<p>Below is a sample logging configuration file. This file can be tweaked to control how your
homeserver will output logs. The value of the <code>log_config</code> option in your homeserver config
should be the path to this file.</p>
<p>To apply changes made to this file, send Synapse a SIGHUP signal (or, if using <code>systemd</code>, run
<code>systemctl reload</code> on the Synapse service).</p>
<p>Note that a default logging configuration (shown below) is created automatically alongside
the homeserver config when following the <a href="../../setup/installation.html">installation instructions</a>.
It should be named <code>&lt;SERVERNAME&gt;.log.config</code> by default.</p>
<p>Hint: If you're looking for a guide on what each of the fields in the &quot;Processed request&quot; log lines mean,
see <a href="../administration/request_log.html">Request log format</a>.</p>

# This is a YAML file containing a standard Python logging configuration
# dictionary. See [1] for details on the valid settings.
#
# Synapse also supports structured logging for machine readable logs which can
# be ingested by ELK stacks. See [2] for details.
