Vester Test file generator


In previous posts (see below), I presented some tips for creating new Vester Test files. As you may know, ESXi hosts have a large number of so called “Advanced System Settings” Some of these settings are already present as Vester test files. These Advanced System Settings can be handled with the Get-AdvancedSetting and Set-AdvancedSetting cmdlets. With this knowledge and some PowerShell code, it is not to difficult to create a complete set (>1.100) of Vester Test files.

The New-VesterHostAdvanced.ps1 script can be found here.

A brief description how it works. After connecting to a vCenter Server, one of the available ESXi hosts needs to be selected. The selected host will be used to create an overview of all available Advanced System Settings.

Key in creating the scripts is the concept of Here documents, in PowerShell known as Here-String. See for a brief overview. Key in Here-Strings is the usage of single or double quotes with variables. A Here-String with double quotes allows the usage of variables. Run the following code to see the difference.

$var = 'MyValue'
$formatText1 = @"
Here-String with double quotes
The variable $var
Variable replacement


$formatText2 = @'
Here-String with single quotes
The variable $var
Test as-is
