在 OpenShift Container Platform 4.11 中，集群组件的监控方式是提取通过服务端点公开的指标。您还可以为用户定义的项目配置指标集合。
您可以通过在应用程序级别使用 Prometheus 客户端库来定义您要为您自己的工作负载提供的指标。
在 OpenShift Container Platform 中，指标通过 /metrics 规范名称下的 HTTP 服务端点公开。您可以通过针对 http://<endpoint>/metrics 运行 curl 查询来列出服务的所有可用指标。例如，您可以向 prometheus-example-app 示例服务公开路由，然后运行以下命令来查看其所有可用指标：
curl http://<example_app_endpoint>/metrics
$ curl http://<example_app_endpoint>/metrics输出示例
