Collect details about all VMs in a subscription with PowerShell

This script creates a csv that contains the VM Name, Resource Group Name, Region, Vm Size, Virtual Network, Subnet, Private IP Address, OS Type, and Public IP Address of the VMs in the provided subscription.

If you don't have an Azure subscription, create a free account before you begin.

Launch Azure Cloud Shell

The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com/powershell. Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press enter to run it.

Sample script

#Provide the subscription Id where the VMs reside
$subscriptionId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

#Provide the name of the csv file to be exported
$reportName = "myReport.csv"

Select-AzSubscription $subscriptionId
$report = @()
$vms = Get-AzVM
$publicIps = Get-AzPublicIpAddress 
$nics = Get-AzNetworkInterface | ?{ $_.VirtualMachine -NE $null} 
foreach ($nic in $nics) { 
    $info = "" | Select VmName, ResourceGroupName, Region, VmSize, VirtualNetwork, Subnet, PrivateIpAddress, OsType, PublicIPAddress, NicName, ApplicationSecurityGroup 
    $vm = $vms | ? -Property Id -eq $nic.VirtualMachine.id 
    foreach($publicIp in $publicIps) { 
        if($nic.IpConfigurations.id -eq $publicIp.ipconfiguration.Id) {
            $info.PublicIPAddress = $publicIp.ipaddress
            } 
        } 
        $info.OsType = $vm.StorageProfile.OsDisk.OsType 
        $info.VMName = $vm.Name 
        $info.ResourceGroupName = $vm.ResourceGroupName 
        $info.Region = $vm.Location 
        $info.VmSize = $vm.HardwareProfile.VmSize
        $info.VirtualNetwork = $nic.IpConfigurations.subnet.Id.Split("/")[-3] 
        $info.Subnet = $nic.IpConfigurations.subnet.Id.Split("/")[-1] 
        $info.PrivateIpAddress = $nic.IpConfigurations.PrivateIpAddress 
        $info.NicName = $nic.Name 
        $info.ApplicationSecurityGroup = $nic.IpConfigurations.ApplicationSecurityGroups.Id 
        $report+=$info 
    } 
$report | ft VmName, ResourceGroupName, Region, VmSize, VirtualNetwork, Subnet, PrivateIpAddress, OsType, PublicIPAddress, NicName, ApplicationSecurityGroup 
$report | Export-CSV "$home/$reportName"
