Web Dynpro Logging

I was wondering if there was any default logging done by the portals when a web dynpro application is accessed.

I have a client that claims all their iviews are logging somewhere each time they are accessed by a user so they can see who accessed what. However they claim that the Web Dynpro iViews we have developed for them do not do this logging.

Is there any setting to enable this client access type of logging or does it need to be coded directly into the web dynpro application?

Thanks in advance.
