ApaLogFilter is a tool - released under the GNU General Public License - which filters and manipulates web server logfiles (NCSA Combined Log Format). The purpose is
* to reduce the number of lines in the logfile to lines which are relevant for the statistics,
* to manipulate the data in the entries, so that they can be better interpreted.
The analyses itself can be done with programs like analog or webalizer. This tool Complements those by providing a preprocessing step for raising the quality of the reports.
