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\.
.PP
vfs_full_audit
records operations in fixed format consisting of fields separated by \'|\' characters\. The format is:
.sp
.RS 4
.nf
		smbd_audit: PREFIX|OPERATION|RESULT|FILE
	
.fi
.RE
.PP
The record fields are:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
PREFIX
\- the result of the full_audit:prefix string after variable substitutions
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
OPERATION
\- the name of the VFS operation
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
RESULT
\- whether the operation succeeded or failed
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3

This module is stackable\.
.SH "OPTIONS"
.PP
vfs_full_audit:prefix = STRING

\fBsmb.conf\fR(5)\. The default prefix is "%u|%I"\.
.RE
.PP
vfs_full_audit:success = LIST
.RS 4
LIST is a list of VFS operations that should be recorded if they succeed\. Operations are specified using the names listed above\.
.RE
.PP
vfs_full_audit:failure = LIST
.RS 4
LIST is a list of VFS operations that should be recorded if they failed\. Operations are specified using the names listed above\.
.RE
.PP
full_audit:facility = FACILITY
.RS 4
Log messages to the named
\fBsyslog\fR(3)
facility\.
.RE
.PP
full_audit:priority = PRIORITY
.RS 4
Log messages with the named
\fBsyslog\fR(3)
priority\.
