Log4j2 AsyncLogger with rolling file appender not showing file line number

Question

Im using log4j2 with following dependencies:

<!-- LOG4J2 -->
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-api</artifactId>
        <version>2.0-rc1</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
        <version>2.0-rc1</version>
    </dependency>
    <dependency>
        <groupId>com.lmax</groupId>
        <artifactId>disruptor</artifactId>
        <version>3.0.1</version>
    </dependency>

Log4j2.xml content:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="OFF">

<Appenders>
    <Console name="CONSOLE" target="SYSTEM_OUT">
        <PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n" />
    </Console>

    <!-- Generate rolling log for router with per hour interval policy -->
    <RollingFile name="ProcessorRollingFile" fileName="D:/ocsprocessor.log"
        filePattern="D:/ocsprocessor.log.%d{MM-dd-yyyy}-%i.log">
         <PatternLayout>
      <pattern>%d{ISO8601} [%t] %p %c %L - %m%n</pattern>
  </PatternLayout>
        <Policies>
            <TimeBasedTriggeringPolicy interval="1" />
        </Policies>
        <DefaultRolloverStrategy max="24" />
    </RollingFile>



    <!-- Register Async appender -->
    <Async name="AsyncRollingFile">
        <AppenderRef ref="ProcessorRollingFile" />
    </Async>
</Appenders>

<Loggers>
    <AsyncLogger name="com.tritronik.logger.log4j2" level="error"
        additivity="false">
        <AppenderRef ref="AsyncRollingFile" />
    </AsyncLogger>


</Loggers>
</Configuration>

Turn out that everything went fine except the log doesn't show Line number of throwed logger (the %L in pattern).

I googled and found out that for async logger and rolling file appender, there is no one mentioned using %L, so how can i achieved it then? Or is it doesn't support %L?

Edit: I have tried added includeLocation="true", but still same results

Thanks

Answer 1

First, remove the Async appender, and point the appender-ref of the AsyncLogger to the ProcessorLoggingFile directly. Second, you must add includeLocation="true" on the AsyncLogger.

Having an async appender in addition to an async logger does not help and in this case might be what prevents the includeLocation from working correctly.
