NFS AUDIT LOG ENABLING

Netapp_maniac — Wed, 04 Jun 2025 10:22:56 GMT

Hello Folks ,

Can someone guide how to enable audit logs for CIFS shares on Ontap CVO ?

Do it has to be NFS/CIFS audit enabling ? It is different for NFS and CIFS ?

Thanks in Advance !

Hey Dude,

the Guide what you are looking for is this: https://docs.netapp.com/ontap-9/topic/com.netapp.doc.dot-cifs-nfs-audit/home.html , but are you using CVO Service or the fully CVO?

Could you please help me understand what will be the unix path name as per below command :

vserver audit create -vserver <vserver> -destination <unix path> -rotate-size <size>

Thanks !!

You have to create a volume for the log. Than you have to mount the Volume under junction path.

Example for the Command

vserver audit create -vserver vs1 -destination /audit_log

Volume security style has to be NTFS OR UNIX ?

So will the logs be available in windows/unix machine when the volume is mounted to it ?

Thanks !!

Depends on the System that you want to use to viewing the logs..

You can mount the volume to look into the logfiles..

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.

you have to install NFS client for Windows to review any NFS export.
