I am currently using Kiwi syslog server and a product called FireGen Log Analyzer for Cisco PIX. Firegen does not currently have support for PIX 7.x but I am analyzing PIX 7.x logs and it works fine. Firegen has lots of schedule and adhoc capabilities and I have found it to be a very valuable tool to diagnose issues and, in general, to see what is happening on a day to day basis on our Internet connection. The website URL is http://www.eventid.net/firegen
They do have an eval that is functionally limited - we licensed it since it wasn't very costly.
