Steps to deploy RabbitMQ cluster

currently i am working on my local machine. so no cluster.

Steps to reproduce the behavior in question

1. run rabbitmq
2. publish some data
3. try to stop acknowledging messages
4. so now you will get unacknowledged messages

advanced.config

What problem are you trying to solve?

Hi all,

RabbitMQ 3.9.13
Erlang 24.2.1

I want rabbitmq metrics queue wise. I tried using rabbitmq promethues plugin, which gives me metrics for example "rabbitmq_queue_messages_unacked", but it is not queue wise. Let me know if you need more details. I want this to create an alerts if rabbitmq_queue_messages_unacked messages goes above some specific thresholds.

Thank you in advance.

Hi

First of all please upgrade RabbitMQ from the very old and officially not supported 3.9. At least since version 3.10 RabbitMQ has a prometheus plugin bundled. Check out the documentation of the /metrics/per-object endpoint which has per queue metrics. https://www.rabbitmq.com/docs/prometheus#per-object-endpoint. (With recent RabbitMQ versions I'd suggest to use the /metrics/detailed endpoint which also has per queue metrics but supports selecting only the "metric families" you need, this way reducing the overhead, size, etc of returning the metrics https://www.rabbitmq.com/docs/prometheus#detailed-endpoint)

Hi sir,
Thank you for the reply.

1. With Prometheus https://www.rabbitmq.com/docs/prometheus#metric-aggregation
2. GET /api/queues/{vhost}/{name} (this is from memory, see HTTP API docs at /api on any node with the management plugin

Absolutely NOT to do: GET /api/queues to then get one metric of one queue. That will render 70 metrics per queue, so, 70K rows for 1000 queues.
