Josh Elser updated HBASE-20233:
-------------------------------
Environment: (was: 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)
