In this section you will find examples about fine tuning your Integration
using Prometheus trait
capability.
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 via:
$ kamel run -t prometheus.enabled=true MyIntegration.java
In case the prometheus operator is not installed in your cluster, run:
$ kamel run -t prometheus.enabled=true pod-monitor=false 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 documentation.
