You can use Elements to see how many users have viewed your diagrams and what rating they have left of each diagram.

If you have the Enterprise license, then every published diagram in your Space will come with the rating feature. Any user viewing the diagram will be able to mark it as either positive or negative.

This feature is available:

To evaluate the adoption of your diagrams, first select the target map and open Map Management from the right panel.

Navigate to the "published tree" of your map.

The "Adoption" column shows you number of user views, positive and negative ratings for each diagram. If you publish a new version of the diagram, the rating will be reset.
