This is openstack newton, with installed packages shown below, /openstack/venvs/ceilometer-14.0.5/lib/python2.7/site-packages/ cotyledon-1.6.6

I don't see the same problem in other server with openstack newton, but ceilometer 14.0.7 and cotyledon-1.6.7. I have seen for the "ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile" error in both the versions of cotyledon-1.6.6 and 1.6.7 inside the file below, /openstack/venvs/ceilometer-14.0.X/lib/python2.7/site-packages/amqp/connection.py

and found they are configured correctly, so someone please help me with this bug

Thanks in Advance!! Please find the log below from ceilometer-agent-notification.log
