Windows file access detail displays

Windows file access detail displays show the following types of information.

Field	Description
Object Server	The name of the subsystem server process calling the audit check function. This is always SECURITY because this is a security log.
Object Type	The type of object being accessed.
Object Name	The name (such as a file name) of the object being accessed.
New Handle ID	The new handle identifier of the open object.
Operation ID	A unique identifier associating multiple events resulting from a single operation.
Process ID	The identifier of the client process accessing the object.
Primary User Name	The user name of the user requesting the object access. When impersonation is taking place, this is the user name with which the server process is logged on.
Primary Domain	The name of the computer, or SYSTEM if the user identified by Primary User Name is SYSTEM. If the computer is a member of a Windows NT Server domain, this can also be the name of the domain containing the primary user's account.
Primary Logon ID	A unique identifier assigned when the primary user logged on.
Client User Name	Your login.
Client Domain	The name of your computer or the domain containing the client user's account.
Client Logon ID	A unique identifier assigned when the client user logged on.
Accesses	The types of accesses to the object that were attempted.
Privileges	Your privileges.

UNIX file access detail displays

UNIX file access detail displays show the same kind of information as the Windows file access detail displays, but NFS access appears instead of an object name, because the file is accessed through NFS. In addition, UNIX file access detail displays show the following information about the file that you are auditing:

The ID of the volume in which the file is located
The ID of the latest snapshot in which the file is located
The inode of the file

This information enables you to find the file using the find -inum command from an NFS client.

Unsuccessful file access detail displays

Unsuccessful file access detail displays show failed attempts to access a file. For example, an unsuccessful file access occurs when a user tries to access a file but does not have permission to access it.

The display shows the ID of the user who tried to access the file and an indication that the access attempt was unsuccessful.

Lost record event detail displays

If Data ONTAP cannot create an audit record, the lost record event detail displays give a reason, such as the following:

Internal resources allocated for the queueing of audit messages 
have been exhausted, leading to the loss of some audits.
