Native auditing - NFS - Events not generated for some events


I have 9.0 ONTAP simulator and have created A NFS volume. I have done the auditing for the SVM. I have a few questions regarding the Native auditing for NFS 

1) Is the Auditing inheritance not possible for  NFS 

2) when I am ceating a File/Folder I am not seeing any events.


3)No events generated for file read or File open 


Thanks ,
