左侧这个配置大家在网上比较容易搜到，通过kubernetes_sd_configs做服务发现，查找所有node，通过 Kubernetes apiserver 的 proxy 接口，抓取各个node（即kubelet）的 /metrics/cadvisor 接口的 prometheus 协议的数据 • 这个抓取器只需要部署一个实例，调用 apiserver 的接口即可，维护较为简单，采集频率可以调的稍大，比 如30s或60s • apiserver，如果是几千个node的大集群，对 apiserver 可能会有较大压力 Kubernetes Node - 容器负载监控 抓取方案 { 抓取方案二 } • 直接调用 kubelet 的接口 /metrics/cadvisor ，不走 apiserver 这个 proxy，避免对 apiserver 的请求压力 • 采用 Daemonset 的方式部署 • 但是，缺少了对 __meta_kubernetes_node_label_( m]) Kubernetes Node - Kubelet监控 • Kubelet 在 /metrics/cadvisor 暴露的是 cAdvisor 的监控数据（prometheus协 议），在 /stats/summary 暴露的是容 器的概要监控数据（普通json协议）， 在 /metrics 暴露的是自身的监控数据 （prometheus协议） • Kubelet 的核心职责就是管理本机的
