Description

Ambari Metrics Grafana is reporting 94.9 Avg Num Regions per RegionServer compared to HBase UI RegionServers sections which is showing 186 - 192 regions for all 8 regionservers.

Time picker is set to last hour and HMaster UI is refreshed so it's not a misaligned reporting time issue.

Ambari's Grafana shows 1519 regions for 8 regionservers but Avg Num Regions as 94.9 rather than what you would expect 1519 / 8 should equal 189.875.
