The ability was added for the MySQL usage to be calculated in the disk space usage, what can I do about making it use the info? What I mean is I just found a customer on a shared server with a 5 gig plus database, I know that if the disk space goes over OR the bandwidth goes over it suspends the account. So since MySQL is added to the disk space, why didn't this account suspend.... months ago?

MySql usage added to total usage... but doesn't trigger anything-mysqlusage.png
