Looking for interesting Citrix Problems

I am working on some blog entries and content for Citrix CDN and was curious what you guys thought.

If you have time, please leave some comments on problems or suggestions of things you would like to see. Specifically I am looking for some “real” world scenarios that I can present and provide solutions for.

Get-CitrixFarm (Playing Around Series)

I wanted to show how EASY it is to play with Citrix MFCom so here is a little video.

I also want to note how most of the properties (like Servers,Applications,Zones) all return objects that have their own properties and methods. So you could very easily have these lines in your profile and always have everything just sitting there waiting to be used.

  1. $farm = New-Object -Com ‘MetaframeCOM.MetaFrameFarm’
  2. $farm.Initialize(1)
  3. Write-Host "Loaded Farm Info from $($farm.FarmName)

Citrix License Info (using WMI)

I had several questions about this so I decided I should figure it out and Post. It was surprisingly simple. All I needed was the WMI provider and from there it was cake. If you’re curious how I figured out the WMI namespace I used WMI Explorer from MoW [CLICK HERE To Read about it].

The Output will look like this
Citrix License Script Ouput

Here is the Code

  1. # Get-CitrixLicensing
  2. Param($LicenseServer)
  3. $licensePool = gwmi -class "Citrix_GT_License_Pool" -Namespace "ROOT\CitrixLicensing" -comp $LicenseServer
  4. $licensePool | Select-Object @{n="Product";e={$_.PLD}},
  5.                             @{n="Model";e={"Server"}},  
  6.                             @{n="Type";e={$_.LicenseType}},
  7.                             @{n="Installed";e={$_.Count}},
  8.                             @{n="In Use";e={$_.InUseCount}},
  9.                             @{n="Available";e={$_.PooledAvailable}},
  10.                             @{n="% in use";e={($_.InUseCount/$_.Count)*100}}

Powershell and MFCom (Citrix takes more steps)

Vishal Ganeriwala is hosting a webinar on the 29th of April on Powershell and MFCom. This is just another example of Citrix actively embracing Powershell.

http://community.citrix.com/blogs/citrite/vishalg/2008/04/21/Free+Managing+Citrix+Servers+via+PowerShell+and+MFCOM+webinar

It will cover some basic Powershell for those who do not have much XP with Powershell.
- What is an Object
- Properties
- Methods
- New-Object (-ComObject)

It will also cover how to create a Citrix Farm Object in Powershell and some of the interactive nature of Powershell
- Getting Farm Properties
- Getting Applications
- Getting Servers
- Getting Sessions

Example
- Get Current Sessions Client Resolution

Citrix Script Repo (aka Exchange)

I was recently directed to a new website (for me at least) that contains a repository of Citrix related scripts. There are some pretty useful scripts posted (and I started adding some Powershell ones.) You should check it out

Script Exchange
http://community.citrix.com/display/cdn/Script+Exchange

I would also recommend RSS’ing Vishal blog (Dev at Citrix.) He has a passion for Powershell and I hope to see some awesome things from him in the future.

Get-CitrixApplication.ps1 (Citrix Top 10)

This script returns Citrix Application Objects.
- With no -AppName passed it will return All application Objects
- With -AppName it will return all apps that match (regex.)

  1. # Get-CitrixApplication.ps1
  2. # Brandon Shell [MVP]
  3. # www.bsonposh.com
  4. # Returns Citrix Application Objects for AppName passed or RegEx
  5. Param($AppName=".*",$server=$env:ComputerName)
  6. $type = [system.Type]::GetTypeFromProgID("MetaframeCOM.MetaFrameFarm",$server)
  7. $farm = [system.Activator]::CreateInstance($type)
  8. $farm.Initialize(1)
  9. $farm.Applications | ?{($_.AppName -match $AppName) -or ($_.BrowserName -match $AppName)}

Set-CitrixServerLogon.ps1 (Citrix Top 10)

Here is a useful little script. This Creates a MFCom Server Object and disables or Enables Logons for that Server.

  1. # Set-CitrixServerLogon.ps1
  2. # Brandon Shell [MVP]
  3. # www.bsonposh.com
  4. # Sets the Server to Enable or Disable Logons
  5. Param($Server,[switch]$enable,[switch]$disable,[switch]$help)
  6. function HelpMe{
  7.     Write-Host
  8.     Write-Host " Set-CitrixServerLogon.ps1:" -fore Green
  9.     Write-Host "   Sets the Server to Enable or Disable Logons"
  10.     Write-Host
  11.     Write-Host " Parameters:" -fore Green
  12.     Write-Host "   -Server                  : Optional. Server to Set Logon"
  13.     Write-Host "   -Enable                  : Optional. Checks Hours of Idle Time (Default)"
  14.     Write-Host "   -Disable                 : Optional. Checks Minutes of Idle Time"
  15.     Write-Host "   -Help                    : Optional. Displays This"
  16.     Write-Host
  17.     Write-Host " Examples:" -fore Green
  18.     Write-Host "   To disable the Logon for a Server" -fore White
  19.     Write-Host "     Set-CitrixServerLogon.ps1 -server <serverName> -Disable" -fore Yellow
  20.     Write-Host
  21. }
  22.  
  23. if(!$Server -or $help){helpme;Write-Host;return}
  24.  
  25. Write-Host
  26.  
  27. Write-Host " Getting Server [$Server]"
  28. $mfsrv = New-Object -ComObject MetaFrameCOM.MetaFrameServer
  29.  
  30. Write-Host " - Initializing Server"
  31. $mfsrv.Initialize(6,$Server)
  32.  
  33. if($enable)
  34. {
  35.     Write-Host " - Setting to EnableLogon = 1"
  36.     $mfSrv.WinServerObject.EnableLogon = 1
  37. }
  38. if($disable)
  39. {
  40.     Write-Host " - Setting to EnableLogon = 0"
  41.     $mfSrv.WinServerObject.EnableLogon = 0
  42. }
  43.  
  44. Write-Host " - Server [$($mfSrv.ServerName)] is set to [$($mfSrv.WinServerObject.EnableLogon)] for EnableLogon"
  45.  
  46. Write-Host

Another option would be to remove the Apps from the Server all together.

  1. # Unpublish-CitrixServer.ps1
  2. # Brandon Shell [MVP]
  3. # www.bsonposh.com
  4. # Removes all App from Server
  5. Param($Server)
  6. $mfsrv = New-Object -ComObject MetaFrameCOM.MetaFrameServer
  7. $mfsrv.Initialize(6,$Server.ToUpper())
  8. $mfsrv | foreach{$_.Applications} | foreach{$_.LoadData(1);$_.RemoveServer($Server.ToUpper());$_.SaveData()}
