PowerManagement for dedicated Citrix desktops? Yes with Tags!

Are you using Tags in your XenApp & XenDesktop environment? Maybe you should. Tags to resources, in my case desktops can be very powerful especially in combination with PoSh scripts. You can do actions for machines depending on the tag. Of course you also can use tags to filter Citrix policies on it, also useful.

I had the Problem that I have a delivery group with dedicated Win10 desktops so for dedicated desktops there is no power management. Usually it’s also not needed because if a user launch a Citrix Session over Storefront the machine get’s powered on. The problem in my case, sometimes users connects on an other ways than Citrix to his desktop, so this built-it construct doesn’t work. So if they shutdown their virtual Desktop they can newer ever access it until an admin power it on over director or studio.

My solution to this was, I tagged this special user machines with a tag “AlwaysOnline” in Studio and I wrote this small script which runs every 15 minutes:

param([string]$tags=$(throw "Tag parameter is required"), [string]$poweroperation=$(throw "Power operaton parameter is required"))
#==============================================================================================

# File name: PowerOperation-DependingMachineTags.ps1
#
# Description:  This is a Powershell to change the PowerState of VDI's or XenApp Servers in
#               a PowerManaged XenDesktop 7.x environment accodring to Tags.

if ((Get-PSSnapin "Citrix.Broker.Admin.*" -EA silentlycontinue) -eq $null) {
try { Add-PSSnapin Citrix.Broker.Admin.* -ErrorAction Stop }
catch { write-error "Error Get-PSSnapin Citrix.Broker.Admin.* Powershell snapin"; Return }
}
# Change the below variables to suit your environment
#==============================================================================================



$maxmachines = "1000" # as default only 250 records, this increase it to 1000
#$tags = "AlwaysOnline" # if you comment out the param line you can have the tag here
#$poweroperation = "TurnOn"  # if you comment out the param line you can have the poweroperation here



$machines = Get-BrokerMachine -MaxRecordCount $maxmachines | Where-Object {$_.tags -eq $tags }



foreach($machine in $machines)
{
$machinename = $machine | %{ $_.MachineName }
Write-Host "Action $poweroperation will be performed for $machinename  "
New-BrokerHostingPowerAction  -Action $poweroperation -MachineName $machinename
}

I know I know, this is not a common use case, but the script construct show what is possible with tags … there are almost unlimited possibility to cover special cases with tags.

My example Script on GitHub: PowerOperation-DependingMachineTags.ps1

Finally 1.0 – but never finalized!

In November 2014 I created the blog post about the adaption of the PVS Script for XenApp/XenDesktop 7.x :
XenDesktop & XenApp FMA (7.x) HealthCheck – Oops!… I Did It Again

sheepsNow after almost two years of continuous development on this Script, the XenApp & XenDesktop 7.x Health Check has now Version 1.0.

I started this script in a very basic version and in the meanwhile lot of tester and contributors helped to bring this script in this version. Just this year I started with GitHub and it’s surprising, the community who helped is awesome!

Now after a number of 0.x versions, just at the point we introduce the XML configuration file, I can say the version now has deserved the number 1.00.

xaxd-xml

The big benefit of the configuration in the XML file is in case you have multiple environments with the script you don’t need to edit the header section of the script which has earlier contained the config. On a new version of the script, you just replace the script in your environments and keep the XML file.

The XML file and the script need to be in the same directory and the Name of the XML file need to be same like the script, e.g:

XA-and-XD-HealthCheck.ps1
XA-and-XD-HealthCheck_Parameters.xml

The XML-Config is introduced to this script by Stefan Beckmann (Twitter: @alphasteff)

github

The newest version of the script you can find on GitHub:
https://github.com/sacha81/XA-and-XD-HealthCheck 

html script output

The HTML Output file gained some more input, even it was difficult to decide which feature request to consider and which not.

We check now CPU, Memory and disk space of controllers and workers (XenApp Server and XenDesktop VDIs). Because I learned last month’s that with 7.x and the FMA architecture it’s really possible that an environment contains number of different VDA versions, I also added this info. And for troubleshooting reason I assumed that it would be helpful to have also the hypervisor host information on this output.

