Resource Manager-mallexempel för aviseringsregler för loggsökning i Azure Monitor

Den här artikeln innehåller exempel på Azure Resource Manager-mallar för att skapa och konfigurera aviseringar för loggsökning i Azure Monitor. Varje exempel innehåller en mallfil och en parameterfil med exempelvärden som ska tillhandahållas mallen.

Kommentar

Se Azure Resource Manager-exempel för Azure Monitor för en lista över exempel som är tillgängliga och vägledning om hur du distribuerar dem i din Azure-prenumeration.

Kommentar

Den kombinerade storleken på alla data i loggaviseringsregelns egenskaper får inte överstiga 64 KB. Detta kan orsakas av för många dimensioner, frågan är för stor, för många åtgärdsgrupper eller en lång beskrivning. När du skapar en stor aviseringsregel bör du komma ihåg att optimera dessa områden.

Mall för alla resurstyper (från version 2021-08-01)

I följande exempel skapas en regel som kan rikta sig mot valfri resurs.
