Azure 監視器中 Prometheus 計量的最小擷取設定檔

  • 文章

Azure 監視器計量附加元件依預設會收集許多 Prometheus 計量。 Minimal ingestion profile 是有助於降低計量擷取量的設定，因為只會收集預設儀表板、預設錄製規則與預設警示所使用的計量。 本文說明如何設定這項設定。 本文也會列出在 minimal ingestion profile 啟用時依預設收集的計量。 您可以修改收集以便收集更多計量，如下所示。

注意

對於以附加元件為基礎的收集，依預設會啟用 Minimal ingestion profile 設定。

依預設會啟用/開啟下列目標 - 這表示您不需要提供任何抓取作業設定來抓取這些目標，因為計量附加元件依預設會自動抓取這些目標

  • 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)

下列目標可供抓取，但依預設不會啟用抓取 (停用/關閉) - 這表示您不需要提供任何抓取作業設定來抓取這些目標，但依預設會加以停用/關閉，您必須使用 default-scrape-settings-enabled 區段底下的 ama-metrics-settings-configmap 為這些目標開啟/啟用抓取

  • 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

所有預設目標與抓取的預設抓取頻率為 30 seconds。 您可以使用 default-targets-scrape-interval-settings 區段下的 ama-metrics-settings-configmap，對每個目標覆寫此值。 控制平面目標的固定抓取間隔為 30 seconds，且無法覆寫。 您可以在這裡深入了解計量附加元件所使用的四個不同的設定對應

組態設定

預設會在計量附加元件上啟用此設定 default-targets-metrics-keep-list.minimalIngestionProfile="true"。 您可以在 default-targets-metrics-keep-list 區段下的 ama-metrics-settings-configmap 中指定此設定。

案例

有四種您可能想要自訂此行為的情節：

僅擷取每個預設目標的最小計量。
這是設定 default-targets-metrics-keep-list.minimalIngestionProfile="true" 的預設行為。 系統只會為每個預設目標擷取下列計量。

除了最小計量以外，還會擷取一或多個預設目標的一些其他計量。
保留 minimalIngestionProfile="true" 並指定該目標特有的適當 keeplistRegexes.*，例如 keeplistRegexes.coreDns="X``Y"。 X,Y 會與目標的預設計量清單合併，然後受到擷取。 ``

僅擷取一組特定的目標計量，而沒有其他項目。
設定 minimalIngestionProfile="false" 並在 ama-metrics-settings-configmap 中指定該目標特有的適當 default-targets-metrics-keep-list.="X``Y"。

擷取針對預設目標抓取的所有計量。
設定 minimalIngestionProfile="false" 且請勿為該目標指定任何 default-targets-metrics-keep-list.<targetname>。 變更為 false，可讓每個目標的計量擷取量倍增。

注意

up 計量不是允許/保留清單的一部分，因為不論是否指定 keepLists，都會針對每個目標在每次抓取時擷取該計量。 實際上不會抓取此計量，而是由計量附加元件的抓取作業產生的。 若是長條圖和摘要，清單中必須明確包含每個序列 (*bucket、*sum、*count 序列)。

預設 ON 目標的擷取下限

下列計量被允許列入預設 ON 目標的 minimalingestionprofile=true。 依預設會收集下列計量，因為預設會抓取這些目標。