The code is on GitHub:

victim of a good reputation – Low free pooled XenDesktops

The Citrix Director is not so bad, and with Version 7.7 it is still better because now it’s possible to send email alerts. But one problem I still have … our provided pooled XenDesktop which are used for remote access with private computers are victim of a good reputation … this means a good word-of-mouth advertising in our company more and more people are tempted to use it … and we need to know when the number of free pooled desktop is low. And no I won’t go the read the numbers every day in director or Citrix Studio.

So I created a small script which send me an email as soon a defined threshold of free desktops is reached:

low-free-desktop

Happy New Script – PVS 7.7 HealthCheck

We are close to the New Year 2016 and I want to wish you all the best for 2016!
I’m already happy now, because I can publish some hours after the PVS 7.7 release from Citrix this Script:

Today Citrix released XenApp/XenDesktop 7.7 and Citrix Provisioning Services 7.7. There are a bunch of new features, but for me the most important thing, beside of the Win10 support, is
….  drum roll ….
the new PVS PowerShell API. PoSh with PVS 7.6 and below was a pain …  To know what else is new in PVS look here: PVS 7.7 New in this release

Now PVS comes with a real PoSh interface which gave more back than a bundle of strings. I had the chance to play around with PVS 7.7 Tech Preview and so here you have already the PVS HealthCheck Script for Version 7.7 in a complete new developed version:

pvs77

If you have a feature request or a bug report please post it direct on GitHub.

This version doesn’t work with PVS 7.6 and below, if you have an older version than 7.7 take this script: Citrix PVS HealthCheck 

Update 11.04.2016: Performance-Improvement, Change the order of the table, all the VDI status now at the end.
Update 09.05.2016: Bugfix & Input from Jay, get CPU/Memory/Disk usage of PVS.
Update 27.05.2016: Now my Script is on GitHub
I’m an absolute GitHub newbie … for this reason I leave it still also here as a download until I’m really comfortable with GitHub.

The code is on GitHub:

Monitor you Profile directories

Since I had worked as a Citrix administrator the size of the profile directories was always a contemporary issue. It’s a fact that with new technologies like Citrix User Profile Manager the possibilities are grown and the life is easier with exclusion lists and profile streaming features. But it’s still a topic to consider if you are a Citrix admin or system engineer. I worked in former company with tools like TreeSize (https://www.jam-software.com/treesize/) or WinDir Stat (http://windirstat.info). But in some company they wont to spend money for tools which is only usable for one administrator or they don’t trust to OpenSource software (TreeSize).

I have the approach to solve every possible problem with on-board tools. So I created now a small script what give me the possibility to check my Profile directory with one recursive level so that I get each Size of a Profile within his subdirectories.:

PoSh Script who alert me if I’m running out of pooled Desktops

Just a small one, last days I’ve created a small script who alert me if I’m running out of pooled Desktops.

If you run this script at regular intervals you will receive an email as soon you have less desktops free than you defined as threshold:

GeekOvation – PVS Script on Top3

geek-zone-150x150My Citrix PVS Health Check PowerShell Script was nominated into the final round (Top3) of the Citrix GeekOvation Award. This means I have to present my “geeky solution” on Citrix Synergy 2015 in Orlando on the SYN501 Geek Speak Tonight Session. To be honest to speak in front of so much people is a new thing for me … and it makes me “a bit” twitchy …

To be nominated for this Award was not just a big surprise for me, I see this also as a honor and glory for my work. I would say it’s not so a big thing this script and it isn’t rocket science.

Dear GeekSpeak Tonight audience, please check out my PVS Health Check Script and provide me feedback if you want. Also have a look to my XenApp / XenDesktop Script

At this place  I want to say thank you to Jason Poyner who gave me the idea for such kind of Script with his XenApp6 HealthCheck and where I took some code lines for the HTML output. To Martin Hartmann who helped me by learning PowerShell and of course to Aaron Parker (http://stealthpuppy.com) who was  the assigned CTP helping me polish off my presentation materials.

Update 14.5.2015:

I won – thank YOU

geekovationI won the competition and seems that I’m the not-yet-known Geek #1 this Year! Thanks you all! When I saw the work from to other two guys, I had the feeling to have no chance, not just because I’m the only not-native english speaker. David Ott with a great PowerShell script to modify the user profile and Shane O’Neil with the C-Sharp code to have a self healing VDI, GREAT!

