<p>The systemd journal provides Cockpit with indexed log data. This log data
    is found on the Journal page, as well as in various other places when configuring
    services, storage, networking etc.</p>
<p>Cockpit accesses Journal data via the
    <a class="ulink" href="https://www.freedesktop.org/software/systemd/man/journalctl.html" target="_top"><code class="code">journalctl</code></a>
    command. Similar tasks can be performed at the command line:</p>
<pre class="programlisting">
$ <span class="command"><strong>sudo journalctl -f -u docker</strong></span>
