It is in /usr/lib/python2.6/site-packages/ipalib/plugins on all of my clusters. I will include ipa-python in ambari-metrics-assembly/pom.xml.

Hi Sid, I tried to test it on HDP2.5.0.0/trunk. but I was not able to bring the metrics up. Do you have this experience? But I will try to test it on HDP2.4/trunk. - Qin ----------------------------------------------------------- This is an automatically generated e-mail.
