vCheck is a PowerShell HTML framework script that started with one guy, but is now a community driven and from what I have seen, it’s pretty neat.

vCheck can be configured to just run once, or as a scheduled task on a Windows box. It also offers the option of sending the report via email. With those two features coupled together, you can set up a daily environment scan to run an hour or two before you get to work each morning and have a nice HTML report in your inbox of what changed and/or broke since you left the night before.This tutorial covers the installation and configuration of the vCheck tool.

Programs Needed:

• PowerCLI – Latest Version is best but will work with 5.0+
• PowerShell – minimum Version 3
• vCheck – (Download the zip and extract)
  • vCheck Dev Version (use at your own risk)

Download and Extract vCheck with Powershell:

$ZipPath = "C:\vCheck\vCheck-vSphere-master.zip"
$Destination = "C:\vCheck\"

IF (-not (Test-Path -Path "$Destination"))
{
    New-Item -Path $Destination -ItemType Directory -ErrorAction SilentlyContinue
}

iwr https://github.com/alanrenouf/vCheck-vSphere/archive/master.zip -OutFile "$ZipPath"
Add-Type -assembly "system.io.compression.filesystem"
[io.compression.zipfile]::ExtractToDirectory($ZipPath, $Destination)

Load PowerCLI (open the Program)
Login to vCenter Server

Connect-VIServer

– or –

Connect-VIServer VCENTER.DOMAIN.COM -User DOMAIN\Administrator -Password -SaveCredentials

Run vCheck ps1 file

& "C:\vCheck\vCheck-vSphere-master\vCheck.ps1"

- or - 

. "C:\vCheck\vCheck-vSphere-master\vCheck.ps1"
