With the PowerShell collect details about all Azure VM's in a subscription!

MVP

 

Hi Microsoft Azure Friends,

 

I used the PowerShell ISE for this configuration. But you are also very welcome to use Visual Studio Code, just as you wish. Please start with the following steps to begin the deployment (the Hashtags are comments):

 

#The first two lines have nothing to do with the configuration, but make some space below in the blue part of the ISE

Set-Location C:\Temp
Clear-Host

 

#So that you can carry out the configuration, you need the necessary cmdlets, these are contained in the module Az (is the higher-level module from a number of submodules)

Install-Module -Name Az -Force -AllowClobber -Verbose

 

#Log into Azure
Connect-AzAccount

 

#Select the correct subscription

Get-AzContext

Get-AzSubscription

Get-AzSubscription -SubscriptionName "your subscription name" | Select-AzSubscription

 

#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"
 
#If you didn't select the subscription in the step above, you can do so now (or just skip it)
Select-AzSubscription $subscriptionId
 
#Some variables
$report = @()
$vms = Get-AzVM
$publicIps = Get-AzPublicIpAddress 
$nics = Get-AzNetworkInterface | ?{ $_.VirtualMachine -NE $null}
 
#Now start the loop
foreach ($nic in $nics) { 
    $info = "" | Select VmName, ResourceGroupName, Region, VirturalNetwork, Subnet, PrivateIpAddress, OsType, PublicIPAddress 
    $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.VirturalNetwork = $nic.IpConfigurations.subnet.Id.Split("/")[-3] 
        $info.Subnet = $nic.IpConfigurations.subnet.Id.Split("/")[-1] 
        $info.PrivateIpAddress = $nic.IpConfigurations.PrivateIpAddress 
        $report+=$info 
    } 
 
#Now let's look at the result    
$report | ft VmName, ResourceGroupName, Region, VirturalNetwork, Subnet, PrivateIpAddress, OsType, PublicIPAddress

#We save the file in our home folder
$report | Export-CSV "$home/$reportName"
 
Now you have used the PowerShell to create a report with the details about the vm's in a subscription! Congratulations!
 

I hope this article was useful. Best regards, Tom Wechsler
