W3Perl

From Wikipedia, the free encyclopedia

W3Perl is a free logfile analyser, which can parse Web/FTP/RealServer or Squid files. Most major web logfile formats are supported (CLF/ECLF/NECLF (Unix), IIS/W3C (Microsoft)), as well as splitted/compressed files. Output are spread over html pages, with graphics and sortable table. Stats can be run from a single command line or from a web browser.

Essential features like hosts, pages, scripts, countries, filetype, traffic, hourly, daily, weekly, monthly , referer, user agent, error are available along with other specific W3Perl stats like real-time, session, virus stats.

W3Perl have an administration interface which allow building configuration files from a web interface. You can also manage your configuration files, update the package, run the scripts and see stats output.

Written in Perl, W3Perl can be installed on any operating system supporting Perl. So it can be installed on Unix/Windows or Macintosh server. Windows users have a specific installer thanks to NSIS.

W3Perl is licensed under the GNU GPL.

Running the scripts from the administration interface should be restricted with login/password. Blocking referrer spam have been added in the latest version but as it is based on a blacklist, you'll need to update this file. Real-time stats can only run once to prevent someone to overload the server.

There are several other free package available.

  • Analog (program) is written in C and so is really fast but it lacks some important features like session stats.
  • AWStats is widely used and very powerful but still lacks some W3Perl features.
  • phpMyVisites is a set of PHP scripts with a MySql database.
  • Webalizer is offered by many ISPs as it is fast and simple. The package hasn't had any updates since 2002.
