Beispiele für Resource Manager-Vorlagen für Protokollsuchwarnungsregeln in Azure Monitor

  • Artikel

Dieser Artikel enthält Beispiele für Azure Resource Manager-Vorlagen zum Erstellen und Konfigurieren von Protokollsuchwarnungen in Azure Monitor. Jedes Beispiel umfasst eine Vorlagendatei und eine Parameterdatei mit Beispielwerten für die Vorlage.

Hinweis

Eine Liste mit verfügbaren Beispielen und Anleitungen zu deren Bereitstellung in Ihrem Azure-Abonnement finden Sie unter Beispiele für Resource Manager-Vorlagen für Azure Monitor.

Hinweis

Die kombinierte Größe aller Daten in den Eigenschaften der Protokollbenachrichtigungsregel darf 64 KB nicht überschreiten. Dies kann durch zu viele Dimensionen verursacht werden, die Abfrage ist zu groß, zu viele Aktionsgruppen oder eine lange Beschreibung. Denken Sie beim Erstellen einer großen Warnungsregel daran, diese Bereiche zu optimieren.

Eine Vorlage für alle Ressourcentypen (ab Version 2021-08-01)

Im folgenden Beispiel wird eine Regel erstellt, die eine beliebige Ressource als Ziel haben kann:

  4

param alertSeverity int = 3

@description('Specifies whether the alert is enabled')
param isEnabled bool = true
