What is Modlogan?
Modlogan is a modular logfile analyzer which is currently able to parse ftp-, webserver and squid logs. The generated output can be viewed by a web browser (->moglogan, webalizer) or your favorite text editor (->text). The different input and output modes are provided by some surrounding plugins. For example the modlogan output plugin provides three different menu structure for the same colourfull output while the output which is generated by the webalizer output plugin looks similar to the output generated by the original Webalizer known from http://www.mrunix.net/webalizer. The input is handled the same way. One plugin is for the web server logs, the next is for xferlog from FTP-servers like WuFTP and the third input plugin is a NULL plugin which does nothing (but this perfectly :).
