title: Logging in nodejs using bunyan logger
body: <p>I am initializing the bunyan logger in my nodejs code as below:</p>
  <pre><code>var log = bunyan.createLogger({
      name: 'myapp',
      stream: process.stdout,
      level: 'info'
  });
  </code></pre>
  <p>This is from the bunyan docs at <a href="https://www.npmjs.org/package/bunyan" rel="nofollow noreferrer">https://www.npmjs.org/package/bunyan</a></p>
  <p>The docs mention:</p>
  <blockquote>
  <p>By default, log output is to stdout and at the &quot;info&quot; level.</p>
  </blockquote>
  <p>What I am wondering is: shouldn't the logger be asking me for a file name where I want things logged.
  Where is the logging happening?</p>
