Log analyser for general use ?

[Nicolas Bouthors <nbouthors@ghs.fr>]

Hi,

I'm looking for a program that would allow the watching of logfiles (mainly 
syslog), and could choose to perfom an action (like sending a mail or other) 
when a certain line/sequence appears in the files.

Idealy it would be easily configurable through regexps, run as a daemon and 
be able to watch any number of log files...

I already found about 
  - Logsurfer (http://www.cert.dfn.de/eng/logsurf/)
  - Swatch (http://oit.ucsb.edu/~eta/swatch/)
  - and many other restricted to *webserver* logs (which is not what I want)

Any other idea/suggestion apreciated.

Thanks,
	Nico
