Citrix Health Check

I used and modified the script originally from here.

Note that you need to run the script with elevated permissions (“run with highest privileges” when scheduled or run powershell as administrator when manually running the script).

Script

#==============================================================================================
# Created on: 11.2014 modfied 10.2018 Version: 1.3.7
# Created by: Sacha / sachathomet.ch & Contributers (see changelog at EOF)
# File name: XA-and-XD-HealthCheck.ps1
#
# Description: This script checks a Citrix XenDesktop and/or XenApp 7.x Farm
# It generates a HTML output File which will be sent as Email.
#
# Initial versions tested on XenApp/XenDesktop 7.6 and XenDesktop 5.6 
# Newest version tested on XenApp/XenDesktop 7.11-7.13
#
# Prerequisite: Config file, a XenDesktop Controller with according privileges necessary 
# Config file:  In order for the script to work properly, it needs a configuration file.
#               This has the same name as the script, with extension _Parameters.
#               The script name can't contain any another point, even with a version.
#               Example: Script = "XA and XD HealthCheck.ps1", Config = "XA and XD HealthCheck_Parameters.xml"
#
# Call by : Manual or by Scheduled Task, e.g. once a day
#           !! If you run it as scheduled task you need to add with argument "non interactive"
#           or your user has interactive persmission!
#

	.SYNOPSIS
		Get information about user that set maintenance mode.
 
	.DESCRIPTION
		Over the Citrix XenDesktop or XenApp log database, you can finde the user that
		set the maintenance mode of an worker.
		This is version 1.0.
 
	.PARAMETER AdminAddress
		Specifies the address of the Delivery Controller to which the PowerShell module will connect. This can be provided as a host name or an IP address.
 
	.PARAMETER Credential
		Specifies a user account that has permission to perform this action. The default is the current user.
 
	.EXAMPLE
		Get-CitrixMaintenanceInfo
		Get the informations on an delivery controller with nedded credentials.
 
	.EXAMPLE
		Get-CitrixMaintenanceInfo -AdminAddress server.domain.tld -Credential (Get-Credential)
		Use sever.domain.tld to get the log informations and use credentials.

# Edited on December 15th 2014 by Sebastiaan Brozius (NORISK IT Groep)
# - Added MaintenanceMode-column for XenApp-servers, Fixed some typos, Cleaned up layout
#
# Version 0.7
# Edited on December 15th 2014 by Sebastiaan Brozius (NORISK IT Groep)
# - Added ServerLoad-column for XenApp-servers
# - Added loadIndexError and loadIndexWarning-variables which are used as thresholds for the ServerLoad-column
# - Removed line $machines = Get-BrokerMachine | Where-Object {$_.SessionSupport -eq "SingleSession"} from the XenApp-section (because this is for VDI)
# - Removed Column-positions from comments
#
# Version 0.8
# Edited on January 17th 2015 by Sacha Thomet
# - Added MaintenanceMode-column for Assignments (DeliveryGroups), added MaintenanceMode-column for VDIs
#
# Version 0.9
# Edited on May 5th 2015 by Sacha Thomet
# - Changed some wording terms into account of XenDesktop/XenApp 7.x
# (Assignment to DeliveryGroup, AssignedCount to AssignedToUser, UsedCount to AssignedToDG,
# UnassignedCount to NotToUserAssigned)
# - Added some columns the MachineCatalog (ProvisioningType, AllocationType)
# - Added some columns the DeliveryGroups (PublishedName, DesktopKind)
#
# Version 0.92
# Edited on July 2015 by Sacha Thomet
# - Adjusted some typo
# - Delivery-Group-Section: XenDesktop show Total Desktops assigned to this group (FeatureRequest Luis G)
