Prometheus Trait

The Prometheus trait exposes the integration with a Service and a ServiceMonitor resources so that the Prometheus endpoint can be scraped.

Creating the ServiceMonitor resource requires the Prometheus Operator custom resource definition to be installed. You can set service-monitor to false for the Prometheus trait to work without the Prometheus operator.

It’s disabled by default.

This trait is available in the following profiles: Kubernetes, Knative, OpenShift.

Configuration

Trait properties can be specified when running any integration with the CLI:

kamel run --trait prometheus.[key]=[value] integration.groovy

The following configuration options are available:
