Analog

Analog is a free program used to analyze the log files from Web servers. It tells you which pages are most popular, which countries people are visiting from, which sites they tried to follow broken links from, etc.

Analog is considered the most popular log analysis tool on the Internet. Users report no problems with log files as large as 25GB.

There are hundreds of options producing 27 different reports for those who want to do things differently. It can also output in any of 30 different languages.

The program is written in standard C, and should compile on almost any machine with a C compiler. It's been tested under Windows (3, 95 & NT), DOS, Mac, lots of flavors of Unix, OS/2, VMS, Acorn RiscOS, BeOS & BS2000/OSD.

Analog can read almost any type of log file. It has built-in knowledge about the common format, NCSA combined format, referrer log, browser log, W3 extended format, Microsoft IIS format, Netscape, WebSTAR and Netpresenz formats: but the user can specify other formats.
