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.
