I am trying to figure out if there is any way to find out total storage consumed in a Azure subscription, either via PowerShell or may be OMS. Any help will be appreciated. Thanks in advance.
I haven't tried it myself but from reading the article you should be able to use some of his Powershell code. http://www.azurefieldnotes.com/2017/03/12/how-to-calculate-azure-vhds-used-space/
