## Name

vfs_full_audit — record Samba VFS operations in the system log

## Synopsis

`vfs objects = full_audit`

## DESCRIPTION

This VFS module is part of the samba(7) suite.

The `vfs_full_audit` VFS module records selected client operations to the system log using syslog(3).

`vfs_full_audit` is able to record the complete set of Samba VFS operations:

In addition to these operations, `vfs_full_audit` recognizes the special operation names "all" and "none ", which refer to all the VFS operations and none of the VFS operations respectively.

`vfs_full_audit` records operations in fixed format consisting of fields separated by '|' characters. The format is:

    		smbd_audit: PREFIX|OPERATION|RESULT|FILE

The record fields are:

- `PREFIX` - the result of the full_audit:prefix string after variable substitutions

- `OPERATION` - the name of the VFS operation

- `RESULT` - whether the operation succeeded or failed

- `FILE` - the name of the file or directory the operation was performed on

This module is stackable.

## OPTIONS

vfs_full_audit:prefix = STRING

  Prepend audit messages with STRING. STRING is processed for standard substitution variables listed in smb.conf(5). The default prefix is "%u|%I".

vfs_full_audit:success = LIST

  LIST is a list of VFS operations that should be recorded if they succeed. Operations are specified using the names listed above.

vfs_full_audit:failure = LIST

  LIST is a list of VFS operations that should be recorded if they failed. Operations are specified using the names listed above.

full_audit:facility = FACILITY

  Log messages to the named syslog(3) facility.

full_audit:priority = PRIORITY

  Log messages with the named syslog(3) priority.

## EXAMPLES

Log file and directory open operations on the [records] share using the LOCAL7 facility and ALERT priority, including the username and IP address:

            [records]
    	path = /data/records
    	vfs objects = full_audit
    	full_audit:prefix = %u|%I
    	full_audit:success = open opendir
    	full_audit:failure = all
    	full_audit:facility = LOCAL7
    	full_audit:priority = ALERT
