Updated document to include PS script to show VM agent status for Linux VMs.

The following script can be used to return a concise list of VM names (running Linux OS) and the state of the VM Agent:

```powershell
$vms = Get-AzVM

foreach ($vm in $vms) {
    $agent = $vm | Select -ExpandProperty OSProfile | Select -ExpandProperty Linuxconfiguration | Select ProvisionVMAgent
    Write-Host $vm.Name $agent.ProvisionVMAgent
}
```

 ### Manual Detection
 
 When logged in to a Windows VM, Task Manager can be used to examine running processes. To check for the Azure VM Agent, open Task Manager, click the *Details* tab, and look for a process name **WindowsAzureGuestAgent.exe**. The presence of this process indicates that the VM agent is installed.
