to expand on this, I'd probably write a perl or python script that ran
the iptables -vnL command, and parses the output, and store the values
in a file or sql database along with a timestamp. If all your iptables
sampling rules are in the INPUT table, you can restrict the output with
`iptables -vnL INPUT`... this script could feed the data to cacti or
another rrdtool/mrtg style monitoring system.
