Ejemplos de plantillas de Azure Resource Manager para reglas de alertas de búsqueda de registros en Azure Monitor

  • Artikulua

Este artículo incluye ejemplos de plantillas de Azure Resource Manager para crear y configurar alertas de búsqueda de registros en Azure Monitor. Cada ejemplo incluye un archivo de plantilla y un archivo de parámetros con valores de ejemplo para la plantilla.

Nota

Consulte ejemplos de Azure Resource Manager de Azure Monitor para obtener una lista de ejemplos disponibles y orientación sobre cómo implementarlos en la suscripción de Azure.

Nota:

El tamaño combinado de todos los datos de las propiedades de la regla de alerta de registro no puede superar los 64 KB. Esto puede deberse a que haya demasiadas dimensiones, a que la consulta sea demasiado grande, a que haya demasiados grupos de acciones o a que la descripción sea muy larga. Al crear una regla de alerta grande, recuerde optimizar estas áreas.

Plantilla para todo tipo de recursos (a partir de la versión 2021-08-01)

En el ejemplo siguiente se crea una regla que puede tener como destino cualquier recurso.

Plantilla de número de resultados (hasta la versión 2018-04-16)

Notas

  • En este ejemplo se incluye una carga de webhook. Si la regla de alerta no debe desencadenar un webhook, quite el elemento customWebhookPayload.
