Skapa en klassisk måttaviseringsregel med en Resource Manager mall

  • Artikel

Varning

Den här artikeln beskriver hur du skapar äldre klassiska måttaviseringsregler. Azure Monitor har nu stöd för nyare måttaviseringar i nära realtid och en ny aviseringsupplevelse. Klassiska aviseringar dras tillbaka för offentliga molnanvändare. Klassiska aviseringar för Azure Government moln och Microsoft Azure som drivs av 21Vianet upphör den 29 februari 2024.

Den här artikeln visar hur du kan använda en Azure Resource Manager-mallför att konfigurera klassiska Azure-måttaviseringsregler. På så sätt kan du automatiskt konfigurera aviseringsregler för dina resurser när de skapas för att säkerställa att alla resurser övervakas korrekt.

De grundläggande stegen är följande:

  1. Skapa en mall som en JSON-fil som beskriver hur du skapar aviseringsregeln.
  2. Distribuera mallen med valfri distributionsmetod.

Nedan beskriver vi hur du skapar en Resource Manager mall först enbart för en aviseringsregel och sedan för en aviseringsregel när en annan resurs skapas.

Resource Manager mall för en klassisk måttaviseringsregel

Om du vill skapa en aviseringsregel med hjälp av en Resource Manager mall skapar du en resurs av typen Microsoft.Insights/alertRules och fyller i alla relaterade egenskaper. Nedan visas en mall som skapar en aviseringsregel.

Resource Manager mall för en resurs med en klassisk måttaviseringsregel

En aviseringsregel för en Resource Manager mall är oftast användbar när du skapar en aviseringsregel när du skapar en resurs. Du kanske till exempel vill se till att en "CPU % > 80"-regel konfigureras varje gång du distribuerar en virtuell dator. Det gör du genom att lägga till aviseringsregeln som en resurs i resursmatrisen för mallen för den virtuella datorn och lägga till ett beroende med hjälp av dependsOn egenskapen till VM-resurs-ID:t. Här är ett fullständigt exempel som skapar en virtuell Windows-dator och lägger till en aviseringsregel som meddelar prenumerationsadministratörer när processoranvändningen överstiger 80 %.
