Hi rahul. The collector and server are on the same host and so is ambari grafana As I mentioned, removal of a widget made everything else appear. I have added a graph in grafana for the metric widget I removed

hi Neeraj, The Hbase ms and rs are up. i am able to see the summary. but not the graphs. I seemed to have worked around the problem by deleting a widget. (read latency widget) and everything appeared. even though 1 latency widget is not there. i added a graph via ambari-grafana for read latency and the metric is now available there

When i login to the ui, metrics summary for hbase is not shown. for the rest like hdfs/storm the metrics show up. collector and ambari server are on the same host. The exception i get in server log is: -------------------------------- DEBUG [qtp-ambari-client-26 - /api/v1/clusters/cluster_name/services/HBASE/components/HBASE_REGIONSERVER?_=1454039202858] MetricsRequestHelper:116 - Error getting timeline metrics : Read timed out java.net.SocketTimeoutException: Read timed out at java.net.SocketInputStream.socketRead0(Native Method) -------------------------------- any help would be appreciated.

hi i faced the same issue while starting up nimbus (ambari 2.2.0.0 , hdp 2.3.2.0). To resolve: i installed hdfs client on the host and nimbus was able to start up as it found "/usr/hdp/current/hadoop-client/conf"

i am able to see per host metrics now in ambari-grafana git commit 5 hours ago 🙂 https://github.com/u39kun/ambari-grafana/commit/f6048e17a901183b5451b66e75d71184c1999fa5

Hi Artem, 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.

hi Rahul 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 is there a way to see per host/region server the metric ?

i tried steps here http://docs.hortonworks.com/HDPDocuments/Ambari-2.1.1.0/bk_ambari_reference_guide/content/_enabling_hbase_region_and_table_metrics.html but no effect
