Description

Team,

We are using Apache log4j 1.2.x we are able to generate Multiple log files based on package.

As we planned to upgrade from 1.2.x to 2.17.0 we are not able to generate Multiple log files based on package.

Assume our packages are

1.com.application.test.pack1

2.com.application.test.pack2

As per below configuration we could get all the logs into single log file.

    logger.app.name = com.application.test

We expect to log all the logs related to com.application.test.pack1 should be pack1.log;   same way com.application.test.pack2 should be pack2.log, We tried multiple options and also referred official documentation site https://logging.apache.org/log4j/2.x/manual/appenders.html. However we don't find any reference based on our need. 

Below is the log4j2.properties. Same you can find in the attachment section.

status = warn

appender.console.type = Console
appender.console.name = LogToConsole
appender.console.layout.type = PatternLayout
appender.console.layout.pattern =  %d{yyyy-MM-dd HH:mm:ss.SSS} (%t) %-5level [%logger\{36}.%M:%L] - %msg%n

1. Rotate log file
   appender.rolling.type = RollingFile
   appender.rolling.name = LogToRollingFile
   appender.rolling.fileName = logs/app.log
   appender.rolling.filePattern = logs/$${date:yyyy-MM}/app-%d{MM-dd-yyyy}-%i.log.gz
   appender.rolling.layout.type = PatternLayout
   appender.rolling.layout.pattern = %d{yyyy-MM-dd HH:mm:ss.SSS} (%t) %-5level [%logger\{36}.%M:%L] - %msg%n
   appender.rolling.policies.type = Policies
   appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
   appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
   appender.rolling.policies.size.size=10MB
   appender.rolling.strategy.type = DefaultRolloverStrategy
   appender.rolling.strategy.max = 10

1. Log to console and rolling file
   logger.app.name = com.application.test
   logger.app.level = debug
   logger.app.additivity = false
   logger.app.appenderRef.rolling.ref = LogToRollingFile
   logger.app.appenderRef.console.ref = LogToConsole

rootLogger.level = info
rootLogger.appenderRef.stdout.ref = LogToConsole
