Supervise metrics per queue in Ambari

avatar
Contributor

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?
