Thanks Jeff. This is I believe modifying the source code and deploying to run this behavior. I am more interested to add and configure any new service like Storm so that I can monitor storm running on different hosts.
I have also created a JIRA story (AMBARI-2813) and linked to parent story (AMBARI-2714).
I am seeing that there is no provision even to configure or customize the existing services like Ganglia through Ambari UI. I have used HDP1.3 release docs to install and configure HDP1.3 on my local centOS machine which is 1 node cluster and running all services fine.
