I have PowerBi Server (Jan 2019) installed on my server. I can see from the default trace that that the PowerBi Service account
NT SERVICE\PowerBIReportServer is granting execute permissions on a stored procedure
ExtendEditSessionLifetime to the
RSExecRole (within the
GRANT EXECUTE ON [dbo].[ExtendEditSessionLifetime] TO RSExecRole
This is happening frequently many times during the hour, most hours (around 50 times an hour) there doesn't seem to a pattern that I can see and I can't find any documentation online about what the stored procedure does. I can't see anything obvious in the PowerBI logfiles or the event viewer either.
What could be causing this (or is it intended behaviour?)
