[rrd-users] Big rrd files (too big !)

[Vial, Sylvain]

Hello,
 
I'm actually working on a perl script to provide the top ten for source
ip addresses and destination ports for the tcp/udp protocols.
I use the netflow tools (flow-cat, flow-report) to generate top ten and
I've created rrd files to generate graph as you can find on the honeynet
brazilian project 
(http://www.honeypots-alliance.org.br/stats/flows/tcp-udp/).
My problem is that I generate rrd for each ip address and each port I
detect in my ft files (flow capture).
Each file takes 3MB of hard disk space, so it takes finally a huge space
on my pc.
I'm like a rookie with rrdtool and perl, so if someone could explain me
why it takes so much space and if it exits a better way to realize the
same thing as brazilian.br, it will be great.
Thanks for your help.
