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.
When will get this feature?
