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.
