具有天蓝色监视器和条件的逻辑应用程序

Question

我用 logicAPP 创建了一个工作流。目标是在 VM 缺少补丁时通知团队。我在逻辑应用程序中使用 azure monitor 来设置查询。我决定在 Azure Monitor 之后放置一个条件，以了解查询表是否为空或有数据。如果表为空，则 logix 为 true ，因此不发送通知，如果为 false ，则发送通知。

当我运行时，我遇到了逻辑错误。通常，表没有数据，但在条件之后，函数 empty([my_table]) 返回 false 并向我发送结果通知（“查询未产生数据”）

有什么问题？？

谢谢

基于上述共享要求，我们创建了逻辑应用并在我们的本地环境中对其进行了测试，它运行良好。

下面是完整的逻辑代码：
