(Optional) Enabling Individual Region, Table, and User Metrics for HBase
Other than HBase RegionServer metrics, Ambari disables per region, per table, and per user metrics by default, because these metrics can be numerous and therefore cause performance issues.
If you want Ambari to collect these metrics, you can re-enable them; however, you should first test this option and confirm that your AMS performance is acceptable.
On the Ambari Server, browse to the following location:
/var/lib/ambari-server/resources/common-services/HBASE/0.96.0.2.0/package/templatesEdit the following template files:
hadoop-metrics2-hbase.properties-GANGLIA-MASTER.j2hadoop-metrics2-hbase.properties-GANGLIA-RS.j2Either comment out or remove the following lines:
*.source.filter.class=org.apache.hadoop.metrics2.filter.RegexFilterhbase.*.source.filter.exclude=.*(Regions|Users|Tables).*Save the template files and restart Ambari Server for the changes to take effect.

If you upgrade Ambari to a newer version, you must re-apply this change to the template file. |
