Proxy Log Analysis Software

[Firewalls <Firewall () exchange ware net>]

Greetings,

I'm curious if anyone has seen good any good analysis software for proxy
log files (as generated by Netscape, Squid, and Apache proxies).
Specifically I'm looking for the ability to "sniff" out bandwidth hogs,
and visitors to questionable sites. I'd also like the ability to
generate reports for any particular internal user (based on IP address).



Any recommendations?
