Prometheus Trait

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

The creation of 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] --trait prometheus.[key2]=[value2] integration.groovy

The following configuration options are available:

Property Type Description

Property	Type	Description
prometheus.enabled	bool	Can be used to enable or disable a trait. All traits share this common property.
prometheus.port	int	The Prometheus endpoint port (default `9779`).
prometheus.service-monitor	bool	Whether a `ServiceMonitor` resource is created (default `true`).
prometheus.service-monitor-labels	string	The `ServiceMonitor` resource labels, applicable when `service-monitor` is `true`.
prometheus.configmap	string	To use a custom ConfigMap containing the Prometheus exporter configuration (under the `content` ConfigMap key). When this property is left empty (default), Camel K generates a standard Prometheus configuration for the integration.

prometheus.enabled

bool
