Chapter 23. Creating a Web Server > Interpreting Web Server Log Files

Interpreting Web Server Log Files

An abundance of log analysis software is available for Unix operating systems (and thus Tiger). Log analysis is more of an art than a science. As you've seen by looking at the log file formats, you can determine the remote host, requested resource, and time of request from the log file. Unfortunately, many analysis packages try to go even further by providing information on how long visitors were at your page, or where (geographically) they are located. Neither of these pieces of information is tracked in the Apache logs.

Understanding Web Statistics

To determine how long someone has been at your site, the analysis software must look at all accesses and determine which are related, and the amount of time between them. This is entirely guesswork on the part of the server. Assume that a user opens her browser, views a page, walks away for 15 minutes, and then accidentally clicks on another page before closing her browser. If the software is set with a session timeout period greater than 15 minutes, it sees two separate hits on the page. The software assumes that the user spent at least 15 minutes reading both pages and registers that the browser spent 30 minutes on the site. In reality, only a minute or two was spent looking at the site content.
