RabbitMQ

RabbitMQ 3.8 and later include a Prometheus plugin. Enable it:

rabbitmq-plugins enable rabbitmq_prometheus

It listens on port 15692 by default:

curl -fsS http://127.0.0.1:15692/metrics | grep rabbitmq_build_info

Create conf/input.prometheus/rabbitmq.toml:

[[instances]]
urls = ["http://127.0.0.1:15692/metrics"]
url_label_key = "instance"
url_label_value = "{{.Host}}"
labels = { job = "rabbitmq" }

The 3.8/3.8+ dashboards were validated against built-in Prometheus metrics. Create exchanges and queues and publish/consume messages before checking rate and backlog panels.

For versions older than 3.8, enable rabbitmq_management and use Categraf's RabbitMQ input against port 15672. Its metric names differ, so use the matching legacy dashboard.
