<h2><a name="structured" id="structured">Structured logging</a></h2>
<p>Systemd-journald allows structured logging and therefore it is
possible to filter logged messages according to various variables.
Currently supported variables are:
</p>
<dl>
<dt><code>LOG</code></dt>
<dd>The name of the log. For ErrorLog, the value is "error_log".
For CustomLog or TransferLog, the value is the first argument of
these directives.</dd>
<dt><code>REQUEST_HOSTNAME</code></dt>
<dd>Host, as set by full URI or Host: header in the request.</dd>
<dt><code>REQUEST_USER</code></dt>
<dd>If an authentication check was made, this gets set to the user
name.</dd>
<dt><code>REQUEST_USERAGENT_IP</code></dt>
<dd>The address that originated the request.</dd>
<dt><code>REQUEST_URI</code></dt>
<dd>The path portion of the URI, or "/" if no path provided.</dd>
<dt><code>SERVER_HOSTNAME</code></dt>
<dd>The hostname of server for which the log message has been
generated.</dd>
</dl>
<p>These variables can be for example used to show only log messages
for particular URI using <code>journalctl</code>:
</p>
<pre class="prettyprint lang-">journalctl REQUEST_URI=/index.html -a</pre>
<p>For more examples, see systemd-journalctl documentation.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="examples" id="examples">Examples</a></h2>
<p>Using <code>journald</code> in ErrorLog directive (see <code class="module"><a href="../mod/core.html">core</a></code>)
instead of a filename enables logging via systemd-journald(8)
if the system supports it.
</p>
<pre class="prettyprint lang-config">ErrorLog journald</pre>
<p>Using <code>journald</code> as an error log provider in CustomLog
directive (see <code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code>) enables
logging via systemd-journald(8) if the system supports it.
</p>
<pre class="prettyprint lang-config">CustomLog "journald" "%h %l %u %t \"%r\" %>s %b"</pre>
<div class="warning"><h3>Performance warning</h3><p>
Currently, systemd-journald is not designed for high-throughput logging
and logging access_log to systemd-journald could decrease the performance
a lot.
