Log Analysis Tools?

[dtc]

Being new to all of this, have a question on what you folks feel are the best tools out there for monitoring/viewing/analyzing/rotating all of the logs, like syslogd and such. Ease of setup and use are also important to me ;) It will be used on my web-server that I co-located....

I'm using RH 7.3.

I've come accross a couple already like Lire Log report, Log Master, Log Dog and such...

Either GNU or commercial apps.....Pros/cons and links would be great! :cool:

Thanks!!

I will rotate some logs (daemontools does this itself), but things like the /var/log/messages I prefer to do manually and set the append-only attribute with the following command:
chattr +a /var/log/messages

I use logwatch for reviewing many logs, and although I don't use any for Apache or Qmail, I wrote a iptables log parser (http://sourceforge.net/projects/fwreport). If you choose to use it, please provide feedback ;)
