There is a tile in the Report section called "Log Space Used %". Having a tile for mdf files, ie "Data Disk Space Used %", would be very handy in setting initial sizes in the first instance and would also give you a heads up in setting file sizes appropriately going forward.
All this would then be sent via email on a daily basis to monitor both log and disk sizes - so that unexpected file growth is one less thing for a DBA to worry about.
I understand there is something similar in the Estate section, but this has no way of emailing the results through automatically to anyone on a regular basis for continuous monitoring (as far as I can see).
Thanks.
