In order to know the XenApp farm, we implemented a powershell script (XenApp_Check.ps1) , this will provide information to get a precise idea of the current state.

XenApp_Check generated an HTML file, and send a report by mail (htlm), to be able to be informed  wherever you are.

XenApp_Check (same as XenApp_InfoFarm) is inspired from the graph part of vcheck from the Vmware community.

XenApp_Check will bring a serie of information to give  a summary fo the XenApp farm , along with a serie of check outputs (detailed below in this post), this provides an instant status of the XenApp farm (very convenient in the morning, when the ‘admins’ arrive for instance, or if you have to work on an XenApp farm that you have never monitored previously 🙂 ).

XenApp_Check was tested on windows 2003 server Fr sp2 and Xen App5 fr with R01,R03 and R06, XenApp_CheckXA6 ​​has been tested on servers 2008 R2 sp1 and XenApp 6 R01 Farms.

Information part :

  • Farm name
  • Datastore type
  • Datastore server
  • Licence server name and port
  • Number of servers
  • Number of applications
  • Number of zones
  • Number of load evaluator
  • Number of administrators

Check part :

  • Dschek
  • Disable policy
  • Test presence of the event 4033 on the members servers of the XenApp farm (in order to be able to visualise the elections of the ZDC
  • Test the principals servers XenApp (the service spooler as well) on the members servers of the farm XenApp
  • Test the disk space remaining on the servers member of the XenApp farm ( if the space disk is below 1.7 Go, we consider it as an alert to escalate)
  • Test if the open session on the members of the server is not disable
  • Test if the member servers of the farm XenApp belong to a specific Load evaluator ( in our case the Load evaluator is named “maintenance” and allow to exit a server from our production via  the scheduled task).
  • Test if one application has at least two servers to be pusblished
  • Test if one application is disable


Prerequire XenApp_Check :

  • Powershell V2
  • Citrix XenApp Command CTP3
  • Modify the row 24 in the file XenApp_Check.ps1  in order to indicate the place where the file Ctx_Functions.ps1 is located
  • Modify the rows 27,29 et 31 in the file XenApp_Check.ps1 for the part email send  Configure « # Set the SMTP Server address”  in XenApp_Check.ps1  file to send email
  • Modify the rows 41 et 43 in the file  XenApp_Check.ps1 to precise where the html and their back up will be save/archive.

The execution of XenApp_Check on a farm of  304 servers, 484 applications, 6 zones, 10 Load Evaluators and 10 Policies takes around 45 mn 30 mn.

Any suggestions and feedback will be welcome 😉 .
