1 year back I had written this script, and it became very much popular, Collect disk space detail and send it in email Powercli since then I started receiving emails for some more additions in the existing script. I am not a HTML guy but still tried to create one, Many of the people found they don't have to login each server to collect disk information, They just need to login vCenter (Powercli) which saves lots of time. Also to work this script correctly make sure all your VMs has VMWare Tools installed and running. Also my earlier script was pulling reports only for Windows and C drive.
I have improvised it little bit and added below information.
This is the screenshot how collected information will looks like in the email.
Once you execute script you will see below results on the screen which can tell you from what vm and disk it is collecting information. I am running this one Windows server 2012 R2, Powercli version 5.5, vsphere 5.5.
Below is the code information

I have improvised it little bit and added below information.
- Information for all vmware vm disk usage,
- Any disk has below 20% will be in Red.
This is the screenshot how collected information will looks like in the email.

below step you can do earlier as well when you finished coping file, but I prefer in the last what if copied file is corrupted. Remove-PSDrive vDATA will unmap mapped datastore drive.
