We have google analytics on our Xerte installation which adds a bit of detail but you're still limited to the number of page views. For example, we were able to see our top resources, but the page views include a lot of 'testing' views and there's no breakdown around staff/student use. We could see the difference between new and returning users (although again, not sure how accurate this is, say if someone visits from different devices?).
We're now trying in earnest to get the xAPI dashboard set up so that we can get more details about the actual usage within projects. This should help tutors understand how their resurces are being used, and then can adapt them more effectively. I'm not sure if there will also be benefits at the 'admin' level but I'll let you know! We're setting up a Learning Record Store (open source) which will be connected to our Xerte instance (we're testing it with version 3.11 which we want to update to).
