We are working on this feature. All file access events will be audited in the product, whether those events ultimately result in a person viewing the file or not. The data about who did what, when and from where, with every file stored in SharePoint will be made available through a compliance center UI and also through APIs that the customer or 3rd party analytics provider can access directly.
We are working on many of these report areas right now. We have a tenant-wide user activity report in development right now. The next report we will work on will be a tenant-wide site usage and activity report. After that, we will look at various other tenant-wide reports, including page-views, and storage metrics.
We are currently working on this report. We will have a OneDrive site usage report that not only shows how much storage each OneDrive user is consuming, but also how many files they have on the site, and how much activity that site is experiencing.Anonymous commented
It would also be nice to have the option to list the file names for each users on the report
