i'd suggest RRD (round robin database) - see the rrdtool package. with any
other databases, you have to deal with data accumulation over years of usage.
with RRD, it keeps averages where you get detailed info for the present, and
less detailed but still useful data for anytime in the past (well, for a
reasonable re-definition of 'anytime'). and the file size is always constant.
i have all kinds of performance data for the past 3-4 years yet i don't have
to worry about archiving old data or overflowing or ending up with
garguantian data files.
