azure - 如何监控Azure子网中的IP分配？

Question

我需要查找 Azure 子网内 IP 地址的当前使用情况。我在“虚拟网络”->“子网”中找到了空闲 IP，但该数字是子网内的可用 IP 地址总数。如何查看子网内有多少可用 IP 正在实际使用中(其中有多少是免费的)？有没有办法为 Azure 子网设置免费 IP 地址(或已用 IP 地址)的监视？提前致谢。

您可以调用listUsage API /subscriptions/****/resourceGroups/aoprod9574-stamp-canadacentral-rg/providers/Microsoft.Network/virtualNetworks/vnet-name/usages?api-version=2021-02-01 获取VNet 中每个子网的当前分配

{
  "value": [
    {
      "currentValue": 3,
      "id": "/subscriptions/****/resourceGroups/my-rg/providers/Microsoft.Network/virtualNetworks/aoprod9574-canadacen-vnet/subnets/cosmosdb-pe-snet",
      "limit": 27,
      "name": {
        "localizedValue": "Subnet size and usage",
        "value": "SubnetSpace"
      },
      "resourceGroup": "my-rg",
      "unit": "Count"
    },
    {
      "currentValue": 93,
      "id": "/subscriptions/****/resourceGroups/my-rg/providers/Microsoft.Network/virtualNetworks/aoprod9574-canadacen-vnet/subnets/kubernetes-snet",
      "limit": 1019,
      "name": {
        "localizedValue": "Subnet size and usage",
        "value": "SubnetSpace"
      },
      "resourceGroup": "my-rg",
      "unit": "Count"
    }
  ]
}
