Azure Monitor 中的默认 Prometheus 指标配置

  • 项目

本文列出了将 Prometheus 指标配置为从任何 Azure Kubernetes 服务 (AKS) 群集中抓取时的默认目标、仪表板和记录规则。

最小引入配置文件

Minimal ingestion profile 是一种有助于减少指标引入量的设置，因为只有默认仪表板使用的指标，才会收集默认记录规则和默认警报。 对于基于加载项的集合，Minimal ingestion profile 设置默认处于启用状态。 可以修改集合以启用收集更多指标，如下所示。

抓取频率

所有默认目标和抓取的默认抓取频率为 30 秒。

默认抓取的目标

以下目标默认处于“已启用/开启”状态，这意味着你不必提供任何抓取作业配置来抓取这些目标，因为指标加载项默认会自动抓取这些目标

  • cadvisor (job=cadvisor)
  • nodeexporter (job=node)
  • kubelet (job=kubelet)
  • kube-state-metrics (job=kube-state-metrics)
  • controlplane-apiserver (job=controlplane-apiserver)
  • controlplane-etcd (job=controlplane-etcd)

从默认目标收集的指标

默认情况下，将从每个默认目标收集以下指标。 所有其他指标都将通过重新标记规则删除。

默认抓取的 Windows 目标

以下 Windows 目标配置为抓取，但默认情况下抓取未启用（已禁用/关闭），这意味着你不必提供任何抓取作业配置来抓取这些目标，但它们默认处于禁用/关闭状态，你需要使用 default-scrape-settings-enabled 部分下的 ama-metrics-settings-configmap 为这些目标开启/启用抓取

可以针对 Windows 运行两个默认作业，这些作业将抓取特定于 Windows 的仪表板所需的指标。

  • windows-exporter (job=windows-exporter)
  • kube-proxy-windows (job=kube-proxy-windows)

注意

这需要应用或更新 ama-metrics-settings-configmap configmap 并在所有 Windows 节点上安装 windows-exporter。 有关详细信息，请参阅启用文档。
