[Zope] How to know what are zope doing now?

Hi! Every night my Zope server has 99% cpu usage and, sometimes, the server stops to serve pages There are any way to know what the Zope server is doing in real time? I know I could look at event.log or z2.log but I would like to know the activity in real time Is this posible? How can I know what my server is doing? Thanks! -- Mis Cosas http://blogs.sistes.net/Garito
