注意点

  1. prometheus 抓取 node_exporter 指标的配置默认使用 https://github.com/prometheus-community/helm-charts/blob/prometheus-25.8.2/charts/prometheus/values.yaml#L896-L935 ，需要对 __meta_kubernetes_pod_node_name label 进行 replace 替换为 node label 的操作

  2. prometheus 需要抓取 kubelet 上暴露的 cadvisor 指标 https://github.com/prometheus-community/helm-charts/blob/prometheus-25.8.2/charts/prometheus/values.yaml#L835-L874

  3. 需要部署 kube-state-metrics 提供 kube_ 相关指标
