Usage metrics for reports across all workspaces

Hello, pborah ,thanks for your concern about this issue.

Your answer is excellent!
And I would like to share some additional solutions below.

Hi,FabricLearnFabr .I am glad to help you.

The maximum date retention period for usage metrics reports provided with power BI is 90 days, so if you want to get access to longer term report usage metrics data, you will need to access the data in other ways.

You can use PowerShell to export the audit log to a CSV file and use it as the data source for the Power BI report.
Or use Rest API to get the activity log
I hope the following related articles can help you:

Monitor usage metrics in workspaces (preview) - Power BI | Microsoft Learn
Access the Power BI activity log - Power BI | Microsoft Learn
The maximum period the API could access is 30 days.

2.You could try to customise a script (using PowerShell or a REST API) to periodically export activity log data and store it in a database. You will need to contact a programming-savvy member of your team to accomplish this.

3.Try to use other tools to help you achieve this effect.
