W3Perl

The output is spread over HTML pages, with graphics and a sortable table.

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

One can also manage configuration files, package updates, run scripts, and see stats output.

An installer is available for Windows and Mac OS X. W3Perl is licensed under the GNU GPL.

Blocking referrer spam have been added but as it is based on a blacklist, the file must be updated regularly.
