Standardkonfiguration av Prometheus-mått i Azure Monitor

I den här artikeln visas standardmålen, instrumentpanelerna och inspelningsreglerna när du konfigurerar Prometheus-mått som ska skrapas från ett Azure Kubernetes Service-kluster (AKS) för alla AKS-kluster.

Standardmål som skrapats för Windows

Följande Windows-mål är konfigurerade för att skrapa, men skrapning är inte aktiverat (inaktiverat/AV) som standard , vilket innebär att du inte behöver ange någon konfiguration för skrapjobb för att skrapa dessa mål, men de är inaktiverade/AV som standard och du måste aktivera/aktivera skrapning för dessa mål med hjälp av ama-metrics-settings-configmap under default-scrape-settings-enabled avsnittet

Två standardjobb kan köras för Windows som skrapar mått som krävs för de instrumentpaneler som är specifika för Windows.

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

Anteckning

Detta kräver att konfigurationskartan ama-metrics-settings-configmap tillämpas eller uppdateras och installeras windows-exporter på alla Windows-noder. Mer information finns i dokumentet om aktivering.

Instrumentpaneler

Följande standardinstrumentpaneler etableras och konfigureras automatiskt av Den hanterade Azure Monitor-tjänsten för Prometheus när du länkar din Azure Monitor-arbetsyta till en Azure Managed Grafana-instans. Källkoden för dessa instrumentpaneler finns på den här GitHub-lagringsplatsen. Instrumentpanelerna nedan etableras i den angivna Azure Grafana-instansen under Managed Prometheus mappen i Grafana. Det här är standardinstrumentpanelerna öppen källkod community för övervakning av Kubernetes-kluster med Prometheus och Grafana.

• Kubernetes / Compute Resources / Namespace (Pods)
• Kubernetes / Compute Resources / Node (Pods)
• Kubernetes / Compute Resources / Pod
• Kubernetes / Compute Resources / Namespace (Workloads)
• Kubernetes / Compute Resources / Workload
• Kubernetes / Kubelet

Inspelningsregler

Följande standardregler för inspelning konfigureras automatiskt av Azure Monitor-hanterad tjänst för Prometheus när du länkar din Azure Monitor-arbetsyta till en Azure Managed Grafana-instans. Källkoden för dessa inspelningsregler finns på den här GitHub-lagringsplatsen. Det här är standardreglerna öppen källkod inspelning som används i instrumentpanelerna ovan.
