Opsview uses messages for all communication between all micro-services, this is based on RabbitMQ. The component is installed into `/opt/opsview/messagequeue`.

You can see what queues are set up and in use on the current server by using the following command (each Opsview Monitor server has its own message queue).

There is also a UI available for RabbitMQ, but you need to use an SSH tunnel to access it

You can then use http://localhost:15672 to access the UI and log in using the opsview user credentials stored within the deploy configuration on the Orchestrator.
