Has anyone devised a decent way of trending disk space usage? Some goals would be:
1. When will I get below X free space (where you fill in X)? Or at least when will I run out of space?
2. When will I get below X % free space (where you fill in X)?
3. Given X date, how much space will I have free then?
All of these would be based on a given time frame that we choose (or at a minimum SW presets). So If I chose start date X and end date Y, based on those trends we'll get #'s 1, 2, and 3 above.
I have to give reports on this type of data and I don't see a good way to do this with SW. However I know our SAN vendor has this built into their software so I'm sure it's more of a calculation thing.
Maybe even a SQL query that takes the differences in disk space over a given period and calculates average change per day and then multiplies that out until at x space free or a given day?
