>Power BI Report Server
On the SQL Server database server where PBI is installed, there is a ReportServer database (or similar name, depending on how it was configured). There are execution logs.....and a view called ExecutionLog3 that you can run.
Here's one example of how to use it....you might have to adjust it....but if you go run a few reports and then look at this view, you'll get the idea.
SELECT ItemPath, Username, count(*) , min(timestart), max(timeend)
FROM [ReportServerpbi].[dbo].[ExecutionLog3]
where username not in ( names that you want to exclude ) and requesttype = 'Interactive'
group by itempath , username
order by count(*) desc
