title: how to set a default loglevel in slf4j logback.xml when an invalid log level is specified
body: <p>is something like the following available ?</p>
  <pre><code>&lt;logger name=&quot;mylogger&quot; level=&quot;ERROR&quot; defaultLevel=&quot;INFO&quot;&gt;
  </code></pre>
  <p>So when someone changes the logger configuration in run time with an invalid log level (example: in case of a typo) it should log with loglevel INFO.</p>
  <p>Please advise.</p>
