平台侧自身复杂度变高， 监控难度加大 从 Kubernetes 架构来 看要监控的组件 Kubernetes架构 l 服务端组件，控制面：API Server、Scheduler、 Controller-Manager、ETCD l 工作负载节点，最核心就是监控Pod容器和节点本 身，也要关注 kubelet 和 kube-proxy l 业务程序，即部署在容器中的业务程序的监控，这 个其实是最重要的 随着 Kubernetes Pod的数量，gauge类型 • kubelet_running_containers：运行的容器的数量，gauge类型， container_state标签来区分容器状态 • volume_manager_total_volumes：volume的数量，gauge类型，state标签用 于区分是actual还是desired • kubelet_runtime_operations_total： controller-manager的监控 • controller-manager 通过 /metrics 接口暴露监控数据， 直接拉取即可 • controller-manager 在 Kubernetes 架构中，是负责监听 对象状态，并与期望状态做对比，如果状态不一致则进行 调谐，重点关注的是各个controller的运行情况，比如任 务数量，队列深度 • controller-manager出问题的概率相对较小，进程层面没
