在 Kusto 查询中显示 JSON 属性 - 特定子网

Question

你好，我有一个小问题，我在任何地方都找不到我能理解的答案。

我即将使用 Azure Resource Graph Explorer 及其 Kusto 查询语言在 azure 中制作仪表板，我想显示订阅中有多少个子网。

但是当我尝试分离并显示其中的子网时，它只显示存在的 Vnet 数量，或者显示一行子网而不是多少。

我已经尝试使用以下代码来投影子网，但不知道要写什么来显示包含两行名称为“子网”的单行以及其中的数量。

总结：是那个；我想编写一个 Kusto 查询，我可以将其固定到显示有多少子网的仪表板。

我尝试编写的代码：

resources
| project properties.subnets

输出为： properties_subnets

null
[{"type":"Microsoft.Network/virtualNetworks/subnets","properties":{"provisioningState":"Succeeded", etc. etc. etc.
