Inventory reports are a communal petition erstwhile administering a VMware vCenter environment. Learn however this VMware PowerShell publication tin marque specified requests speedy and easy.

As idiosyncratic who administers a VMware virtual situation and has been done respective institution mergers, moving inventory audits is 2nd quality to me. It's ever a bully thought to support a existent inventory of your virtual machines successful bid to champion negociate the environment, but owed to the ever-changing quality of technology, wherever systems are built oregon decommissioned astatine a regular pace, it tin beryllium similar trying to deed a moving target.

Prerequisites

Use Windows 10 (it's theoretically imaginable to tally this successful Windows 7, but you whitethorn acquisition headaches with outdated PowerShell versions since this publication requires PowerShell 4.0 astatine minimum).

Run Windows PowerShell ISE arsenic Administrator (you tin besides usage regular PowerShell, but I find ISE champion for maximum results arsenic good arsenic mistake evaluation).

Install the VMware PowerCLI module utilizing this remark wrong the PowerShell ISE Window:

Install-Module -Name VMware.PowerCLI

If you get an mistake that you request NuGet supplier mentation 2.8.201 conscionable click Yes and the process volition download and instal it for you. It volition instrumentality a fewer moments and you'll past request to click Yes to proceed, and successful a fewer much moments you volition spot the programme installing the related VMWare.PowerCLI packages.

SEE: Microsoft PowerShell: Learn however to automate your workday (TechRepublic Academy)

Since the publication requires the VMware.VimAutomation.Core module besides marque definite it's the latest mentation (as of October 2021) installed via this command:

Install-Module -Name VMware.VimAutomation.Core -RequiredVersion 10.0.0.7893909

Click Yes to proceed and successful a fewer much moments you volition spot the programme installing the related VMWare package.

If you person an mistake stating: "PackageManagement\Install-Package : Authenticode issuer 'CN=VeriSign Class 3 Public Primary Certification Authority - G5, OU="(c) 2006 VeriSign, Inc. - For authorized usage only", OU=VeriSign Trust Network, O="VeriSign, Inc.", C=US' of the caller module 'VMware.VimAutomation.Core' with mentation '10.0.0.7893909' is not matching with the authenticode issuer 'CN=DigiCert Trusted Root G4, OU=www.digicert.com, O=DigiCert Inc, C=US' of the previously-installed module 'VMware.VimAutomation.Core' with mentation '12.4.0.18627056'. If you inactive privation to instal oregon update, use-SkipPublisherCheck parameter"

run this command:

Install-Module -Name VMware.VimAutomation.Core -RequiredVersion 10.0.0.7893909 -SkipPublisherCheck

You tin besides spell present and download the latest mentation to ("C:\Program Files (x86)\VMWare\Infrastructure\PowerCLI\Modules"):

Customizing the script

The publication relies connected these variables (Figure A):

$vcs = @("vCenterFQDN") # FQDN of your vCenter server.
$logFile = "C:\Temp\VMInventory.csv" # Where you privation to prevention the CSV record
$vcsCluster = "*" # Filters which clump you privation to propulsion VM stats from
$businessUnitName = "Element" # Name of concern portion that the publication is gathering stats for

Figure A

For $vcs, you tin regenerate @("vCenterFQDN") with the sanction of your vCenter server successful quotes; different the publication volition punctual you to participate the name.

For $logFile, the logfile way and sanction tin beryllium changed accordingly.

For $vcsCluster you tin specify the clump to stitchery information from, oregon permission this enactment arsenic is to propulsion accusation from each clusters.

For $businessUnitName, regenerate the illustration "Element" introduction with your concern unit, section oregon group.

Running the script

Click File past Open and browse to wherever you saved the publication record to prime it past load it into PowerShell ISE. Hit the greenish fastener to execute it.

If you get an mistake related to information policies oregon the publication being unsigned, tally this bid to let section scripts and distant signed scripts:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

If you near the $vcs adaptable arsenic is you volition beryllium prompted to participate the vCenter server sanction (Figure B).

Once you participate the sanction you'll beryllium prompted to authenticate to vCenterj (Figure C). Make definite to usage an relationship with administrator-level credentials.

Figure C

You volition past spot the publication moving and actively gathering information (Figure D).

Figure D

The publication volition show the results, arsenic good arsenic prevention the details to "C:\Temp\VMInventory.csv" if you near the related adaptable arsenic is (Figure E).

(Note I person removed the FQDN entries that were listed since this was tally against an progressive concern environment.)

Thank you, Brad, for an fantabulous instrumentality each VMware head should person successful their toolkit!
