如何清除Log4j 2.3每日滚动文件附加程序的日志

Question

I am currently using log4j2 to write logs for my web application. I have configured a rolling file appender to roll over at midnight each night.

My log4j2.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %c{36} - %msg%n"/>
        </Console>
        <RollingFile
            name="ApplicationLog"
            fileName="${sys:catalina.base}/logs/application.log"
            filePattern="${sys:catalina.base}/logs/application %d{yyyy-MM-dd}.log">
              <PatternLayout>
                  <Pattern>%d{HH:mm:ss.SSS} [%t] %-5level %c{36} %l: %msg%n</Pattern>
              </PatternLayout>
              <Policies>
                  <TimeBasedTriggeringPolicy interval="1" modulate="true"/>
              </Policies>
              <DefaultRolloverStrategy/>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="my.package" level="info" additivity="false">
            <AppenderRef ref="ApplicationLog"/>
        </Logger>
        <Logger name="my.test.package" level="debug" additivity="false">
            <AppenderRef ref="Console"/>
        </Logger>
        <Root level="error">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

Currently, this writes to a log called application.log, then at midnight the current application.log file is copied to application yyyy-MM-dd.log (the date in the file name is replaced properly), and logging continues on the next day in application.log.

What I would like to happen is for application.log to be cleared before starting the new day. At the moment, this isn't happening, and as a result my log sizes are ever-increasing. My day 1 log contains all logging from day 1, but my day 2 log contains logging from day 1 and day 2, and so on.

How can I reset the application.log file once the rollover occurs? According to the Log4j 2.x documentation , a new application.log file should be created, rather than the current file being continued, but this is not the behaviour I'm experiencing.

Any help would be greatly appreciated.

Thanks, Adam

Answer 1

I figured this one out by debugging through the source code as my logs were supposed to roll over.

Apparently, there is an undocumented attribute that can be placed in the RollingFile element called "append", which, when set to false , will write the current log file from the beginning. Unfortunately, the default value for this attribute is true , which causes the current log file to be appended rather than restarted.

So my final log4j2.xml looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %c{36} - %msg%n"/>
        </Console>
        <RollingFile
            name="ApplicationLog"
            fileName="${sys:catalina.base}/logs/application.log"
            filePattern="${sys:catalina.base}/logs/application %d{yyyy-MM-dd}.log"
            append="false">
              <PatternLayout>
                  <Pattern>%d{HH:mm:ss.SSS} [%t] %-5level %c{36} %l: %msg%n</Pattern>
              </PatternLayout>
              <Policies>
                  <TimeBasedTriggeringPolicy interval="1" modulate="true"/>
              </Policies>
              <DefaultRolloverStrategy/>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="my.package" level="info" additivity="false">
            <AppenderRef ref="ApplicationLog"/>
        </Logger>
        <Logger name="my.test.package" level="debug" additivity="false">
            <AppenderRef ref="Console"/>
        </Logger>
        <Root level="error">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>

Hopefully this helps someone else figure out this problem in less than the 3 days that it took me.

EDIT : So it turns out that this attribute is documented here (the first parameter in the table), but it still doesn't make sense to me why appending is the default behaviour. Why would I want my file size to be forever increasing!? Anyway, not the point, just ranting!

Thanks, Adam

Answer 2

Looks like the same issue you are facing.

Check the folder permissions for the log folder and give write permission to it.

chmod 666 logs
