Is it possible to view RabbitMQ message contents directly from the command line?
sudo rabbitmqctl list_queues lists the queues.
Is there any comma
a bit late to this, but yes rabbitmq has a build in tracer that allows you to see the incomming messages in a log. When enabled, you can just tail -f /var/tmp/rabbitmq-tracing/.log (on mac) to watch the messages.
