How to monitor JVM in Ambari

rudrapbiswas — Mon, 12 Dec 2016 21:30:16 GMT

How can I add a wizard to visually monitor the JVM for my cluster in Ambari?

As an alternate I was unable to install the jVisualVM in admin node running centos6.

JVM is measured in these 3 Ambari service metrics:

NameNode Heap (HDFS): The percentage of NameNode JVM Heap used.
ResourceManager Heap (YARN): The percentage of ResourceManager JVM Heap used.
HBase Master Heap (HBase): The percentage of NameNode JVM Heap used.

You can add these native widgets to the Ambari dashboard if you do not see them. See section 2.1.2 in: http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_Ambari_Users_Guide/bk_Ambari_Users_Guide-20160509.pdf

Alternatively, you can leverage Ambari 2.2 new grafana dashboarding capabilities to create much more granular and customized dashboard and reporting components from Ambari service metrics:

@rudra,

Adding to Greg's answer, Ambari Metrics Service tracks the JVM state of every component through metrics. These can be visualized in Grafana from Ambari-2.2.2.

If you are interested in Ambari Server's JVM state itself, that is still WIP and is available in trunk. Tracked through https://issues.apache.org/jira/browse/AMBARI-17589.

- As Aravindan mentioned that there is an Epic JIRA for Capturing & visualizing the metrics for Ambari Server: https://issues.apache.org/jira/browse/AMBARI-17589

- However if you want to monitor the Current JVM statistics/metrics (not historical data) then you can use the jconsole or jvisualvm kind of utilities as described in:
