问题描述

我有我的应用程序，该应用程序在 log4j 属性文件中完成.基于大小的滚动不适用于此应用程序. 文件不会在5 MB处滚动，并且该应用程序会继续记录并在GB中制作.在一项运行中，生成了大约6 MB的日志.该应用程序每天多次运行.

有人可以帮助指出我在哪里做错吗?

尝试将单元添加到您的尺寸

MaxFileSize=5242880KB

其他推荐答案

我可以看到您正在使用LO4J Companion Extras. 请确保您正在使用最新的log4j.jar(版本1.2.17为我工作，我遇到了1.2.14版的问题).

我写了简单的测试应用程序来重现您的问题:

package com.ibm.hmel.hwmmphdya;
import org.apache.log4j.Logger;

public class Roller {

    private Logger logger = Logger.getLogger(Roller.class);
    private final String FAKE_LOG_LINE = "12345678901234567890123456789012345678901234567890";

    public static void main(String[] args) {
        Roller roller = new Roller();
        roller.logStuff();
    }

    private void logStuff() {
        for (;;) { // ugly loop
            logger.info(FAKE_LOG_LINE);
        }
    }
}

并在classpath中放置log4j.properties:

log4j.category.com.ibm.hmel.hwmmphdya=INFO, Roller
log4j.additivity.com.ibm.hmel.hwmmphdya=false
log4j.appender.Roller=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.Roller.File=D:/FIH/SAMPLE_APP_01.log
log4j.appender.Roller.layout=org.apache.log4j.PatternLayout
log4j.appender.Roller.layout.ConversionPattern=%-21d{dd-MMM-yyyy HH:mm:ss} [%t] %-5p %c %x - %m%n
log4j.appender.Roller.RollingPolicy=org.apache.log4j.rolling.FixedWindowRollingPolicy
log4j.appender.Roller.RollingPolicy.FileNamePattern=D:/FIH/SAMPLE_APP_01.log.%i.zip 
log4j.appender.Roller.RollingPolicy.MinIndex=1 
log4j.appender.Roller.RollingPolicy.MaxIndex=10 
log4j.appender.Roller.TriggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy
log4j.appender.Roller.TriggeringPolicy.MaxFileSize=5242880

我认为我的结果还可以，这些是我的日志输出目录的内容:

2013-02-27  09:30    <DIR>          .
2013-02-27  09:30    <DIR>          ..
2013-02-27  09:30         4 440 720 SAMPLE_APP_01.log
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.1.zip
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.2.zip
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.3.zip
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.4.zip
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.5.zip

文件大小" 5 242 920"或多或少是配置的.

您可以通过提供-Dlog4j.debug系统属性来进一步解决案件.

更新: 您可能需要确保classPath中存在伴侣Extras lib(apache-log4j-extras-1.1.jar).

问题描述

I have my application for which the below entry is done in Log4j properties file.Size based rolling is not working for this application. File does not rollover at 5 MB and the application keeps on logging and making it in GB. In one run approximately 6 MB of log is generated.The application runs multiple times a day.

Can someone help in pointing out where I am doing a mistake?

Following works for me 

log4j.rootLogger=TRACE, Roller

log4j.appender.Roller=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.Roller.RollingPolicy=org.apache.log4j.rolling.FixedWindowRollingPolicy

log4j.appender.Roller.layout=org.apache.log4j.PatternLayout
log4j.appender.Roller.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

Try adding a unit to your size

MaxFileSize=5242880KB

其他推荐答案

As i can see you're using lo4j companion extras. Please ensure you're using latest log4j.jar (version 1.2.17 worked for me and I've encountered problems with version 1.2.14).

I wrote simple test app to reproduce your problem:

package com.ibm.hmel.hwmmphdya;
import org.apache.log4j.Logger;

public class Roller {

    private Logger logger = Logger.getLogger(Roller.class);
    private final String FAKE_LOG_LINE = "12345678901234567890123456789012345678901234567890";

    public static void main(String[] args) {
        Roller roller = new Roller();
        roller.logStuff();
    }

    private void logStuff() {
        for (;;) { // ugly loop
            logger.info(FAKE_LOG_LINE);
        }
    }
}

and placed following log4j.properties in classpath:

log4j.category.com.ibm.hmel.hwmmphdya=INFO, Roller
log4j.additivity.com.ibm.hmel.hwmmphdya=false
log4j.appender.Roller=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.Roller.File=D:/FIH/SAMPLE_APP_01.log
log4j.appender.Roller.layout=org.apache.log4j.PatternLayout
log4j.appender.Roller.layout.ConversionPattern=%-21d{dd-MMM-yyyy HH:mm:ss} [%t] %-5p %c %x - %m%n
log4j.appender.Roller.RollingPolicy=org.apache.log4j.rolling.FixedWindowRollingPolicy
log4j.appender.Roller.RollingPolicy.FileNamePattern=D:/FIH/SAMPLE_APP_01.log.%i.zip 
log4j.appender.Roller.RollingPolicy.MinIndex=1 
log4j.appender.Roller.RollingPolicy.MaxIndex=10 
log4j.appender.Roller.TriggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy
log4j.appender.Roller.TriggeringPolicy.MaxFileSize=5242880

My results are OK i think, theese are contents of my log output directory:

2013-02-27  09:30    <DIR>          .
2013-02-27  09:30    <DIR>          ..
2013-02-27  09:30         4 440 720 SAMPLE_APP_01.log
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.1.zip
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.2.zip
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.3.zip
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.4.zip
2013-02-27  09:30         5 242 920 SAMPLE_APP_01.log.5.zip

File size "5 242 920" is more or less what was configured.

You can troubleshoot your case further by providing -Dlog4j.debug system property.

UPDATE: You may want to ensure companion extras lib (apache-log4j-extras-1.1.jar) is present in classpath.
