10.2. 向 Prometheus 公开 Data Grid Metrics

添加从 Data Grid 向 Prometheus 公开 JMX 指标的服务。

  1. 创建一个 service-metrics.yaml 文件来定义指标服务。

    apiVersion: v1
    kind: Service
    metadata:
      annotations:
        description: Expose Data Grid metrics to Prometheus.
      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:
        deploymentConfig: datagrid-service
      sessionAffinity: None
  2. 应用 service-metrics.yaml

    $ oc apply -f service-metrics.yaml
