Supervise metrics per queue in Ambari

[#1]

Dear experts,

I want to show some metrics in Ambari that doesn't seem available out of the box in widget list. This is for supervision needs. Do you know how can I show:

• Used CPU, RAM, containers, etc per Queue
• Number of file descriptors per data node

Also, is there a list of all available metrics in Ambari?

@Luis Size Please see

https://cwiki.apache.org/confluence/display/AMBARI/Enhanced+Service+Dashboard to see how to create custom Ambari widgets. Also there are widgets available for HDFS/Yarn/HBase in Widget browser.

Key is

If the existing service in Ambari is pushing the metrics to Ambari metrics collector then minimal work needs to be done.

• What's the metrics for "number of file descriptors

Can you help me on these specific questions ?

Thanks
