json - 使用 Azure PowerShell 为 Azure Log Analytics 和基于指标的标准创建多个警报？

Question

假设我为 Azure 准备了一个通用模板文件来创建基于度量的警报，并为 2 个不同的度量警报（例如 CPU 利用率、内存使用）提供了 2 个单独的参数文件。

请参考我下面的模板文件示例，以及我打算运行的命令以通过 Powershell 创建这两种类型的警报。

有没有更好/更优雅的方式来做这件事（一个线性命令行）？我发现没有必要创建另一对文件来满足我希望监控的不同虚拟机的需求。

让我知道是否有任何文档可以在 Azure 网站上参考。

Azure CLI 命令：

az login

az group deployment create --name AlertTemplateDeployment --resource-group TestRscGrp --output tsv --template-file common_metricalert.template.json --parameters cpu_metricalert.parameters.json

az group deployment create --name AlertTemplateDeployment --resource-group TestRscGrp --output tsv --template-file common_metricalert.template.json --parameters memory_metricalert.parameters.json
