Error while starting vtune profiler collection using root

vtune-work — Mon, 12 Sep 2022 08:42:37 GMT

I am trying to run vtune profiler from root user by,

=> source /opt/intel/oneapi/setvars.sh

After this I tried the command :

=> vtune -collect performance-snapshot sleep 5

ERROR :

[root@a1 opc]# vtune -collect performance-snapshot sleep 5
vtune: Error: The following events cannot be collected: UNC_M_CAS_COUNT.RD,UNC_M_CAS_COUNT.WR,UNC_M_PMM_RPQ_INSERTS,UNC_M_PMM_WPQ_INSERTS. Consider removing the events from the collection, loading the VTune Profiler sampling driver using the root credentials, or updating the OS kernel.
vtune: Collection failed.

And I tried to do the same collection using my normal user instead of root user, But then it worked. What changes should I make to make it work with the root user. Please help.
