I have been implementing AWstats log processors for various websites now. I find it really good, easy to configure maintain and use. I will be posting various scripts run/maintain config files.
Awstats can be found here:
and here are few features of awstats:
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, 266 domains/countries detected),
* Hosts list, last visits and unresolved IP addresses list,
* Most viewed, entry and exit pages,
* Files type,
* Web compression statistics (for mod_gzip),
* Browsers used (pages, hits, KB for each browser, each version, 78 browsers: Web, Wap, Media browsers…),
* OS used (pages, hits, KB for each OS, 31 OS detected),
* Visits of robots (307 robots detected),
* Search engines, keyphrases and keywords used to find your site (The 90 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, referer field for miscellanous/marketing purpose.
AWStats also supports the following features:
* Can analyze a lot of log formats: Apache NCSA combined log files (XLF/ELF) or common (CLF), IIS log files (W3C), WebStar native log files and other web, proxy, wap or streaming servers log files (but also ftp or mail log files). See AWStats F.A.Q. for examples.
* 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 ‘nearly sorted’ log files even for entry and exit pages,
* Reverse DNS lookup before or during analysis, support DNS cache files,
* Country detection from IP location (geoip) or domain name.
* WhoIS links,
* A lot of options/filters and plugins can be used,
* Multi-named web sites supported (virtual servers, great for web-hosting providers),
* Cross Site Scripting Attacks protection,
* Several languages. See AWStats F.A.Q. for full list.
* No need of rare perl libraries. All basic perl interpreters can make AWStats working,
* Graphical and framed reports,
* Look and colors can match your site design,
* Help and tooltips on HTML reported pages,
* Easy to use (Just one configuration file to edit),
* Absolutely free (even for web hosting providers), with sources (GNU General Public License),
