The month of March 2014 marks the (possibly) definitive stop for LLOOGG, a service for real-time Web traffic analysis that was appreciated quite a lot by Sir Arthur for its simplicity and for giving an extremely clear picture of the site’s visitors activity. The service has been closed, the developers say, the lloogg.com domain name is on sale and the source code for the server-side application has been released on GitHub for everyone to download and review.
UPDATE (03/28/2014): Unfortunately LLOOGG has been closed down by its creators as explained in this news, hence the following guide has lost all its practical usefulness.
Among the offers of free on-line tools for analyzing web traffic one can find anything. There are services capable of giving an embarrassing amount of data and statistics, but who already has a good quality collector on the server of his host maybe could like to use something less verbose, focused more on the (nearly) real-time representation of basic information on the site visitors activities. Something like LLOOGG.
