This script was put together with various snippets I have found online as well as custom code to query your production Central Management Server.
The script works through the CMS and gathers server information, including, disk allocation, OS Versions and patch levels, memory allocation and SQL Server edition information.
I put this together as I am constantly asked by management to give them a report on what is being used and what SQL Servers resources are allocated to a specific environment, and the business I work for, we have hundreds of SQL Servers in various environments, so I decided to work efficiently and provide this information faster and efficiently.
