That was me! and yes you can do it when consuming notifications with ceilometer-agent-notification
Eg in our ceilometer.conf we have [notification] workers=12 disable_non_metric_meters=true store_events = true batch_size = 50 batch_timeout = 5 messaging_urls = rabbit://XX:XX@rabbithost1:5671/vhost1 <rabbit://XX:XX@rabbithost1:5671/vhost1> messaging_urls = rabbit://XX:XX@rabbithost2:5671/vhost <rabbit://XX:XX@rabbithost2:5671/vhost>2 messaging_urls = rabbit://XX:XX@rabbithost3:5671/vhost3 If no messaging_urls are set then it will fall back to the settings in the [oslo_messaging_rabbit] config section Also if you set messaging_urls then it won’t consume from the rabbit specified in [oslo_messaging_rabbit] so you have to add it to messaging_urls too.
