Hong, Re-reading your message…you will need to change the configuration of the log4j/worker.xml file so that components/loggers under your package name (and those that you are interested go into a separate appender.
So you’ll have to add a <Logger name=“org.maohong.tech”> and a <Logger name=“com.my.thirdparty.package”> etc etc. and then create Appenders for Files that are separate from those already declared (e.g. A1). As an alternative approach have you tried configuring Log4J2 with your own custom log4j2.xml from within your topology?
