CIFS/NFS auditing is not enabled by default, you have to enable it on each SVM, as best practice, redirect the audit log to a different small volume, set up log size and rotation. for CIFS, you can use Window evnetviewer to trace the logs.
For detailed audit request, third party auditing application is required since by native, either NetApp or windows doesn't have enough function/convince to audit CIFS shares.
I have an issue here , when enabled audit log for ntfs clients . I am able to access share(\auditlog) from client machine but unable to view from the logs from eventviewer. when i am trying to open , it says "A device attached to the system is not functioning "
