Hi, Rohit: Thanks for the reply.
We have CS instances connecting to either a single RabbitMQ broker, or a cluster of 2/3 brokers thru a load balancer VIP. The results are always the same . And yes, the messages are published to brokers.

I just noticed that for CS 4.3.2, there are two TCP connections from cloudstack-management java process to RabbitMQ cluster, but for CS 4.5.1 there is only one TCP connection to RabbitMQ cluster. Can someone please confirm that this is correct? If this is the expected behavior, I need to update our Nagios setup accordingly. Is your mgmt server publishing to one broker (rabbitmq)? 4.5.1 uses the newer rabbitmq client library, so not sure how the communication actually happens at the TCP level, from CloudStack’s side we simply make a connection using the java client/rabbitmq library. I would say, if you’re able to publish messages to it, you don’t need to worry about anything.
