I have tested RFA appender for Falcon logs . Please make below changes in Falcon log4j.xml .(Example - Metric logs)

     <appender name="METRIC" class="org.apache.log4j.RollingFileAppender">
        <param name="File" value="${falcon.log.dir}/${falcon.app.type}.metric.log"/>
        <param name="Append" value="true"/>
        <param name="Threshold" value="debug"/>
        <param name="MaxBackupIndex" value="10"/>
         <param name="MaxFileSize" value="2048"/>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d %m%n"/>
        </layout>
    </appender>

You can set MaxBackupIndex(Number of files) and MaxFileSize(Size in Bytes) as per you environment.

Also, You can set it similarly for other logs like audit logs etc.
