Missing FPolicy requests when basic attributes of a file are modified

Hi,

I have configured NetApp FPolicy on a SMB share. The FPolicy server I have developed get requests from NetApp. I am enabled all SMB filters (open, close, setattr, delete, delete_dir, rename, rename_dir).

I am using Data ONTAP 8.3.2. I modified the basic attributes of a file (changed the file to read-only). But I do not get any notification requests from NetApp.

Is there someway I can get notified when basic attributes of a file are modified?

Thanks for your help!
