Track usage of Adobe Analytics among users

As an administrator, I'm sometimes asked to assess the maturity of our analytics users (i.e. their familiarity with and usage of Adobe Analytics and the various reports) .  One of the things I'd like to measure is how often a given user has accessed a particular report.

To date, I can only see login statistics that show overall logins, but I know of no way to measure tool usage beyond that.

We also send emails with report links to a group of users and would love to know whether these reports are being consumed or are orphans that need some attention.

Does anyone else have this issue?  Would love to hear feedback on this.

Cheers,

Chris
