currently in ambari 2.1.2
i can see metrics for ALL region servers when i create a widget.
can i create metrics per region server.
objective: Find out whether hot spotting is occurring or not.
Currently i am at a loss,because all metrics for hbase rs are AGGREGATED
this is helpful. i got grafana up but i notice the dashboard metric queries are again based on
aggregated values when i select region server as a component. screen-shot-2015-12-30-at-101503-am.png
agree we don't need ui per se for this. Hot spotting was just 1 use case.
At an aggregated level, its useful to see if something is abnormal. next step is to find out which region server/ host has abnormal behaviour.
