How can i get the output of a CustomScriptExtenstion when using Azure Resource Manager?

I am using an Azure PowerShell Runbook to execute a PowerShell script on an Azure virtual machine. I do not find a way to get the output of the remote script when I'm using the Azure resource manager functions, which I have to use for my deployment. There are a lot examples using the 'non-resource manager' way, which looks like this:

# Execute remote script
$Vm = Get-AzureVM -ServiceName "DSCDemo" -Name "DSCPull"
Set-AzureVMCustomScriptExtension -ContainerName scripts -StorageAccountName psmag -FileName user.ps1 -Run user.ps1 -VM $vm | Update-AzureVM -Verbose
# Get output
$vm = Get-AzureVM -ServiceName DSCDemo -Name DSCPull
$output = $Vm.ResourceExtensionStatusList.ExtensionSettingStatus

The $output variable then contains the standard and error output of the script that has been executed. The same code looks pretty similar for my resource manager version:

# Execute remote script
$vm = Get-AzureRmVM -Name "DSCPull" -ResourceGroupName $ResourceGroupName
$result = Set-AzureRmVMCustomScriptExtension -ResourceGroupName $ResourceGroupName `
                                                -VMName "DSCPull"  `
                                                -Name 'user' `
                                                -Location $vm.Location  `
                                                -StorageAccountName psmag  `
                                                -StorageAccountKey '<key>' `
                                                -FileName "user.ps1"  `
                                                -ContainerName "scripts"  `
                                                -RunFile "user.ps1"
$output = Get-AzureRmVM -Name $VMName -ResourceGroupName $ResourceGroupName -Status

But the output is completely different and I do find anything that contains the standard output or error output.

How do I retrieve the output with help of the Azure resource manager functions?

In my testing, it can also be retrieved using Get-AzureRmVMExtension, which is arguably the more logical one to use. You must include the -Status parameter, else you don't get the status and substatus values back.

Also, if retrieving it in the output section of a Resource Manager template, something like this works (although I'm not fond of the hard-coded zero index):

"outputs": {
    "foo": {
        "type": "string",
        "value": "[reference('Microsoft.Compute/virtualMachines/my-vm/extensions/my-script').instanceView.substatuses[0].message)]"
    }
}

OK, I found the answer! You can always query the result with help of the Get-AzureRmVmDiagnosticExtension command:

$output = Get-AzureRmVMDiagnosticsExtension -ResourceGroupName $ResourceGroupName -VMName 'DSCPull' -Name 'user' -Status
$output.SubStatuses[0]
$output.SubStatuses[1]

Will return something like

Code          : ComponentStatus/StdOut/succeeded
Level         : Info
DisplayStatus : Provisioning succeeded
Message       : my output on remote
Time          :


Code          : ComponentStatus/StdErr/succeeded
Level         : Info
DisplayStatus : Provisioning succeeded
Message       :
Time          :
