<h1>Logging configuration<a class="headerlink" href="#logging-configuration" title="Permalink to this headline">¶</a></h1>
<p>Use your Nextcloud log to review system status, or to help debug problems. You may adjust logging levels, and choose between using the Nextcloud log or your syslog.</p>
<div class="section" id="parameters">
<h2>Parameters<a class="headerlink" href="#parameters" title="Permalink to this headline">¶</a></h2>
<p>Logging levels range from <strong>DEBUG</strong>, which logs all activity, to <strong>FATAL</strong>, which logs only fatal errors.</p>
<ul class="simple">
<li><strong>0</strong>: DEBUG: All activity; the most detailed logging.</li>
<li><strong>1</strong>: INFO: Activity such as user logins and file activities, plus warnings, errors, and fatal errors.</li>
<li><strong>2</strong>: WARN: Operations succeed, but with warnings of potential problems, plus errors and fatal errors.</li>
<li><strong>3</strong>: ERROR: An operation fails, but other services and operations continue, plus fatal errors.</li>
<li><strong>4</strong>: FATAL: The server stops.</li>
</ul>
<p>By default the log level is set to <strong>2</strong> (WARN). Use <strong>DEBUG</strong> when you have a problem to diagnose, and then reset your log level to a less-verbose level as <strong>DEBUG</strong> outputs a lot of information, and can affect your server performance.</p>
<p>Logging level parameters are set in the <code class="file docutils literal"><span class="pre">config/config.php</span></code> file, or on the Admin page of your Nextcloud Web GUI.</p>
<div class="section" id="nextcloud">
<h3>Nextcloud<a class="headerlink" href="#nextcloud" title="Permalink to this headline">¶</a></h3>
<p>All log information will be written to a separate log file which can be
viewed using the log viewer on your Admin page. By default, a log
file named <strong>nextcloud.log</strong> will be created in the directory which has
been configured by the <strong>datadirectory</strong> parameter in <code class="file docutils literal"><span class="pre">config/config.php</span></code>.</p>
<p>The desired date format can optionally be defined using the <strong>logdateformat</strong> parameter in <code class="file docutils literal"><span class="pre">config/config.php</span></code>.
By default the <a class="reference external" href="http://www.php.net/manual/en/function.date.php">PHP date function</a> parameter “<em>c</em>” is used, and therefore the
date/time is written in the format “<em>2013-01-10T15:20:25+02:00</em>”. By using the
date format in the example below, the date/time format will be written in the format
“<em>January 10, 2013 15:20:25</em>”.</p>
