Usage Metrics Report for 12 months

Hi az111121 ,

If your Power BI admin has enabled usage metrics for content creators and has also enabled collecting per-user data in usage metrics, you can access usage metrics with a Power BI pro license and edit rights to the app workspace are required to.

It won't show the usage metrics a long time ago such as 12 months you mentioned.

For "Workspaces": It contains usage metrics for that content for the last 30 days.

For "My workspace": When you select Usage metrics or the icon next to a dashboard or report, Power BI generates a pre-built report with usage metrics for that content for the last 90 days. 

Please refer to the following documents.
