Zope/Plone usage statistics

Since a Zope access log (Z2.log) has the same format as an Apache access log, Apache log analyzers will probably work for Zope/Plone too. I have tried AWStats and Webalizer and they both worked w/o needing to set anything special. I prefer Webalizer because:

• It’s fast. (We have a 700 MB log. Webalizer took 70 seconds but AWStats took 10+ minutes.)
• It’s easy to use. (No configuration was needed in my case.)
• Output is in the form of a bunch of static files (HTML, PNG), so no need to set up a CGI script just to view the stat.
