Free-SA is tool for statistical analysis of daemons' log files, similar to SARG. Its main advantages over SARG are much better speed (7x-20x), more support for reports, and W3C compliance of generated HTML/CSS reports. It can be used to help control traffic usage, to control Internet access security policies, to investigate security incidents, to evaluate server efficiency, and to detect troubles with configuration.License: GNU General Public License (GPL)Changes:
The license was changed to the GPLv3+. Experimental support for NetCache and Blue Coat logs via Squid 2.x native log format has been added. The log format autodetection feature has been removed because it appeared useless and slow. A 'skip_errors' experimental option for skipping erroneous log file records has been added. To specify a year value for syslog-based log formats, a SYSLOGYEAR macro was added. Other small fixes were implemented.
