Best log file monitoring tool for ubuntu server

I'm trying to find the best Log File monitoring tool for Ubuntu 9.10 server?

Is there any web-based gui tool which could be operated by anyone, that monitor any log files?

I already tried splunk and felt it's a bit hard to operate and it's not a completely free tool


I got a demo of this tool, called Splunk, at Infosec this year. It looks pretty incredible - a viable alternative to tools like LogLogic and LogRhythm.


Splunk is great for log analysis and event identification, http://code.google.com/p/logstash/ has a web ui and can aggregate multiple servers logs.
