[Zope] STATISTIC] Is there a way to have statistic of a Zope site use ?

[FrŽdŽric Lemaitre]

Hello,
A have my Intranet Zope production site since few days (GREAT !!!).

I would like to know if there is a way (without manualy analyse the 
access log) to know :
 - How many users have been authentified since the site is on-line ?
 - How many times a page has been seen ?
 - The top visited pages ?
 - Statistic of when, how much, etc.. users use the site ?

In fact, is there a Zope functionnality to do something like that 
whithout using an other software (like Webtrend) ?

Thanks in advance.
Fred.
