Confluence could offer a feature for administrators to pull a report containing:

• Pages created by a user;
• Pages viewed by a user;
• Comments posted by a user;
• Pages edited by a user.

This would help administrators to measure Confluence usability.

Workarounds

The "People" feature in Confluence lets a user see what pages another user has created, updated and commented on.

1. Click People in the Confluence navigation
2. Search for the particular user and click the user card
3. Click "View all" next to the "Worked on" section
