Ok, first off, what I wanted to achieve is monitor my home network to see bootlenecks (existing or coming) and suspicious traffic.

Opened bugzilla https://bugzilla.novell.com/show_bug.cgi?id=848276 for this
Question remaining: Is ntop the best tool for this?
I think so, but I wonder why it does not work ootb. Could be an indication for an exotic approach.
