WebLog Expert is a fast and powerful access log analyzer. It will give you information about your site's visitors: activity statistics, accessed files, paths through the site, information about referring pages, search engines, browsers, operating systems, and more. The program produces easy-to-read HTML reports that include both text information (tables) and charts. View the WebLog Expert sample report to get the general idea of the variety of information about your site's usage it can provide.

WebLog Expert can analyze logs of Apache and IIS web servers. It can even read GZ and ZIP compressed logs so you won't need to unpack them manually.

The log analyzer features intuitive interface. Built-in wizards will help you quickly and easily create a profile for your site and analyze it.
Flexible system of filters provides an ability to carry out deep analysis of visitors' activity. Use the filters to separate or filter out individual log entries and visitors. For example you can get information about visitors who accessed a specific page or came from a specific URL.
