is exposing metrics. To do that you need to define a service that: is exposing metrics. To do that you need to define a service that:
* Exposes the exporter port * Exposes the exporter port
* Add the annotation: prometheus.io/scrape: "true" * Has a **prometheus.io/scrape: "true"** annotation
* Add the annotation: prometheus.io/port: "9090" * Has a **prometheus.io/port: "9090"** annotation
And you should be able to see your RabbitMQ exporter being scraped on Prometheus status page. And you should be able to see your RabbitMQ exporter being scraped on the Prometheus status page.
