+# Camel K Prometheus Trait
+
+In this section you will find examples about fine tuning your `Integration` using **Prometheus** `trait` capability.
+
+Run the integration via:
+
+    $ kamel run -t prometheus.enabled=true Hello.java
+
+A Prometheus-compatible endpoint is configured with the Prometheus trait. When utilising the Prometheus operator, it also generates a PodMonitor resource, which allows the endpoint to be scraped automatically.
+
+
+To get statistics about the number of events successfully handled by the `Integration`,execute the `MyIntegration.java` route individually via:
+
+    $ kamel run -t prometheus.enabled=true MyIntegration.java
+
+You should be able to see the new integration running after a while via:
+
+    $ kamel get 
+
+The metrics can be retrieved by port-forwarding this service, e.g.:
+
+    $ kubectl port-forward svc/metrics-prometheus 8080:8080
+
+    $ curl http://localhost:8080/metrics
+
+Similarly other use cases can be to retrieve information on unprocessed events, number of retries made to process an event, etc. For more information on Integration monitoring refer to the [Camel K Integration Monitoring](https://camel.apache.org/camel-k/1.8.x/observability/monitoring/integration.html) documentation.
