I have a sensu server in AWS that is being used to monitor ec2 instances in multiple regions. I am using RabbitMQs shovel plugin to "shovel messages from the main Rabbit to Rabbits in other regions and back again. Using tcpdump, I have seen the message go from the sensu server to the local Rabbit to the remote Rabbit to the remote ec2 and all the way back to the sensu server. Unfortunately, any results coming from a remote Rabbit fail to trigger a handler. The results from the local ec2 instances work fine, just the remote ones fail. Anyone have any ideas what I should be looking at?
