Apache2GDL: How Visitors Browse Your Site
Apache2GDL is a Perl script that automatically generates visitor movement graphs from Apache log files, thus helping you answer the following questions:
- Which paths do visitors to your site take to get from page A to page B?
- Which paths are more popular than others?
- Are there one-way paths and dead-end pages?
- And the ever-popular: Which pages get the most hits?
Examples
|
Nodes represent pages of a given Web site while edges represent visitor movements between them. Node colors and edge thicknesses reflect the number of visitors that have visited a particular page or followed a particular path. Optionally, edges can be labeled with the number of visitors that have followed them.

Installation
> gunzip apache2gdl.pl.gz
> chmod 755 apache2gdl.pl
Usage
> cat <input log> | apache2gdl.pl [URL pattern] > <output graph>
The URL pattern should be set to the
name of your domain (example.com) or a particular directory
within that domain (example.com/something). Example:
> cat /var/log/absint_com_2004_access.log |
apache2gdl.pl absint.com/aisee/download >
graph.gdl
You can specify a list of directories as well:
> cat /var/log/aisee_com_access.log |
apache2gdl.pl aisee.com/gdl aisee.com/svg aisee.com/png >
graph.gdl
Instead of writing the graph to a file, you can directly pipe it through aiSee and get a mapped SVG or PNG image of the layout. Examples:

Known issues
Including a trailing slash in the URL pattern
may result in a different graph being produced.
