Answer 1

Make sure your configuration has below appender...We have used log4j.xml so i am adding from xml

<appender name="console" class="org.apache.log4j.ConsoleAppender">
    <param name="Target" value="System.out" />
    <param name="Threshold" value="info" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%-5p: %c - %m%n" />
    </layout>
</appender>

<appender name="logfile" class="org.apache.log4j.RollingFileAppender">
    <param name="File" value="log/dcm_migration.log" />
    <param name="Append" value="false" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d  %-5p  [%c{1}] %m %n" />
    </layout>
</appender>

Answer 2

log4j.appender.Stdout.threshold=info

Should be:

log4j.appender.Stdout.threshold=debug

You just set the console threshold to be info, so you're not getting debug level logs.

Be aware you also set the RollingFileAppender threshold to info as @Stephen C commented.
