Supervise metrics per queue in Ambari

luis_size1 — Mon, 14 Mar 2016 19:58:19 GMT

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?

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