ObserveIT

This is the unofficial ObserveIT PowerShell module developed by ObserveIT Professional Services.
It currently allows you to install and uninstall ObserveIT, as well as perform several other operations.
To get help on how to use each function, use Get-Help <function name>.
Please note: this module currently correctly runs on PowerShell 5.0 and higher, and may not run correctly on previous PowerShell versions or on Windows Server machines older than 2016.

Version history:
Version 0.7.5 2018-05-10 13:20:58
   The script now retries the installation of a component if the installation fails.
Version 0.7.4 2018-05-08 20:55:20
   Prevent the script from removing the IIS settings for ObserveIT. This just makes a mess.
Version 0.7.3 2018-05-03 13:50:11
   Various minor fixes and improvements:
   The Set-OITEncrypt and Set-OITDebug functions no longer change the encryption state of the Notification Service due to an apparent bug in the configuration file. You will have to alter it manually.
   The script now backs up the current configuration file prior to performing the change. The backed up file is stored in the same directory.
Version 0.7.2 2018-05-02 12:17:08
   After running Install-OIT, the function displays a list of currently installed products. Used to validate that the expected products were indeed installed.
Version 0.7.1 2018-05-02 11:56:42
   The Install-OIT function now checks whether we're installing ObserveIT version 7.5 or higher. If we do, it installs the NodeJS prerequisite.
Version 0.7.0 2018-05-01 15:38:12
   Added the Get-OITFreeSpace function. This function tests specified drive on the server for free space. Either monitor space left in GB or percentage.
Version 0.6.9 2018-04-26 15:29:20
   The Web Console installation procedure now installs the Node.JS prerequisites.
   During removal, the script now cleans up the folders it can and removes IIS settings.
   During installation, the script configures IIS. You can also specify a custom port for the Application Server and Web Console during the installation.
Version 0.6.6 y2018m04d24h15m41s41
   Updated the Install-OIT function for easier setting of GUI level for the installer. Instead of specifying the level via the actual MSIEXEC switch, you can
   specify it via the function's own switch.
Version 0.6.5 y2018m04d17h17m38s06
   Apparently, previous fix did not resolve the issue with Web Categorization module services not stopping. This should work now.
Version 0.6.4 y2018m04d17h14m20s23
   Resolved an issue where Web Categorization module services would not be stopped prior to removal.
