Is there any powershell script by which I can find utilization details of the disks attached to a particular virtual machine?

Question

I want to know how much is the free space and how much is the available space for all the disks present in a particular virtual machine ? FYI: The VM is present in Microsoft Azure.

Hello Tajman Kaur,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that you would like to have PowerShell script which can help you to find utilization details of the disks attached to a particular virtual machine in Azure.

Yes, there are scripts you can use PowerShell to find the utilization details of disks attached to a virtual machine in Microsoft Azure. This script below will connect to your Azure account, retrieve the specified VM, and run a PowerShell script inside the VM to get the disk utilization details, including the drive letter, total size, and free space for each disk - https://learn.microsoft.com/en-us/azure/virtual-machines/windows/tutorial-manage-data-disk

Follow the steps in the script's comments:

# Install the Azure PowerShell module** if you haven't already:
     Install-Module -Name Az -AllowClobber -Scope CurrentUser
# Connect to your Azure account**:
   Connect-AzAccount
# The following script will get the disk utilization details, start by define the VM details:
   $resourceGroupName = "YourResourceGroupName"
   $vmName = "YourVMName"
   
# Get the VM
   $vm = Get-AzVM -ResourceGroupName $resourceGroupName -Name $vmName
   
# Run a script inside the VM to get disk utilization details
   $script = @" Get-Volume | Select-Object DriveLetter, @{Name='Size(GB)';Expression=	 {[math]::round($_.Size/1GB,2)}}, @{Name='FreeSpace(GB)';Expression={[math]::round($_.SizeRemaining/1GB,2)}}
   "@
   
# Execute the script inside the VM
   $result = Invoke-AzVMRunCommand -ResourceGroupName $resourceGroupName -VMName $vmName -CommandId 'RunPowerShellScript' -ScriptString $script
   
# Display the result
   $result.Value[0].Message

I hope this is helpful! Do not hesitate to let me know if you have any other questions.
