Based on RabbitMQ's website, their library would need to be imported and configured within a Java application for the application to read from it. This isn't setup in Assure, so it wouldn't be possible via that avenue.
If RabbitMQ has REST API capability, then you could connect to it via Assure's REST API layout or DQ+'s REST API node. I found a few references of RabbitMQ having REST API online, although not any solid documentation on the REST API itself.
