Power BI Service Copilot Usage Metrics (User-level)

Hi JakeHRogers​,

Thank you for reaching out to Microsoft Fabric Community.

For user-level Power BI Copilot activity, use Microsoft Purview audit logs. Search for CopilotInteraction events and identify Power BI interactions using the application identity Copilot.Fabric.CopilotforPowerBI . These records provide user identity and event timestamps.

For automated collection, use the Office 365 Management Activity API with the Audit.General  feed. Validate the returned events for both standalone Copilot and the report Copilot pane to confirm which context fields are available.

For reference, follow the below documentation:
Audit logs for Copilot and AI applications | Microsoft Learn
Office 365 Management Activity API reference | Microsoft Learn

Thanks and regards,
