Are there any common Linux tools that track disk space over time, not just a filesystem overall, but for example, so I could easily see which directory trees swelled up and shrunk historically? The problem happens on servers which seem to keep hitting 0 free space despite routine house-cleaning of cache and tmp files, logs etc. I already use tools like
lsof often and schedule
at jobs to find aged files over a certain size/type when low water-marks are hit, etc.
Preferably a Debian/Ubuntu package.
