	<title>DESCRIPTION</title>

	<para>This VFS module is part of the
	<citerefentry><refentrytitle>samba</refentrytitle>
	<manvolnum>7</manvolnum></citerefentry> suite.</para>

	<para>The <command>vfs_smb_traffic_analyzer</command> VFS module logs
	client write and read operations on a Samba server and sends this data
	over a socket to a helper program, which feeds a SQL database. More
	information on the helper programs can be obtained from the
	homepage of the project at:
	http://holger123.wordpress.com/smb-traffic-analyzer/
	</para>
	<para><command>vfs_smb_traffic_analyzer</command> currently is aware
	of the following VFS operations:</para>

	<simplelist>
        <member>write</member>
        <member>pwrite</member>
	<member>read</member>
	<member>pread</member>
	</simplelist>

	<para><command>vfs_smb_traffic_analyzer</command> sends the following data
	in a fixed format seperated by a comma through either an internet or a
	unix domain socket:</para>
	<programlisting>
	BYTES|USER|DOMAIN|READ/WRITE|SHARE|FILENAME|TIMESTAMP
	</programlisting>

	<para>Description of the records:

	<itemizedlist>
	<listitem><para><command>BYTES</command> - the length in bytes of the VFS operation</para></listitem>
	<listitem><para><command>USER</command> - the user who initiated the operation</para></listitem>
	<listitem><para><command>DOMAIN</command> - the domain of the user</para></listitem>
	<listitem><para><command>READ/WRITE</command> - either "W" for a write operation or "R" for read</para></listitem>
	<listitem><para><command>SHARE</command> - the name of the share on which the VFS operation occured</para></listitem>
	<listitem><para><command>FILENAME</command> - the name of the file that was used by the VFS operation</para></listitem>
	<listitem><para><command>TIMESTAMP</command> - a timestamp, formatted as "yyyy-mm-dd hh-mm-ss.ms" indicating when the VFS operation occured</para></listitem>
	</itemizedlist>

	<variablelist>

		<varlistentry>
                <term>smb_traffic_analyzer:mode = STRING</term>
                <listitem>
                <para>If STRING matches to "unix_domain_socket", the module will
		use a unix domain socket located at /var/tmp/stadsocket, if
		STRING contains an different string or is not defined, the module will
		use an internet domain socket for data transfer.</para>

                </listitem>
                </varlistentry>


		<varlistentry>
		<term>smb_traffic_analyzer:host = STRING</term>
		<listitem>
		<para>The module will send the data to the system named with
		the hostname STRING.</para>

		</listitem>
		</varlistentry>

		<varlistentry>
		<term>smb_traffic_analyzer:port = STRING</term>
		<listitem>
		<para>The module will send the data using the TCP port given
		in STRING.
		</para>
		</listitem>
		</varlistentry>
		<varlistentry>
		<term>smb_traffic_analyzer:anonymize_prefix = STRING</term>
		<listitem>
		<para>The module will replace the user names with a prefix
		given by STRING and a simple hash number.
		</para>

		</listitem>
		</varlistentry>

		<varlistentry>
		<term>smb_traffic_analyzer:total_anonymization = STRING</term>
		<listitem>
		<para>If STRING matches to 'yes', the module will replace
		any user name with the string given by the option 
		smb_traffic_analyzer:anonymize_prefix, without generating
		an additional hash number. This means that any transfer data
		will be mapped to a single user, leading to a total 
		anonymization of user related data.</para>
