Is there a script that will show memory usage as a graph, for example as a pie-chart, with each process being being a separate slice?
I'm not looking for something like Munin to graph memory usage over time, but rather show the memory usage per-process at a single point in time.
To make my request even more obscure, it is for a headless server (so no X applications). The simplest way would be to write a PNG file, or possibly an HTML file (which could use Javascript to allow the filtering of processes, changing between graph-types and so on)
