For reporting purposes, I maintain an Excel sheet containing information on my server base. I update this sheet on a weekly basis. Part of the information displayed in this sheet comes from a PowerShell script run against our vCenter servers. This post is not about the Excel sheet (I will share this with you in a later post), but about the PowerShell code.
A requirement for this script to work is the VMware PowerCLI PowerShell module, which can be installed with this PowerShell command:
1 | Install-Module -Name VMware.PowerCLI -Scope CurrentUser |
See https://blogs.vmware.com/PowerCLI/2018/02/powercli-10.html for more information about VMware PowerCLI.
In order for this script to work for your environment, make sure to adjust variable $vCenterServers to match your vCenter server(s).
Also have a look at variable $VMList. The script below simply gets information about all your virtual machines. For my environment, I limit the number of queried virtual machines, by using a filter. I have left some examples as comments.
