Configure RabbitMQ exporter to generate Prometheus metrics

This topic explains how to install RabbitMQ exporter and the metrics and KPIs you receive.

For versions 3.8.0 and later

If you use version 3.8.0 and later, refer to the RabbitMQ installation instructions to enable the rabbitmq_prometheus plugin. After you enable the plugin, the metrics are available on port 15692 at the /metrics endpoint.

For versions earlier than 3.8.0

If you use versions earlier than 3.8.0, install rabbitmq exporter. This exporter is also as a Prometheus community helm chart.
