You need a Power BI Pro or Premium Per User (PPU) license to run and access the usage metrics data. However, the usage metrics feature captures usage information from all users, regardless of the license they're assigned.
To access usage metrics for a report, you must have edit access to the report.
Your Power BI admin must have enabled usage metrics for content creators. Your Power BI admin may have also enabled collecting per-user data in usage metrics. Read about how to enable these options in the admin portal.
Only users with admin, member, or contributor permissions can view the usage metrics report. Viewer permissions aren't enough.
