Prometheus Event Source for Knative Eventing

The Prometheus Event Source enables Knative Eventing integration with the Prometheus Monitoring System.

At the moment the implementation supports only simple PromQL queries. The queries run against the Prometheus server every 5 seconds and the results are sent to the configured sink as CloudEvents.

Deployment steps

Setup Knative Eventing

Create a PrometheusSource CRD, specifying the URL for the Prometheus server, the PromQL query to run and the sink to send CloudEvents to:

apiVersion: sources.eventing.knative.dev/v1alpha1
kind: PrometheusSource
metadata:
  name: prometheus-source
spec:
  serverURL: http://demo.robustperception.io:9090
  promQL: ALERTS
  sink:
    apiVersion: serving.knative.dev/v1
    kind: Service
    name: event-display
