Subject Re: ambari just for monitoring?

You could look at the resource providers in the 
org.apache.ambari.server.controller.gsinstaller package.  They basically 
read the cluster definition from an artifact of the gsInstaller 
(gsInstaller-hosts.txt).  The default metrics providers are still used 
for monitoring through Ganglia and JMX.
