W3Perl is an open source analytics application that doesn’t require any code to be inserted into websites for monitoring. Rather, it goes through the log files generated on the server-side and creates the reports in real-time.

The application is not limited to web servers and it can also render the logs of  FTP, Squid, CUPS and mail servers.

Watch your stats in real time. Updates are computed every minute and you can change integration time (default is 60 seconds) and length (default 60 minutes). Hosts are displayed with their pages list in chronological order.
