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` | ### rabbitmq\_connections\_opened\_total Total number of connections opened **Unit:** Number · **Type:**
