No, I think I'm not going to write a new logfile parser. Better, I'm not going to write a public available logfile parser. I think I'll write one just to learn why other parsers are better :)). What I'd like to find is the common used solution to perform this task (with solution I mean some composition of scripts and software, i.e. Perl + MySQL + something else...). And I'd like to know rationales that make this solution preferable.
