Camel K Prometheus Trait

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:

In case the prometheus operator is not installed in your cluster, run:

kamel run --dev --trait prometheus.enabled=true --trait prometheus.pod-monitor=false MyIntegration.java

Alternatively, you can quickly deploy the Prometheus operator and then run:

kubectl create -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/main/bundle.yaml

kamel run --dev --trait prometheus.enabled=true MyIntegration.java

The metrics can be retrieved by port-forwarding this service, e.g.:

kubectl port-forward svc/prometheus-operator 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.
