Esempi di modelli di Resource Manager per le regole di avviso di ricerca log in Monitoraggio di Azure

Questo articolo include esempi di modelli di Azure Resource Manager per creare e configurare gli avvisi di ricerca log in Monitoraggio di Azure. Ogni esempio include un file modello e un file di parametri con valori di esempio da fornire al modello.

Nota

Per un elenco di esempi disponibili e indicazioni sulla distribuzione nella sottoscrizione di Azure, vedere Esempi di Azure Resource Manager per Monitoraggio di Azure.

Nota

Le dimensioni combinate di tutti i dati nelle proprietà della regola di avviso del log non possono superare i 64 KB. Ciò può essere causato da troppe dimensioni, dalla query troppo grande, da troppi gruppi di azioni o da una descrizione lunga. Quando si crea una regola di avviso di grandi dimensioni, ricordarsi di ottimizzare queste aree.

Modello per tutti i tipi di risorse (dalla versione 2021-08-01)

L'esempio seguente crea una regola che può essere usata con qualsiasi risorsa.
