We use a combo of syslog-ng+swatch for our filtering which can do
quite a lot for free, any more tips on what messages people are
looking for on Cisco networks would be appreciated.

> If you're looking for a supported, proprietary product, check out Solarwinds Orion - much more than just a syslog repository, though.  You are able to store syslogs in a SQL database, create rules for syslogs based upon source IP, source hostname, message type (%LINK-4-ERROR, etc.), and message contents.  You can also do fancy things like forward the syslog to another syslog server, send an email/page, modify the message, and do time-of-day rules.  On the downside, if all you need is a syslog server, you have to pay for the entire Orion suite, which is pretty expensive.
