Prometheus monitoring

Service Monitor for Prometheus-Operator

Create a ServiceMonitor for Prometheus-Operator to automatically scrape Guard’s metrics endpoint.

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: guard
  labels:
    app: guard
spec:
  endpoints:
  - interval: 30s
    path: /metrics
    port: api
    scheme: https
    tlsConfig:
      insecureSkipVerify: true
  namespaceSelector:
    any: true
  selector:
    matchLabels:
      app: guard

If prometheus-operator and kube-prometheus is installed using CoreOS’s helm charts, the serviceMonitor can be defined in kube-prometheus’s values.yaml.

prometheus:
  serviceMonitors:
    - name: guard
      labels:
        prometheus: kube-prometheus
      selector:
        matchLabels:
          app: guard
      endpoints:
        - port: api
          interval: 30s
          path: /metrics
          scheme: https
          tlsConfig:
            insecureSkipVerify: true
      namespaceSelector:
        any: true
