I have this query that I want to send out an email for anything that is used at a certain percentage. I want to add Free Space as well as % for Used space and then alert on the % of used space that is > 90%. I was hoping to also add a section on the script were certain datastores could be added so they are ignored (ones we know about and don't care ). I also want to have an email sent if there query returns nothing with the subject like - no datastores over 90% usage. Any help is greatly appreciated - I have the gist of what I want but I am not sure how to build in the logic
#poweshell script to query the datastores and send an e-mail for any over 90%
