AWStats - Free log file analyzer for advanced statistics (GNU GPL)

I install this on my Server, lets see how it works...

AWStats

AWStats is a free powerful and featureful tool that generates advanced web, streaming, ftp or mail server statistics, graphically. This log analyzer works as a CGI or from command line and shows you all possible information your log contains, in few graphical web pages. It uses a partial information file to be able to process large log files, often and quickly. It can analyze log files from all major server tools like Apache log files (NCSA combined/XLF/ELF log format or common/CLF log format), WebStar, IIS (W3C log format) and a lot of other web, proxy, wap, streaming servers, mail servers and some ftp servers.
Take a look at this comparison table for an idea on features and differences between most famous statistics tools (AWStats, Analog, Webalizer,...).
AWStats is a free software distributed under the GNU General Public License. You can have a look at this license chart to know what you can/can't do.
As AWStats works from the command line but also as a CGI, it can work with all web hosting providers which allow Perl, CGI and log access.

AWStats plugins

Plugins are .pm files you can put in your AWStats plugins directory to add new features.
Note that you must enable the plugin by adding a new line in your config files to make it works (See LoadPlugin parameter).

Standard free plugins : tooltips, decodeutfkeys, ipv6, hashfiles, geoip, geoipcity, userinfo, hostinfo, clusterinfo, urlalias, timehires, timezone, rawlog, graphapplet
Other plugins (require other licensed product to work) : geoip_region_maxmind, geoip_isp_maxmind, geoip_org_maxmind,

Other AWStats contribs/tools/package


All following files/products were developped and submitted by contributors. I haven't tried them, so I can't tell you if they work and how they work...
They can enhance AWStats use or save you time giving you a start for a new development.

Other tools:

Replacement Frontend:

BetterAWStats is a PHP Frontend to show you AWStats data file differently.

Other Non AWStats contribs/tools (not related to AWStats but related to log analysis)

maillog2commonlog.pl converts mail logs in smail or qmail format to the common log format. Note that if you want to analyze, with AWStats, mail log files from postfix, sendmail or qmail, a better solution is to use instead maillogconvert.pl preprocessor (See AWStats F.A.Q about analyzing mail logs).
Joey Hess, freeware.
maillogconv.pl is another mail log processor that can be used to change mail log files into a log file that AWStats can understand.
Note that a derivated and enhanced tool called maillogconvert.pl is provided with AWStats since 5.7. See F.A.Q about analyzing mail logs to know how to setup AWStats with maillogconv.pl or maillogconvert.pl to analyze Postfix, Sendmail, Qmail or MDaemon log files.
mlc is another postfix mail logs converter (written in C). Try it if the maillogconvert.pl tool provided with AWStats does not work on your postfix log file.
access_referer_agent2combined.pl is a perl script that converts a directory of common log format (CLF) access-files, referer-files and agent-files to a single combined.log This is usefull if you have seperate access/referer/agent logfiles and want to use all features of a loganalyzer that require a combined log file.
anonlog "anonymizes" your logfile by encoding sensitive information.
