用于 Azure Monitor 中 Prometheus 指标的最小引入配置文件

  • 项目

默认情况下，Azure Monitor 指标加载项会收集 Prometheus 指标的数量。 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。 本文介绍如何配置此设置。 本文还列出了启用 minimal ingestion profile 时默认收集的指标。 可以修改集合以启用收集更多指标，如下所示。

注意

对于基于加载项的集合，Minimal ingestion profile 设置默认处于启用状态。

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)

以下目标可进行抓取，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

  • core-dns (job=kube-dns)
  • kube-proxy (job=kube-proxy)
  • api-server (job=kube-apiserver)
  • controlplane-cluster-autoscaler (job=controlplane-cluster-autoscaler)
  • controlplane-kube-scheduler (job=controlplane-kube-scheduler)
  • controlplane-kube-controller-manager (job=controlplane-kube-controller-manager)

注意

所有默认目标和抓取的默认抓取频率为 30 seconds。 可以使用 default-targets-scrape-interval-settings 部分下的 ama-metrics-settings-configmap 替代每个目标。 控制平面目标具有固定的抓取间隔 30 seconds，且无法覆盖。 可在此处详细了解指标加载项使用的四种不同 configmap

配置设置

默认情况下，该设置 default-targets-metrics-keep-list.minimalIngestionProfile="true" 在指标加载项上处于启用状态。 可以在 default-targets-metrics-keep-list 部分下的 ama-metrics-settings-configmap 中指定此设置。

方案

在以下四种情况下，你可能希望自定义此行为:

每个默认目标仅引入最少指标。
这是设置 default-targets-metrics-keep-list.minimalIngestionProfile="true" 的默认行为。 对于每个默认目标，只引入下面列出的指标。

除了最少指标外，还为一个或多个默认目标引入一些其他指标。
保留 minimalIngestionProfile="true" 并指定特定于目标的相应 keeplistRegexes.* 对象，例如 keeplistRegexes.coreDns="X``Y"。 X,Y 与目标的默认指标列表合并，然后被引入。 ``

仅为目标引入一组特定的指标，而不引入其他指标。
设置 minimalIngestionProfile="false"，并指定特定于 ama-metrics-settings-configmap 中的目标的相应 default-targets-metrics-keep-list.="X``Y"。

引入为默认目标抓取的所有指标。
设置 minimalIngestionProfile="false" 并且不为该目标指定任何 default-targets-metrics-keep-list.<targetname>。 更改为 false 可能会使每个目标的指标引入量增加一个系数。

注意

up 指标不是允许/保留列表的一部分，不管指定的 keepLists 是什么，都会按每个抓取、每个目标引入指标。 此指标实际上不是抓取的，而是由指标加载项的抓取操作而生成的。 对于直方图和摘要，每个序列必须显式包含在列表中（*bucket、*sum 和 *count 序列）。

默认 ON 目标的最少引入

默认 ON 目标允许使用 minimalingestionprofile=true 列出以下指标。 默认情况下会收集以下指标，因为这些目标默认已抓取。
