rrdtool?

[Grig Gheorghiu]

I don't know of any, so maybe it's time to roll our sleeves :-)

Actually, a while ago I started a python project called perfstats
(<http://sourceforge.net/projects/perfstats>) which uses SNMP to
retrieve various system performance metrics, stores them into a
Firebird database, then displays them using the biggles module. I
haven't worked on it in a while, and I'd rewrite it from scratch
probably. If you want to see the source, check out
<http://cvs.sourceforge.net/viewcvs.py/perfstats/>.
