<div dir="ltr"><div>Hello,</div><div> </div><div>Is there a way to determine a queue's size in bytes? I'm mostly interested in size on disk, but the sum of memory and disk would be sufficient if that happens to be more readily available.</div>
<div> </div><div>My scenario is as follows:</div><div>- We're using RabbitMQ 2.8.7 in a 2-node cluster (and in the process of upgrading to 3.1.x in a couple months)</div><div>- We have several groups of publishers publishing messages of varying sizes (from 10KB up to 3MB)</div>
<div>- Many messages and queues are configured in the worst-case (no message ttls, persistent messages, durable and mirrored queues, no queue length limit), and we're not in a position to change that in the short-term</div>
<div>- From time to time, we have absentee consumers that cause our RabbitMQ disk usage to climb towards the disk threshold</div><div> </div><div>At the point that disk usage starts to climb, we would like to be able to mitigate the inevitable disk alarm by identifying the queues containing the most data and unbind or purge them. If the messages were a uniform size, we could look at the queue depths and know which queues are consuming the most disk space, but given the varying message sizes of our scenario, the queue depth doesn't give us enough information to work with. Programmatically responding would be great, but manually manipulating the queues in the management UI would suffice for our immediate needs.</div>
<div> </div><div>Any recommendations or ideas would be greatly appreciated.</div><div> </div><div>On a related note, would it be possible for some future version of RabbitMQ to allow queue policies like "x-max-length" and "x-message-ttl" in addition to the queue declaration arguments?</div>
<div> </div><div>Thanks a lot,</div><div>Joe</div></div>
