It’s been a couple of weeks since I’ve touched my Documenting with PowerShell series. I figured to get it started again we get going with Hyper-v. I use Hyper-v for nearly all our virtualized deployments. This script documents the following items:
- The current Virtual Machines
- The Virtual Machine network settings
- The host network settings
- The host settings
- and the Virtual Replication settings
So this script has both been tested on a larger hyper-v cluster and a local hyper-v machine. We use this information if we ever need to do a rebuild or just check how the system is setup.
As always I’ve made two versions. One for IT-Glue, and one that generates a HTML file.
IT-Glue version
The IT-Glue version of the script uploads a new Flexible asset if it does not exist, and fills the data for you. If you don’t feel confident with leaving your API key in a script because your RMM cannot handle credentials that well, please check out this blog I wrote about the IT-Glue API.
