Auto Shutdown ASM Virtual Machines in Azure | Azure Automation

I put together a quick script to auto shutdown tagged ARM VMs.

There are many people still running ASM VMs and why wouldn’t you they are still supported (as of 9/2016).

The process is not much different and in fact now Azure Automation enables a RunAs account at set up its much easier to configure.

In the example below I have tacked on changes to the Azure Automation Team’s sample script, one of four created for you when you enable the feature.

<# .DESCRIPTION An example runbook which gets all the Classic VMs in a subscription using the Classic Run As Account (certificate) and then shuts down running VMs .NOTES AUTHOR: Azure Automation Team + Jonathan Wade LASTEDIT: 28-08-2016 #>

$ConnectionAssetName = "AzureClassicRunAsConnection"
$ServiceName = "wadeclassiv01"
	
# Get the connection
$connection = Get-AutomationConnection -Name $connectionAssetName        

# Authenticate to Azure with certificate
Write-Verbose "Get connection asset: $ConnectionAssetName" -Verbose
$Conn = Get-AutomationConnection -Name $ConnectionAssetName
if ($Conn -eq $null)
{
    throw "Could not retrieve connection asset: $ConnectionAssetName. Assure that this asset exists in the Automation account."
}

$CertificateAssetName = $Conn.CertificateAssetName
Write-Verbose "Getting the certificate: $CertificateAssetName" -Verbose
$AzureCert = Get-AutomationCertificate -Name $CertificateAssetName
if ($AzureCert -eq $null)
{
    throw "Could not retrieve certificate asset: $CertificateAssetName. Assure that this asset exists in the Automation account."
}

Write-Verbose "Authenticating to Azure with certificate." -Verbose
Set-AzureSubscription -SubscriptionName $Conn.SubscriptionName -SubscriptionId $Conn.SubscriptionID -Certificate $AzureCert 
Select-AzureSubscription -SubscriptionId $Conn.SubscriptionID

# Get cloud service
    
$VMs = Get-AzureVM -ServiceName $ServiceName

    # Stop each of the started VMs
    foreach ($VM in $VMs)
    {
		if ($VM.PowerState -eq "Stopped")
		{
			# The VM is already stopped, so send notice
			Write-Output ($VM.InstanceName + " is already stopped")
		}
		else
		{
			# The VM needs to be stopped
        	$StopRtn = Stop-AzureVM -Name $VM.Name -ServiceName $VM.ServiceName -Force -ErrorAction Continue

	        if ($StopRtn.OperationStatus -ne 'Succeeded')
	        {
				# The VM failed to stop, so send notice
                Write-Output ($VM.InstanceName + " failed to stop")
	        }
			else
			{
				# The VM stopped, so send notice
				Write-Output ($VM.InstanceName + " has been stopped")
			}
		}
    }

PowerShell to list ASM VMs, Size and CloudService | Azure

I’ve been asked several times now to help customers running IaaS VMs in the Classic mode (ASM Mode) analyse their resources.

The following will list your classic VMs out by CloudService, VMName and VMSize to a CSV file.

You’ll need to edit the location of the file.

Please note this is not meant to be a very sophisticated script just to get you to the answer.

Happy hunting!


Add-AzureAccount
$services = Get-AzureVM | Group-Object -Property ServiceName
foreach ($service in $services)
{
   $out = @()
foreach ($VM in $service.Group)
{ 
$VMSizes = $VM.InstanceSize 

    $props = @{
        Cloudservice = $service.Name        
        VMName = $VM.Name
        VMSizes = $VMSizes
        }
    
    $out += New-Object PsObject -Property $props
}
   $out | Format-Table -AutoSize -Wrap CloudService, VMName, VMSizes
   $out | Export-Csv c:\scripts\test.csv -append
}
