RabbitMQ Metrics

Metrics groundcover collects from RabbitMQ.

Metrics groundcover collects from RabbitMQ by scraping the rabbitmq_prometheus plugin endpoint on each node. Each metric below is searchable by its exact name.

Labels are the dimensions you can slice these metrics by. Labels vary per metric group; identity metrics like rabbitmq_build_info and process metrics carry none of these:

Label	Description	Example values
vhost	Virtual host the object belongs to	/, production
queue	Queue name	my-queue
queue_type	Queue implementation type	classic, quorum, stream
exchange	Exchange name	amq.direct, my-exchange
channel	Channel identifier (Erlang process id)	<0.789.0>
protocol	Messaging protocol of the connection	amqp091, amqp10, mqtt, http
username	Authenticated user (auth / connection metrics)	guest
remote_address	Client source address (detailed auth metrics)	10.0.0.5
membership	Quorum-queue replica role	leader, follower, not_a_member
rabbitmq_node	RabbitMQ node the metric was scraped from	rabbit@node-1
rabbitmq_cluster	Cluster name	rabbit@cluster
