrementTime_99.9th_percentile: 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_appendTime_num_ops: 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_appendTime_min: 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_appendTime_max: 0,
> Namespace_default_table_IntegrationTestBigLinkedList_metric_appendTime_mean: 0,
> {code}
> In the middle of them all is a metric named...
> {code}
> numRegions: 15,
> {code}
> It has a different format and it is out of scope when compared to the other metrics in this mbean; it belongs better elsewhere, perhaps in the Server bean.
> I noticed it because it breaks the parse done by tcollector scraping our metrics from /jmx
> It was added long ago in HBASE-14166
