Service Monitor

The chart comes with a ServiceMonitor for use with the kube-pometheus-stack. If you're not using the Prometheus Operator, you can disable the ServiceMonitor by setting serviceMonitor.enabled to false and it will auto generate the following podAnnotations into deployment.yaml:

podAnnotations:
  prometheus.io/path: /metrics

  prometheus.io/scrape: "true"
