Hyper-V and PowerShell : VMName to OSName mapping
I have been working on creating a Hyper-V app for Splunk that will allow Splunk users to associate Hypervisor data with products like XenDesktop, XenApp, and Exchange. One of the challenges I came across is mapping the Hypervisor VM name to the OS FQDN.
Thanks to Artem
Function
{
Param(
[Parameter()]
$ComputerName = $Env:ComputerName,
[Parameter()]
$VMName
)
# Creating HASH Table for object creation
$MyObj = @{}
# Getting VM Object
$Vm = Get-WmiObject -Namespace root\virtualization -Query "Select * From Msvm_ComputerSystem Where ElementName=’$VMName’" -ComputerName $ComputerName
# Getting VM Details
$Kvp = Get-WmiObject -Namespace root\virtualization -Query "Associators of {$Vm} Where AssocClass=Msvm_SystemDevice ResultClass=Msvm_KvpExchangeComponent" -ComputerName $ComputerName
# Converting XML to Object
foreach($CimXml in $Kvp.GuestIntrinsicExchangeItems)
{
$XML = [xml+site:msdn.microsoft.com”>XML]$CimXml
if($XML)
{
foreach ($CimProperty in $XML.SelectNodes("/INSTANCE/PROPERTY"))
{
switch -exact ($CimProperty.Name)
{
"Data" { $Value = $CimProperty.VALUE }
"Name" { $Name = $CimProperty.VALUE }
}
}
$MyObj.add($Name,$Value)
}
}
# Outputting Object
New-Object -TypeName PSCustomObject -Property $MyObj
}
Output looks like

PowerShell cmdlets for Splunk!
Project
https://github.com/splunk/splunk-reskit-powershell
Splunk PowerShell Resource Kit
The Splunk PowerShell Resource Kit enables IT administrators to manage their Splunk topology, configure Splunk internals, and engage the Splunk search engine from their PowerShell session.
Example Uses
PS > Get-Splunkd
ComputerName MgmtPort HTTPPort SessionTimeout MinFreeSpace EnableWeb EnableWebSSL Splunk_Home
———— ——– ——– ————– ———— ——— ———— ———–
YETICLIENT 8089 8000 1h 2000 True True C:\Program Files\Splunk
PS > Get-SplunkdUser
ComputerName UserName FullName Email Type DefaultApp Roles
———— ——– ——– —– —- ———- —–
127.0.0.1 admin Administrator changeme@example.com Splunk launcher admin
Here are a few of the tasks enabled by the Resource Kit:
- Determine or change the status of Splunk services across a set of Splunk servers in parallel.
- Force one or more Splunk servers to reload their configuration, in parallel.
- Deploy multiple Splunk forwarders to all active hosts in a Windows domain.
- Retrieve a list of Splunk server classes, optionally filtered by last deployment client connection time, associated applications, or matching patterns.
- Issue a Splunk search and format the retrieved events as a table, a list, or in a windowed grid view.

The 2011 Scripting Games
The 2011 Scripting Games begin on April 4, 2011 and run through April 15, 2011. What is the Scripting Games, you may ask? Well simply put, the Scripting Games are the premier learning event of the year for IT Pro’s and others who wish to master Windows PowerShell. Comprising 10 events, a registered contestant has seven days to create a solution to a scenario driven problem and post their code to a MVP maintained script repository for evaluation by a panel of internationally recognized judges. Daily leaderboards and prize drawings help to maintain the suspense throughout the two-week international event.
During the 2011 Scripting Games hundreds of contestants will submit thousands of scripts that will be reviewed by dozens of judges. Hundreds of thousands of spectators from all around the world will view the games themselves. Last year, participants from more than 100 countries participated in the Scripting Games. With an emphasis on real world scripting scenarios and problems, the scripts will be of immediate value to both the participants and to the spectators.
Preparation for the 2011 Scripting Games is already underway, with a learning guide, step-by-step tutorials, videos and other resources being generated on a daily basis. The 2011 Scripting Games all in one page is the portal for the games themselves. The 2010 Scripting Games all in one page is still available, as are the events from the 2009 Scripting Games.

Its been awhile… what have you been up to?
Sorry I haven’t been blogging much. While I have been very busy at work my Powershell exploits have not been idle 
Here are some updates
- My MVP was renewed
- My CTP was renewed
- BSonPosh module is now in V2 and almost ready to release
- I am speaking at the NYC users group next month (Dec 13th) (powershellgroup.org/nyc)
- Writing a monthly article here (searchwindowsserver.techtarget.com/feature/PowerShell-Scripting-School-20)
- Working on a podcast series for (www.dabcc.com/) *This is going to be a fun one
Anyway… I just wanted to give you a heads up on what was going on with me. Shortly I plan to have a weekly or monthly blog post covering my BSonPosh module which is up to ~140 cmdlets.

BriForum rocked!
As I am sitting here on my way back to NJ from BrForum I am thinking about the week. All I can say is awesome. The content was only matched by the company. People often underestimate the value in conferences and often it is not the actual sessions. In the case of BriForum there is significant value in both. If you have never been to BriForum and you are in the SBC (server based computing) world you are missing out.
p.s. @ShawnBass, @JasonConger, @LauraWhalen, @JimMoyle. You guys rock and I had an absolute blast.
