title: Checking whether RabbitMQ cluster is idle or not
body: <p>I have got a task to check whether created RabbitMQ cluster is idle(has been used) or not. I can think of only one case which is non existence of queues and exchanges. If no queues are created then we can easily say that the created cluster has not been used. But my task is to collect all such cases by which we can check if created cluster is idle or been used.So I want everyone to help me to get more cases or situations where a RabbitMQ cluster will not be active for some time  and be idle.</p>
