azure - 如何让 Azure Logic 应用发送电子邮件

Question

我使用本教程创建了一个逻辑应用程序，只要资源发生更改，它就会通过我的 gmail 帐户向我的工作帐户发送电子邮件：

https://docs.microsoft.com/en-us/azure/event-grid/monitor-virtual-machine-changes-event-grid-logic-app

但是，出于某种原因，每当我更改虚拟机上的任何内容时，例如停止/启动它，什么都不会发生。当我尝试手动运行触发器时，它会失败并显示以下消息：

无法启动逻辑应用 newLogicApp 的运行。处理您的请求时出错。请稍后重试。

我所有的资源都在同一个订阅下的同一个资源组中。

资源组中没有任何应用服务计划。我不知道这是否需要，如果需要，如何将该应用服务计划链接到逻辑应用本身。

这是逻辑应用的代码视图：

Answer 1

根据我的理解，本教程只是帮助我们如何监控虚拟机的变化，但不能监控虚拟机的启动/停止。我在 Azure 门户上对其进行了测试，如果启动/停止 VM，将不会触发逻辑应用。但是当我调整 VM 的大小时，逻辑被成功触发。你可以自己再测试一次。

顺便说一句，如果您想在 VM 启动时收到通知，您可以使用其他解决方案。转到您的虚拟机并单击“警报”->“新警报规则”。然后您可以添加“启动虚拟机”条件（另一个可能对您有帮助的条件是“创建或更新虚拟机”），并创建操作组以向自己发送电子邮件。（如下图所示）

更新：

看来（从您的查看代码）您的逻辑应用程序中的触发器（发生资源事件时）中没有添加“事件类型项”，您分享的教程中提到了它，您可以再次查看或参考我在下面发布的屏幕截图。
