title: how to check syslog for ubuntu docker
body: <p>I installed <a href="https://hub.docker.com/r/tutum/ubuntu/" rel="noreferrer"><code>tutum/ubuntu</code></a> in local vm's docker.</p>
  
  <p>When I login to <code>ubuntu</code> and run below command.</p>
  
  <pre><code>logger "Test Logging"
  </code></pre>
  
  <p>I can't find the file where this logged in. In my local system I can see the <code>system.log</code> or <code>syslog</code> or <code>messages</code> file in <code>/var/log</code>. But when I check <code>/var/log</code> in container, I can't find any file like this.</p>
  
  <pre><code>root@fbc4ae457ad9:~# ls -al /var/log/
  total 316
  drwxrwxr-x  6 root syslog   4096 Jun 20 16:49 .

  </code></pre>
  
  <p>I check in <code>upstart</code> and other directory, but all are empty.</p>
  
  <p>Which file I have to check for <code>systemlog</code> ?</p>
