RRDtool uses a round-robin-database (as the name tells you), and you can
create more of these being a kind of "interleaved". So you can create one DB
keeping the values per hour of the last month, and another one to keep the
averages or min/max values or so per day of the last year, and maybe even
another one to keep the weekly values over the last 10 years.
I like rrdtool, had it running under NetBSD/vax here a long time to keep
statistics generated by iostat and some scripts around it. So i had the
disk i/o and cpu-load values per second over an hour, per minute over a day,
and per hour over a month or so.
