Azure – What tags are we using again…?

Have you wondered what tags are assigned to all your Azure VMs?  Do you not have ARM Policies in place to enforce your preferred tags yet?

I was in just such a situation the other day.  Just like in my previous post on quick Azure-related scripts, I was working with a customer that just wanted a quick utility to report on what VMs are properly tagged (or not) in their implementation, without having to fish around the Portal.  No ARM Policies there yet…  *yet*.

So I whipped this together.  And much like that previous script, you just paste this into a PS1 file, set the subscription name in the variable, and then run it.

# GetVmTags - Jeremy Pavlov @ Coretek Services 
# Setting the subscription here
$MySubscriptionName = "My Subscription"
# Set some empty arrays
$vmobjs = @()
$vmTagsKeys = @()
$vmTagsValues = @()
# Get the VMs...
$vms = Get-AzureRmVm 
#
$NeedToLogin = Read-Host "Do you need to log in to Azure? (Y/N)"
if ($NeedToLogin -eq "Y")
{
  Login-AzureRmAccount
  Select-AzureRmSubscription -SubscriptionName $MySubscriptionName
}
elseif ($NeedToLogin -eq "N")
{
  Write-Host "You must already be logged in then.  Fine. Continuing..."
}
else
{
  Write-Host ""
  Write-Host "You made an invalid choice.  Exiting..."
  exit
}
#
foreach ($vm in $vms)
{
    Write-Host ""
    $vmname = $vm.name
    $MyResourceGroup = $vm.ResourceGroupName
    Write-Host "Checking tags for VM $vmname... "
    Start-Sleep 1
    $vmTags = (Get-AzureRmVM -name $vmname -ResourceGroupName $MyResourceGroup).Tags
    $vmTagsCount = $vmTags.Count
    if ($vmTagsCount -gt 0)
    {
      $vmTagsKeys = $vmTags.Keys -split '
[\r\n]' $vmTagsValues = $vmTags.Values -split '[\r\n]' for ($i=0;$i -lt $vmTagsCount; $i++) { $CurrentTagKey = $vmTagsKeys[$i] $CurrentTagValue = $vmTagsValues[$i] Write-Host -ForegroundColor Green "Key : Value -- $CurrentTagKey : $CurrentTagValue" } } else { Write-Host -ForegroundColor Yellow "No tags for $vmname" } }

The results should look something like this, except hopefully a lot more serious and business-y:

Have fun with it, change it up, and let me know what you do with it…   I hope it helps.  Enjoy!
