Where has my disk space gone? Flame graphs for file systems
A flame graph does not feel like the best visualization for this kind of data. You can't really make anything of the top spikes and there is a lot of blank space that is wasted. I prefer tree maps as they make more efficient use of the available screen space.My favorite tool for this is SpaceMonger v1.4.0 (http://www.aplusfreeware.com/categories/LFWV/SpaceMonger.htm...), which has a very neat layout algorithm. It's a Windows app but it works OK using Wine with only a few minor graphic glitches.
