Starlight for RabbitMQ metrics

Starlight for RabbitMQ exposes the following metrics in Prometheus format. You can monitor your clusters with these metrics.

The Starlight for RabbitMQ metrics are exposed under /metrics at port 8000 along with Pulsar metrics. To use a different port, configure the stats_server_port system property.

Metric types

Starlight for RabbitMQ metrics are either counters or gauges:
