"Count of dead-lettered messages in a Queue/Topic. (Preview)" Azure 的指标名称

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。我们想通过 ARM 模板创建此警报规则。

我的 ARM 模板参数中是否已经有可以用于此目的的指标名称？如果不是，什么时候可以在我们的 ARM 模板中使用此指标？

请查看此处未列出的指标名称：https://docs.microsoft.com/en-us/azure/azure-monitor/platform/metrics-supported#microsoftservicebusnamespaces

但可以手动创建警报规则和 select 此指标：

这是用于创建指标警报的 ARM 模板Count of dead lettered messages in a Queue/Topic：

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 "Export Template" 功能。手动创建警报规则或任何资源后，资源组可以导出为 ARM 模板。在这里我能够定位到包含模板内容的资源以生成手动创建的资源。
