<p>Several sites have wanted a way to provide central logging
of job status and/or information. In order to do this, the
following functionality is implemented in <b class=
"APPLICATION">LPRng</b>.</p>
<div class="SECT1">
<h1 class="SECT1"><a name="LOGGER" id="LOGGER">21.1. Logger
Network Communication</a></h1>
<p>Options used:</p>
<ul>
<li>
<p><tt class=
"LITERAL">logger_destination=</tt><span class=
"emphasis"><i class="EMPHASIS">logger information
destination</i></span></p>
</li>
<li>
<p><tt class="LITERAL">logger_pathname=</tt><span class=
"emphasis"><i class="EMPHASIS">pathname of temp file for
log information</i></span></p>
</li>
<li>
<p><tt class="LITERAL">logger_max_size=</tt><span class=
"emphasis"><i class="EMPHASIS">max size in K of temp file
for log information</i></span></p>
</li>
<li>
<p><tt class="LITERAL">logger_timeout=</tt><span class=
"emphasis"><i class="EMPHASIS">time between connection
attempts</i></span></p>
</li>
</ul>
<p>The printcap/configuration variable <tt class=
"LITERAL">logger_destination</tt> specifies a destination in
the standard <tt class="LITERAL">host%port</tt> notation used
by <b class="APPLICATION">LPRng</b>. Host is the destination
host, and can be a name or IP address. Port is the port on
the destination host. A TCP/IP connection is made to the
indicated port.</p>
<p>Log information is save in a temporary file specified by
<tt class="LITERAL">logger_path</tt>, and up to <tt class=
"LITERAL">logger_max_size</tt> K bytes of data will be
saved.</p>
<p>If a connection cannot be made to the <tt class=
"LITERAL">logger_destination</tt>, then every <tt class=
"LITERAL">logger_timeout</tt> seconds a new connection
attempt will be made. If <tt class=
"LITERAL">logger_timeout</tt> is 0, then a connection attempt
will be made every time new data arrives to be logged.</p>
