AWStats – log analyzer

AWStats is short for Advanced Web Statistics. AWStats is powerful log analyzer which creates advanced web, ftp, mail and streaming server statistics reports based on the rich data contained in server logs. Data is graphically presented in easy to read web pages.

Designed with flexibility in mind, AWStats can be run through a web browser CGI (common gateway interface) or directly from the operating system command line.

Through the use of intermediary data base files, AWStats is able to quickly process large log files, as often desired.

With support for both standard and custom log format definitions, AWStats can analyze log files from Apache (NCSA combined/XLF/ELF or common/CLF log format), Microsoft’s IIS (W3C log format), WebStar and most web, proxy, wap and streaming media servers as well as ftp and mail server logs.

Features include:

• A full log analysis enables AWStats to show you the following information:
  • Number of visits, and number of unique visitors.
• • Visits duration and last visits.
• • Authenticated users, and last authenticated visits.
• • Days of week and rush hours (pages, hits, KB for each hour and day of week).
• • Domains/countries of hosts visitors (pages, hits, KB, 269 domains/countries detected, GeoIp detection).
• • Hosts list, last visits and unresolved IP addresses list.
• • Most viewed, entry and exit pages.

• • OS used (pages, hits, KB for each OS, 35 OS detected).
• • Browsers used (pages, hits, KB for each browser, each version (Web, Wap, Media browsers: 97 browsers, more than 450 if using browsers_phone.pm library file).
• • Visits of robots (319 robots detected).
• • Worms attacks (5 worm’s families).
• • Search engines, keyphrases and keywords used to find your site (The 115 most famous search engines are detected like yahoo, google, altavista, etc…), HTTP errors (Page Not Found with last referrer, …).
• • Other personalized reports based on url, url parameters, referrer field for miscellaneous/marketing purpose.
• • Number of times your site is “added to favourites bookmarks”.
• • Screen size (need to add some HTML tags in index page).
• • Ratio of Browsers with support of: Java, Flash, RealG2 reader, Quicktime reader, WMA reader, PDF reader (need to add some HTML tags in index page).

• Works from command line and from a browser as a CGI (with dynamic filters capabilities for some charts).
• Update of statistics can be made from a web browser and not only from your scheduler.
• Unlimited log file size, support split log files (load balancing system).
• Support ‘not correctly sorted’ log files even for entry and exit pages.
• Reverse DNS lookup before or during analysis, support DNS cache files.
