基于大小的log4j.xml滚动Appender [英] log4j.xml Rolling Appender based on size

问题描述

请在下面的我的log4.xml配置中找到滚动文件添加程序

Please find below my log4.xml configuration for rolling file appender

问题是InstrumentationAppender，debugAppender和errorAppender由上述类别中的com.practice pakaage引用.在所有附加程序中，maxFileSize为100kb并已为Test.log文件配置.大小为100kb后，问题Test.log文件不会翻转.所有日志仅被附加到相同的Test.log文件中.如何根据尺寸配置RollingAppender?

The issue is instrumentationAppender,debugAppender and errorAppender are refered by com.practice pakaage as defined in above category. In all the appenders maxFileSize is 100kb and configured for Test.log file. The issue Test.log file does not get rollover after 100kb of size. All logs just get appended to same Test.log file. How do configure RollingAppender based on size?

预先感谢您的帮助.

推荐答案

# Set the maximum file size before rollover
log4j.appender.FILE.MaxFileSize=100KB

# Set the the backup index
log4j.appender.FILE.MaxBackupIndex=2

如果您设置了该选项，它将使备份文件保持在该属性中所提到的位置.

If you set it will be keeping backup files upto what ever you mentioned in that property.