Read this blog post from Shane and Paul, if you are interested on more PVS PowerShell stuff: http://blogs.citrix.com/2015/04/07/wait-you-mean-pvs-has-powershell and watch the recording of “SYN514: Turn XenApp and XenDesktop into capacity on demand with Provisioning Services automation”

I’m sure I also had luck to win, and now I have the chance to go to Las Vegas Citrix Synergy 2016. I also want to thank ControlUp for the AppleWatch they sponsored for the GeekOvation Winner.

About the code

Like already mentioned the idea about the health check with the HTML output comes from Jason Poyner. The main script with all the logics it’s from me. The hardest thing when you Script with PoSh on PVS that it doesn’t return proper PS Object, that mean’s you doing a lot of format-cut stuff to get what you want. If you want to know more about that read Paul’s blog section “PVS comes with a PowerShell add-in that is not an easy beast to tame.

What’s next?

I’m currently working on a Script which shows PVS retries during a variable timeframe (day, week or month) and create a graphic output, in this way you can see at which time you maybe have a traffic jam on your network.

I also made a script to export/import target’s into PVS and another one for export and import in XenDesktop, if I have time I’ll polish and publish this here.

XenDesktop & XenApp FMA (7.x) HealthCheck – Oops!… I Did It Again

Some months ago I’ve created the Citrix PVS Health-Check Script which is a based on the idea and some parts of code from the Health-Check Script for XenApp 6.x of Jason Poyer (http://deptive.co.nz/) .
Because now XenApp 7 with the Release 7.6 is finally in a state where considering an upgrade of the 6.x farms make sense, I belief that the demand for a XenApp 7.x Health Check Script grows.

So I did it again and took the “HealthCheck framework” to build a new version which combines the Power of the Citrix PS-Snappins for XenDesktop/XenApp and  the HTML-Output-Script of the existing HealthCheck Scripts.

The result is a new HealthCheck Script which is usable for XenApp and XenDesktop 7.x and what makes me also happy, with only a few line of more code the Script is downwardly compatible for XenDesktop 5.6 environments.

  XenDesktop XenApp Health Check HTML Output

This is just the first version and I’m sure that more check’s need to be added. Feedback and “Feature requests” are welcome … And to be honest I have not yet a big environment to test my Script, so please be insightfully if you find some bugs and report them to me.

In the first part of the Script you are able to configure some parameters. You can decide if you only want to see the “bad” Desktops on which something it’s going wrong or if you want see everything. In huge XenDesktop environments you want definitely only see the bad machines …  ( $ShowOnlyErrorVDI = 1 ) Also you can decide if you want only report XenApp or only XenDesktop or both. The Desktops and XenApps are in two different Tables. It’s also possible to exclude Collections ($ExcludeCatalogs) from the Check, so virtual Desktops which are for testing purposes are not checked.

If you have a feature request or a bug report please post it direct on GitHub.

Update 12.05.2016 (Version 0.95):
– Check CPU, Memory and C: of Controllers
– XenApp: Add values: CPU & Memory and Disk Usage
– XenApp: Option to toggle on/off to show Connected Users
– XenApp: DesktopFree set to N/A because not relevant
If you need a Health Check Script for XenApp Version which are older than XenApp 7.x see http://deptive.co.nz/xenapp-farm-health-check-v2 where it’s an excellent work and the inspiration for my HealthCheck-Scripts!

Citrix PVS HealthCheck

Problem: There is currently no free tool to check the health status of a Citrix Provisioning Services farm with all Citrix relevant parameters. There are monitoring tools which tell you if a server is up and running or if it’s not, but now tool who gives you a special overview for Citrix Provisioning Services according to how much targets on which server, how much communication retries on which target an so on.

Solution:
Since some year’s I’m using the XenApp Health Check from Jason Poyner (deptive.co.nz) to get daily a status of my environment(s). I really appreciate the work from Jason, if you don’t know it until now, you really need have a look on his blog and on the Script . The mentioned XenApp Farm Health Check Script gave me the inspiration to create a similar Health Check Script for my Citrix Provisioning Server farm. To be honest, and I’m happy that Jason doesn’t mind, that I have “recycled” some parts, or say the “framework” of his XenApp Farm Health Check script to build my Script.

