Comment 26 Asaf Hirshberg 2016-12-07 05:57:48 UTC 
Pratik,

Are the nodedown alerts are shown after deployment finished or after some time(or operations/workload)?
Comment 29 Asaf Hirshberg 2016-12-08 06:45:20 UTC 
Verified using openstack-tripleo-heat-templates-liberty-2.0.0-41.el7ost.noarch

Tested the status of rabbitmq using following scenarios:
-after deployment finished.
-after cluster operations
-after/during opnestack operations using Rally( create and delete instances x20times)
Results=all passed
