[Zope] Site statistics

Hello, I was just wondering if Zope logs who visits what on a site ??? Usually everything that happens on your webpages (when you e.g. use apache) ends up in you webservers access_log. But does ZServer logs the same ? If so - has anyone created a product to get this data out of the log files and display them on a webpage ?? Before I started on Zope, I was using something called webalizer. Or - is it hard to "analyze" a log file and display the data from it ??? Regards, Gitte Wange
