BW 7 - How do I measure user navigations ?

The BW 3.5 technical content had a key figure that allowed me to measure user navigations, which is very useful when I want to identify those users who are 'analytic'... changing drilldowns, creating and maintaining ad hoc queries, and so forth.

But the BW 7 technical content is rather perplexing, and SAP-typical poorly documented. Can anyone recommend a technical content infocube and key figure that will work for my needs ?
