Azure Monitor 中的默认 Prometheus 指标配置
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。

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。

当启用 windows-exporter 和 kube-proxy-windows 时,将收集以下指标。

仪表板
当你将 Azure Monitor 工作区链接到 Azure 托管 Grafana 实例时,适用于 Prometheus 的 Azure Monitor 托管服务将自动预配和配置以下默认仪表板。 这些仪表板的源代码可在此 GitHub 存储库中找到。 以下仪表板将在 Grafana 中 Managed Prometheus
文件夹下的指定 Azure Grafana 实例中预配。 这些是标准开放源代码社区仪表板,可通过 Prometheus 和 Grafana 监视 Kubernetes 群集。

当你配置要从 Azure Kubernetes 服务 (AKS) 群集中抓取的 Prometheus 指标时,适用于 Prometheus 的 Azure Monitor 托管服务会自动配置以下默认记录规则。 这些记录规则的源代码可在此 GitHub 存储库中找到。 这些是上述仪表板中使用的标准开放源代码记录规则。
