You can migrate selected Virtual Machines in a Hyper-V Cluster with following script.
That will migrate all virtual machines into target volume.
If target volume is not specified, it will look for best available CSV volume, and migrate virtual machine into that.

# Target Volume
$TargetVolume = "Volume1"
 
# Create VM Array
$VMArray = New-Object System.Collections.ArrayList
$VMArray.Clear();
 
$AddArray = $VMArray.Add("VM01")
$AddArray = $VMArray.Add("VM02")
$AddArray = $VMArray.Add("VM03")
 
# Get Cluster Nodes
$ClusterNodes = Get-Cluster | Get-ClusterNode
 
foreach ($ClusterNode in $ClusterNodes)
{
	# Get All Virtual Machines
	$VMs = Get-VM -ComputerName "$ClusterNode"
 
	foreach ($VM in $VMs)
	{
		# Get VM Information
		$VMName = $VM.Name
 
		if ($VMArray.Contains($VMName) -eq $True)
		{ 
			Write-Host " "
			Write-Host "Working on $VMName .."
			Write-Host "Hyper-V Host: $ClusterNode"
 
			if (!$TargetVolume)
			{
				# Get Volume Information
				$Volume = ((Get-ClusterSharedVolume | Select -ExpandProperty SharedVolumeInfo | Select @{label="Name";expression={(($_.FriendlyVolumeName).Split("\"))[-1]}},@{label="FreeSpace";expression={($_ | Select -Expand Partition).FreeSpace}} | Sort FreeSpace -Descending)[0]).Name
			}
			else
			{
				$Volume = $TargetVolume
			}
 
			# Move Virtual Machine
			Move-VMStorage -ComputerName "$ClusterNode" -VMName "$VMName" -DestinationStoragePath "C:\ClusterStorage\$Volume\$VMName"
 
			Write-Host "Done."
		}
	}
}

This script should work even if you have pass-through disks on virtual machine or virtual hba.

If you need to get Windows OS and Version information of a list of servers, then you can use following script.

1

$Servers = Get-Content Servers.txt
foreach ($Server in $Servers)
{
	$OSInfo = $Null;
	$CompInfo = $Null;
	$OSInfo = Get-WmiObject -ComputerName $Server -Class "Win32_OperatingSystem"
	$CompInfo = Get-WmiObject -ComputerName $Server -Class "Win32_ComputerSystem"
	$Value = $Server + ";" + $OSInfo.Caption + ";" + $OSInfo.CSDVersion + ";" + $OSInfo.BuildNumber + ";" + $OSInfo.Version + ";" + $CompInfo.Manufacturer + ";" + $CompInfo.Model
	Add-Content -Value $Value -Path ServerOSInfo.txt
}

That will output all data into ServerOSInfo.txt file.

		Write-Host Done.
	}
	else
    {
		Write-Host " "
		Write-Host Skipping $VMName ..
	}
}

This script should work even if you have pass-through disks on virtual machine or virtual hba.

If you need to increase memory of your virtual machines, you can use following script.

You need to create a txt file like:

VM01;2048
VM02;4096

Save it as Memory.txt and run following script:

1
2
3
4
5
6
7
8
9
10

$Servers = Get-Content Memory.txt
foreach ($Server in $Servers)
{
	$ServerName = $Server.Split(";")[0]
	$ServerName = $ServerName.Split(".")[0]
	$Memory = $Server.Split(";")[1]
	Stop-VM $ServerName
	Get-VM $ServerName | Set-VM -MemoryMB $Memory
	Start-VM $ServerName	
}

So that will stop VM, change memory and start VM again.

This is the third part of my Microsoft Azure VM Monitoring series. In the first part, I showed you how to simply monitor Azure VM with PowerShell. In the second part, we output all data into XML and parse it on a website.

Now we are moving forward.. Adding an autoscale function into our monitoring script. So, in a Azure VM farm, we have a stopped VM or VMs. We will monitor average CPU usage of all VMs in farm. If their CPU usage reaches to 40% percent, that will start our stopped VM to autoscale our web farm.

This is just an idea. You can use other metrics to autoscale your environment. For example, you can use IIS metrics to monitor website performance and start VMs if farm is under high web load.

Our autoscale part is here:

	# Autoscaling
	if ($VMTotalCPUUsage -gt "40")
	{
		# Get Azure Virtual Machines
		Get-AzureVM | Where ServiceName -eq "AzureWebFarm" | Where PowerState -eq "Stopped" | Start-AzureVM
	}

As you see, I started all VMs. But you can start VMs one by one or you can shutdown a VM if CPU usage is not high.

In the first part of our Azure Monitoring series, I showed you how to collect basic monitoring data from your Azure VMs. That was real time statistics but it was output everything on PowerShell console via Write-Host. It doesn’t make any sense because it’s not practical.

Now in this part, we will output all data into XML file, so you can use it on a website or on your CRM. You can also use .NET or PHP to parse XML data and put statistics onto website.

Following script is sample codes of VirtualMetric: Azure Module. You can check it from: http://www.virtualmetric.com

You will see xml files in the following directories. So you can make a website to parse that data.

This is demo page of VirtualMetric Azure Module:

http://virtualmetric.cloudapp.net/

You can download dashboard HTML files from here:

Download Azure Web Dashboard

That is a dashboard in realtime.

This is the first part of our Azure Monitoring script. It’s just a concept to show you how to monitor your Azure VM via PowerShell. Azure Powershell is not able to give performance data of virtual machines, so we will use remote PowerShell to connect Azure VMs.

My VMs are Windows Server 2012 R2, so Remote PowerShell is enabled by default on that servers. But if you are using earlier version of Windows, you should enable Remote PowerShell.

I simply used “Get-Credential” to get authenticated on Azure VMs but you can also store your password in a file as a plain text and use it to authenticate.

My Azure Subscriptions settings are in “Azure.Credentials.publishsettings” file. You can download it from Azure Website.

Following script is sample codes of VirtualMetric: Azure Module. You can check it from: http://www.virtualmetric.com
