Thanks, Caton - that's super helpful. I need to hone my searching skills in the JW spaces, clearly.
We're in the cloud so I'll see how far we can push it (we miss having the DB local so we can run these) and will look to the API doc if we get stuck. Having the actual query to work from in that thread is a great starting point.
To expand on Caton's reply - the data you seek is in the DES (and therefore, also in InSite). So every view of Overview pages, Activity pages, and Content within that Place is written as a row to the DES that records the timestamp of the view (DES Activity), what was viewed (Object ID in the DES) and who viewed it (Actor ID in DES equals Jive ID of the viewing user).
So you will be able to put together an InSite Custom View (CV - our queries) that will rank your visitors by number of views (can also combine Place Overview/Activity views with Content views, for your specified time period. Once built, save it and run it whenever you need it. That CV would also put you one step away from unique views for the Place plus Content, in a time period - something we also get asked about frequently.
Hope that helps.
