Answer 1

Your root looger defines debug logging for all components. You should change it to warn (so you still see warnings) and add an extra logger for your own components:

<logger name="com.xxx.mycomponent">
  <level value="trace"/>

  <!-- appenders ... -->

</logger>

<root>
    <priority value="warn" />
    <appender-ref ref="console" />
    <appender-ref ref="dailyrollinglogfile" />
</root>
