  labels:
    app: datagrid-service
    application: datagrid-service
    template: datagrid-service
    metrics: datagrid
  name: datagrid-app-metrics
spec:
  ClusterIP: None
  ports:
      # Set the port name where Data Grid publishes metrics.
      # You add the port name to service-monitor.yaml.
    - name: web
      port: 8080
      protocol: TCP
      targetPort: 9779
  selector:
