Configurazione delle metriche predefinite di Prometheus in Monitoraggio di Azure

Questo articolo elenca le destinazioni, le regole di registrazione e i dashboard predefiniti quando si configurano le metriche di Prometheus per lo scorporamento da un cluster del servizio Azure Kubernetes per qualsiasi cluster del servizio Azure Kubernetes.

Profilo di inserimento minimo

Minimal ingestion profile è un'impostazione che consente di ridurre il volume di inserimento delle metriche, in quanto vengono raccolte solo le metriche usate dai dashboard predefiniti, le regole di registrazione predefinite e gli avvisi predefiniti. Per la raccolta basata su addon, Minimal ingestion profile impostazione è abilitata per impostazione predefinita. È possibile modificare la raccolta per abilitare la raccolta di altre metriche, come specificato di seguito.

Frequenza di scorporamento

La frequenza di scorporamento predefinita per tutte le destinazioni e gli scorporamenti predefiniti è 30 secondi.

Destinazioni scorporate per impostazione predefinita

Le destinazioni seguenti sono abilitate/ON per impostazione predefinita, ovvero non è necessario fornire alcuna configurazione del processo di scorporamento per scorporare queste destinazioni, perché il componente aggiuntivo Metriche scorporerà automaticamente queste destinazioni per impostazione predefinita.

Destinazioni predefinite scorporate per Windows

Le destinazioni di Windows seguenti sono configurate per lo scorporamento, ma lo scorporamento non è abilitato (disabilitato/OFF) per impostazione predefinita, ovvero non è necessario fornire alcuna configurazione del processo di scorporamento per lo scorporamento di queste destinazioni, ma sono disabilitate/OFF per impostazione predefinita ed è necessario impostare su ON/abilitare lo scorporamento per queste destinazioni usando ama-metrics-settings-configmap nella sezione default-scrape-settings-enabled.

Dashboard

Il servizio gestito per Prometheus di Monitoraggio di Azure effettua il provisioning e configura automaticamente i dashboard predefiniti seguenti quando si sceglie di collegare l'area di lavoro di Monitoraggio di Azure a un'istanza di Grafana con gestione Azure. Il codice sorgente per questi dashboard è disponibile in questo repository GitHub. Il provisioning dei dashboard seguenti verrà eseguito nell'istanza di Azure Grafana specificata nella cartella Managed Prometheus in Grafana. Questi sono i dashboard della community open source standard per il monitoraggio dei cluster Kubernetes con Prometheus e Grafana.
