Just what I needed, thanks Sam. And I can also confirm this works like a champ.
I was digging through oslo.messaging stuff looking for this, I completely overlooked the notification settings in ceilometer itself. Appreciate pointing me in the right direction!

The scenario here is we use the Ceilometer notification agent the pipe events from OpenStack services into a Kafka queue for consumption by other team(s) in the company. We also run Nova cells v1, so we have to run one Ceilometer agent for the API cell, as well as an agent for every compute cell (because they have independent RMQ clusters.) Anyway, I tried configuring it this way and it still only connects to a single RMQ server. We’re running Liberty Ceilometer and oslo.messaging, so I’m wondering if this behavior is only in a later version? Can anybody shed any light? I would love to get away from running so many Ceilometer agents. Thanks!
