6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <p>This module provides "journald" ErrorLog provider. It allows logging
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd error messages and CustomLog/TransferLog via systemd-journald(8).</p>

6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <p>Systemd-journald allows structured logging and therefore it is
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd possible to filter logged messages according to various variables.
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd Currently supported variables are:
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <dd>The name of the log. For ErrorLog, the value is "error_log".
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd For CustomLog or TransferLog, the value is the first argument of
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd these directives.</dd>
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <dd>Host, as set by full URI or Host: header in the request.</dd>
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <dd>If an authentication check was made, this gets set to the user
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd name.</dd>
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <dd>The path portion of the URI, or "/" if no path provided.</dd>
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <dd>The hostname of server for which the log message has been
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd generated.</dd>
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <p>These variables can be for example used to show only log messages
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <pre class="prettyprint lang-">journalctl REQUEST_URI=/index.html -a</pre>

6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd instead of a filename enables logging via systemd-journald(8)
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd if the system supports it.

6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd <p>The <code class="directive">JournaldCustomLog</code> directive enables logging
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd of CustomLog and TransferLog messages to systemd-journald.
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd Currently, systemd-journald is not designed for high-throughput logging
6c4ef4a72d9897e53365b94103f4bd819fd0d3acnd and logging access_log to systemd-journald could decrease the performance
