• December 19th 2002: AC.log Pro (shareware) has been released - see for yourself how much AC.log has improved in the last two years.

While AC.log will continue to be available for free, all future development will go into AC.log Pro. Check it out!

What It Does

AC.log is a program written in Perl 5 that analyses a web server log file (standard and combined format). From this information it generates some standard reports such as

Downloaded files by number of requests File types by number of requests (shows volume, too) Requesting host by number of requests (shows last access, too) HTTP version, result code (percentages) Browsers broken down by name and version Operating systems broken down by name and version Referrers by number of requests Distribution of requests over the day, week

But wait, there's more! AC.log analyses the behaviour of your visitors. It tells you

From where they came to your site On which page they entered it Which pages they viewed most often How long they were spending on each page The path they took through the site (yet to be done) From which page they where leaving How long the average session lasted

These all are features which you'll normally only find in pretty expensive tools, but AC.log does it for free.

AC.log does not:

	produce fancy graphics, but provides clear textual information
	generate 273 exotic reports, but gives you the most relevant statistics
	require Windows, but runs on any systems that runs Perl 5+
	work too fast if the log file exceeds about 30,000 entries (in the current version). On a 366MHz Pentium III with 128MB RAM it does about 1000 entries/sec under 30,000 entries, and about 400 entries/sec above that.
	burn a hole in your pocket, but is available for free

What It Needs

AC.log runs on any operating system provided Perl 5 or higher is installed.

What It Costs

AC.log is freeware, so it costs nothing.
