How to get the REAL hostname with Powershell (or Graph API)

Hi svhelden 

You can list the Azure VM's with their corresponding hostname via the following procedure.

Create the following Powershell script (yes only the 'hostname' command) on your computer and save it as 'hostname.ps1'

Hostname

Then create the 'list-hostname.ps1' Powershell script (Make sure to edit the X):

# #Azure Subscription I want to use
$subscriptionId = "XXXXXX-XXX-XXXX-XXXX-XXXXXXXXXXXX"
#Resource Group my VMs are in
$resourceGroup = "XXXX"

#Select the right Azure subscription
Set-AzContext -Subscription $subscriptionId

#Get all Azure VMs which are in running state and are running Windows
$myAzureVMs = Get-AzVM -ResourceGroupName $resourceGroup -status | Where-Object {$_.PowerState -eq "VM running" -and $_.StorageProfile.OSDisk.OSType -eq "Windows"}

#Run the scirpt again all VMs in parallel
$myAzureVMs | ForEach-Object -Parallel {
    $out = Invoke-AzVMRunCommand `
        -ResourceGroupName $_.ResourceGroupName `
        -Name $_.Name  `
        -CommandId 'RunPowerShellScript' `
        -ScriptPath .\hostname.ps1 
    #Formating the Output with the VM name
    $output = $_.Name + " " + $out.Value[0].Message
    $output   
}

 After creating the scripts upload them to the Azure Cloud Shell.

Then execute the following command in the Cloud Shell:

.\hostname.ps1

.\list-hostname.ps1

And that's it! Now you have a list if VM names with their corresponding hostnames.

Please let me know if you run into any other issues.
