Microsoft SharePoint Analytics
We get a view into SharePoint activity using Microsoft SharePoint Analytics by looking at the Files and Users views. It is out of the box services available within Microsoft SharePoint Online in Cloud.
This can simply be enabled by the Site admin from the admin center, Go to the Reports > Usage page.
From the Select a report drop-down, select SharePoint > Activity.
The Pages view shows the number of unique pages visited by users as mentioned in the figure 15.
