[edit] SARG

SARG is a reporting utility developed to report against the Squid cache log files. It runs several scripts from the cron scheduler, then places the html files into the web directory you specify. You can also run the command 'sarg' from the linux console at any time to create a "ONE-SHOT" report.

Being that one of the logging options in DansGuardian is squid format, this makes it really easy to modify the sarg scripts to report directly against the DansGuardian logs. This will give you an easy to use report that shows where your users have been browsing, what they have been downloading, how long they have spent on the internet, how much data they have uploaded / downloaded, etc.

NOTE: If you setup sarg to point to the Squid cache log files while using DansGuardian, it will show you the sites people have been visiting, but will show all of the traffic coming from localhost (Dansguardian routes all requests through squid).
