Log4j appender size
提问by Muhammad Imran Tariq
My appender size was set to MB in log4j appneder but when I changed it to KB's It did not work. Can I set log4j appender size in KB's.
我的 appender 大小在 log4j appneder 中设置为 MB，但是当我将其更改为 KB 时，它不起作用。我可以以 KB 为单位设置 log4j appender 大小吗？

log4j.appender.processAppender.MaxFileSize=20KB
If yes then is there need to add another property? My file looks like:
如果是，那么是否需要添加另一个属性？我的文件看起来像：
log4j.rootLogger=DEBUG,FileAppender
log4j.logger.process=debug, processAppender
log4j.appender.processAppender=org.apache.log4j.RollingFileAppender
log4j.appender.processAppender.File=D:/logs/process.log
log4j.appender.processAppender.Append=true
log4j.appender.processAppender.MaxFileSize=20KB
log4j.appender.processAppender.MaxBackupIndex=3
log4j.appender.processAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.processAppender.layout.ConversionPattern=%d %-5p - %m%n

I've used below code
我使用了下面的代码
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=AgentWorkstation.log
log4j.appender.file.Append=true
log4j.appender.A1.MaxFileSize=10KB
log4j.appender.A2.MaxBackupIndex=3
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss,SSS}
%-5p (%C{1}:%L) - %m\n
It worked perfectly for me
它非常适合我

Set the maximum size that the output file is allowed to reach before being rolled over to backup files. In configuration files, the MaxFileSize option takes an long integer in the range 0 - 2^63. You can specify the value with the suffixes "KB", "MB" or "GB" so that the integer is interpreted being expressed respectively in kilobytes, megabytes or gigabytes. For example, the value "10KB" will be interpreted as 10240.
设置输出文件在滚动到备份文件之前允许达到的最大大小。在配置文件中，MaxFileSize 选项采用 0 - 2^63 范围内的长整数。您可以指定带有后缀“KB”、“MB”或“GB”的值，以便将整数解释为分别以千字节、兆字节或千兆字节表示。例如，值“10KB”将被解释为 10240。

Yes you can set KB as a unit and your configuration seems like correct. This is the explanation from the IBM's webpage.
是的，您可以将 KB 设置为一个单位，并且您的配置似乎是正确的。这是来自IBM 网页的解释。
Specifies the maximum file size that the log file is allowed to take up on disk.
Default size is 100 MB.
Uses the following format:
log4j.appender.S1.MaxFileSize=SizeUnits
where:
Size is the numeric value for the file size. Units can be KB, MB, or GB. For example, to limit the log file size to 10 MB, enter the following:
log4j.appender.S1.MaxFileSize=10 MB
If the MaxBackupIndex parameter is set to 1 or greater, then the logging process automatically creates a backup file when the log file reaches the MaxFileSize. The total number of backup files is determined by MaxBackupIndex option.
指定允许日志文件在磁盘上占用的最大文件大小。
默认大小为 100 MB。
使用以下格式：
log4j.appender.S1.MaxFileSize=SizeUnits
在哪里：
大小是文件大小的数值。单位可以是 KB、MB 或 GB。例如，要将日志文件大小限制为 10 MB，请输入以下内容：
log4j.appender.S1.MaxFileSize=10 MB
如果 MaxBackupIndex 参数设置为 1 或更大，那么当日志文件达到 MaxFileSize 时，日志记录过程会自动创建一个备份文件。备份文件的总数由 MaxBackupIndex 选项决定。

You should change 3 property under the Appender.
您应该更改 Appender 下的 3 个属性。
log4j.appender.CARBON_LOGFILE.Append=true
log4j.appender.CARBON_LOGFILE.MaxFileSize=10MB
log4j.appender.CARBON_LOGFILE.MaxBackupIndex=20
