在 Azure 監視器中建立記錄搜尋警示規則的 Resource Manager 範本範例

本文包含 Azure Resource Manager 範本範例,可用來在 Azure 監視器中建立和設定記錄搜尋警示。 每個範例都包含範本檔案和參數檔案,且附有要提供給範本的範例值。

注意

如需 Azure 監視器的可用範例清單,以及在 Azure 訂用帳戶中的部署指引,請參閱 Azure Resource Manager 範例

注意

記錄警示規則屬性中所有資料的大小總和不可超過 64 KB。 原因可能是維度太多、查詢太大、動作群組太多或描述過長。 建立大型警示規則時,請記得將這些區域最佳化。

所有資源類型的範本 (始於 2021-08-01 版)

下列範例會建立可將任何資源設為目標的規則。
