Description

Problem

These are number widgets on Grafana and is expected to show point in time information for "Average Regions per RegionServer" 
ambari-web that shows expected correct information gets the data from "Hadoop:service=HBase,name=Master,sub=Server.averageLoad" jmx metric via ambari-server metrics API resource.

It seems having aggregator as "avg" looks to be causing this issue. when there are more than one HBase master than the metric value is averaged across all masters
