Przykłady szablonów usługi Resource Manager dla reguł alertów przeszukiwania dzienników w usłudze Azure Monitor

  • Artykuł

Ten artykuł zawiera przykłady szablonów usługi Azure Resource Manager do tworzenia i konfigurowania alertów wyszukiwania dzienników w usłudze Azure Monitor. Każdy przykład zawiera plik szablonu i plik parametrów z przykładowymi wartościami, które mają być udostępniane szablonowi.

Uwaga

Zobacz Przykłady usługi Azure Resource Manager dla usługi Azure Monitor, aby uzyskać listę dostępnych przykładów i wskazówki dotyczące wdrażania ich w ramach subskrypcji platformy Azure.

Uwaga

Łączny rozmiar wszystkich danych we właściwościach reguły alertu dziennika nie może przekraczać 64 KB. Może to być spowodowane zbyt dużą liczbą wymiarów, zbyt dużym zapytaniem, zbyt dużą liczbą grup akcji lub długim opisem. Podczas tworzenia dużej reguły alertu pamiętaj, aby zoptymalizować te obszary.
