> ipchains -A output -p tcp -d www.website.com -j ACCEPT -l

That's just going to count how many packets are sent to the server. Try
something like
ipchains -A forward -p tcp -d www.website.com 80 -y -j ACCEPT -l
The "-y" makes the big difference. This will count all connections that are
requested (doesn't mean they are established).
You should log the time and the IP though, because otherwise people can
just generate hits by constantly reloading the site.

1. ipchains log analysis tool (ipchains-db.pl)

    I have written a Perl script that parses ipchains log messages
    and optionally inserts them into a database to make sifting
    through hundreds (or thousands ;) of log messages to find
    anything that might indicate potential problems.

    If interestested, you may obtain this from:

    Please consider this an alpha release. If you do try this out,
    I would appreciate any feedback you have. Post here or e-mail
    as you see fit. I am particularly interested in bugs, problems
    and ideas for future development.

    I would also like to know what you think are good queries to
    issue to display 'interesting statistics'. (I would also like
    know how to query by date! Couldn't figure out the syntax for
    that 'where' clause. ;)
