10.3. 启用 Prometheus 以监控 Data Grid

服务监控器可让 Prometheus 连接到 Data Grid 指标服务。

  1. 创建一个 service-monitor.yaml 文件，其中包含 ServiceMonitor 对象的定义。 

    apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: datagrid-service-monitor
  labels:
    team: frontend
spec:
  selector:
    matchLabels:
      metrics: datagrid
  endpoints:
      # Set the name of the port where Data Grid publishes metrics.
      # You create this port in service-metrics.yaml.
    - port: web

  2. 应用 service-monitor.yaml。 

    $ oc apply -f service-monitor.yaml
