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!

# Created on: 08.2014            Version: 1.63
# Created by: Sacha Thomet, blog.sachathomet.ch / sachathomet.ch
# Filename: Citrix-PVS-Farm-Health-toHTML.ps1
#
# Special Thanks to:
# - Jason Poyner ... I've borrowed parts of the script and ideas to create this 
#   PVS health check script. Check his excellent XenApp Health Check @ techblog.deptive.co.nz.
# - Martin Hartmann to share his PowerShell KnowHow with me.
#
# Description: This script checks Citrix Provisioning Server, Farm, vDisk & Target devices.
#
# Prerequisite: Script must run on a PVS server, where MCLI snap-in is registered.
# Register SnapIn with command: C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe 
# "C:\Program Files\Citrix\Provisioning Services Console\McliPSSnapIn.dll"
#
# Call by : Scheduled Task, e.g. once a day
#
# Change Log: 
#      V1.1:  Consolidated code
#      V1.2:  Add possibility to check only specified Versions
#      V1.3:  New version after Citrix Synergy 2015 GeekOvation Award nomination. 
#		      With correction of typos and add some documentation lines. 
#      V1.4:  Possibility for multiple stores (Thanks to Kafedzhiev  for the code) (08-2015) 
#      V1.5:  Show create date of vDisk, FileName and the count of the used vDisk (09-2015)
#      V1.6:  Add RamCache used from each target, added code by Jonathan Pitre, 
#		      code from Matthew Nics http://mattnics.com/?p=414 (10-2015) 
#      V1.61: Changed RamCache to general WriteCache, add possibility to get Size of Cache on HD
#      V1.62: Correction in Header to show correct farm name instead a "6", correction in 
#		      LoadBalancingAlgorithm, Error if a disk is assigned fix to a server. 
#      V1.63: Check of Stream-, Soap-, and TFTP-Service (12-2015)

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.
