title: Disable DEBUG level logs in logback.xml keeping INFO and ERROR level logs
body: <p>My logback.xml looks like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;configuration&gt;
    &lt;jmxConfigurator/&gt;
    &lt;statusListener class="ch.qos.logback.core.status.NopStatusListener"/&gt;
  
    &lt;property name="LOG_DIR" value="/tmp/logs"/&gt;
    &lt;springProperty name="appName" source="spring.application.name"/&gt;
    &lt;appender class="ch.qos.logback.core.ConsoleAppender" name="STDOUT"&gt;
      &lt;layout class="ch.qos.logback.classic.PatternLayout"&gt;
        &lt;Pattern&gt;
          some pattern
        &lt;/Pattern&gt;
      &lt;/layout&gt;
    &lt;/appender&gt;
  
    &lt;logger additivity="false" level="DEBUG"
      name="xyz"&gt;
      &lt;appender-ref ref="STDOUT"/&gt;
    &lt;/logger&gt;
    &lt;root level="ERROR"&gt;
      &lt;appender-ref ref="STDOUT"/&gt;
    &lt;/root&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>I am trying to disable DEBUG logs from the entire application and couldn't find a way to do so. I want to print INFO, ERROR level logs.</p>
