CONTEXT: We have some databases with multiple filegroups, I’d be useful to be able to drill down from the DB level to the FG level on the “Total data file size” and “Total data file used” metrics.

PROBLEM: Not being able to slice totals by FG is problematic, since different FGs often have different capacity / performance requirements, different space used speed/patterns etc.

EXAMPLE SOLUTION: For “Total data file size” and “Total data file used” add an additional selector window after the database selector: a list of filegroups + an (All) option at the top. So, the selectors would be: machine->instance->DB->FG
