+# Prometheus Example
+
+See [Monitoring RabbitMQ in Kubernetes](https://www.rabbitmq.com/kubernetes/operator/operator-monitoring.html) for detailed instructions.
+
+If you deployed the [Prometheus Operator](https://github.com/prometheus-operator/prometheus-operator), make Prometheus scrape RabbitMQ nodes by:
+```shell
+kubectl apply -f rabbitmq-podmonitor.yaml
+```
+
+Alternatively, if you deployed the Prometheus Operator via the [kube-prometheus-stack](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack) Helm chart,
+set the values in [kube-prometheus-stack-values.yaml](kube-prometheus-stack-values.yaml) when installing / upgrading the Helm chart.
