“队列/主题中的死信消息计数。（预览版）”Azure

Question

对于我们的持续部署，我们希望为主题中的死信消息设置警报规则。在 Azure 门户上，此指标作为预览功能存在。我们希望通过 ARM 模板创建此警报规则。

在我的 ARM 模板参数中是否已经有一个指标名称可以用于此目的？ 如果没有，什么时候可以在我们的 ARM 模板中使用这个指标？

请参阅此处未列出指标名称：https://docs.microsoft.com/en-us/azure/azure-monitor/platform/metrics-supported#microsoftservicebusnamespaces

但可以手动创建警报规则并选择此指标：

这是用于创建度量警报Count of dead lettered messages in a Queue/Topic 的 ARM 模板：

将以下重要值传递给参数：

Metric Name : DeadletteredMessages
Time Aggregation : Average
Resource Id: Resource ID of your Service Bus Namespace. You can get this from the properties of the service bus blade as shown in below image

我意识到我忘记了 Azure 门户中的“导出模板”功能。手动创建警报规则或任何资源后，可以将资源组导出为 ARM 模板。在这里我可以找到包含模板内容的资源来生成手动创建的资源。