The script I built can be scheduled with a Windows task which trigger a run once a day and send out a email with the attached HTML-Report:

I’ve written the Script to perform the checks in 3 Parts: 

Target Devices:

  • Ping
  • Retry (Threshold configurable, default is 15)
  • PVS Disk (Value which I read from PVS farm with get-mcli)
  • PVS Disk (Value which is written in the personality.ini on the Target)
  • PVS disk version (V1.2)
  • The vDisk-Store *
  • PVS Server
  • WriteCache Size

* like you can read in my BlogPost “Achieve fastest Citrix Provisioning Target Device” I propose to have the vDisk Store local on each provisioning server. So I can check with that column if the Target is booting from the correct vDisk store. The Master Store is on CIFS and only used for updates of the Image.

vDisks:

  • Replication state (PVS don’t replicate anything – but can check if the vDisks on all servers are equal)
  • DeviceCount to see how many targets are currently reading from this Image
  • Load Balancing algorithm
    (Green if Best Effort because I want to have subnet affinity – feel free to change for your need.  I have two data centers with two separated subnet’s – so I can guarantee that each target stream from his own data centre as long the server is available. Just in case of an outage of all PVS server in one DC it fail over to the other DC  )
  • WriteCache Type
  • Name & Date of the vDisk

PVS Servers:

  • Ping
  • Active
  • How many device are connected

Don’t forget to register the PVS SnapIn DLL e.g. with .Net Framework 2.0 with the command:

“C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe” “C:\Program Files\Citrix\Provisioning Services Console\McliPSSnapIn.dll”

Otherwise you get a blank output. If you have another .Net Framework version or path, please adjust the path in the command!

Question or suggestion for improvement? Just contact me.

Update 12.11.14: Now in version 1.2 it’s possible to define the device collection which should be checked. An other additional feature is that the script shows the version of the vDisk.
Update 15.08.15: Now in version 1.4 it’s possible to have more than just one vDisk store.
Update 16.09.15: Now in version 1.5 the vDisk file name, it’s date and the count of the used disk will be showed.
Update 14.10.15: Version 1.61 New feature, PVS Cache (on disk or Ram) will be reported. / 20.10.2015 1.62: fixed some bugs (see comments)

Update 29.12.15: If you use PVS 7.7 or higher check out the new blog post with the 7.7 Script: http://blog.sachathomet.ch/happy-new-script-pvs-7-7-healthcheck/

Because of the Release of PVS with the new PoSh API the further development of this Script is discontinued. Sorry.

Create published applications XenApp to each server

For testing purposes it can be helpful to have a published application without loadbalancing to every single server of your Citrix Farm. The creation of such application can be easily done with the following example script which create a CMD on every farm server:


Add-PSSnapin Citrix.XenApp.Commands -ErrorAction SilentlyContinue
$serverlist = Get-XAServer #Get all server from farm

#Mainprogram
# loop through all servers

 foreach($srv in $serverlist)
 {

 echo $srv.ServerName

 New-XAApplication -BrowserName "cmd on $srv" -ApplicationType "ServerInstalled" -DisplayName "cmd on $srv" -FolderPath "Applications/Published Apps/z_admin" -ClientFolder "Administration\cmd" -Enabled $true -CommandLineExecutable "C:\Windows\system32\cmd.exe" -WorkingDirectory "C:\Windows\system32" -AnonymousConnectionsAllowed $false -AddToClientStartMenu $false -InstanceLimit "-1" #-WindowType "1024×768" -ColorDepth "Colors256"

 Add-XAApplicationAccount -BrowserName "cmd on $srv" -Accounts "domain\USER1"
 Add-XAApplicationAccount -BrowserName "cmd on $srv" -Accounts "domain\USER2"
 Add-XAApplicationServer -BrowserName "cmd on $srv" -ServerNames $srv.ServerName

 }


By the way … if you made a mistake you can remove the created applications by the same foreach-loop with Remove-XAApplication:

 

$serverlist = Get-XAServer #Get all server from farm
#Mainprogram
# loop through all servers
foreach($srv in $serverlist)
 {
 
 echo $srv.ServerName
 Remove-XAApplication -BrowserName "cmd on $srv"
}
