i have create a config file for log4cplus and its works but MaxFileSize don't do anything so my files keep growing without taking in considaration my limit . this is my code :

### logs.properties

# root logger

log4cplus.rootLogger=INFO, Main

# specific logger

log4cplus.logger.myloggerINFO, Main
log4cplus.additivity.mylogger=false

# appender that automatically rolls files

log4cplus.appender.Main=log4cplus::DailyRollingFileAppender
log4cplus.appender.Main.Schedule=DAILY
log4cplus.appender.Main.File=mylogs.log
log4cplus.appender.Main.Append=true
log4cplus.appender.Main.MaxBackupIndex=100
log4cplus.appender.Main.MaxFileSize=100KB
log4cplus.appender.Main.layout=log4cplus::PatternLayout
log4cplus.appender.Main.layout.ConversionPattern=%D | %-5.5p | %-20.20c | %m|%n

log4cplus.logger.myLoggerName=DEBUG, R2
log4cplus.appender.R2=log4cplus::RollingFileAppender
log4cplus.appender.R2.File=logs/webaccess.log
log4cplus.appender.R2.Append=true
log4cplus.appender.R2.MaxBackupIndex=5
log4cplus.appender.R2.MaxFileSize=5KB 
log4cplus.appender.R2.layout=log4cplus::PatternLayout
log4cplus.appender.R2.layout.ConversionPattern=%D | %-5.5p | %-20.20c | %m|%n

this is the example of list of files i get :

webaccess.log | 7kb even if max=5
mylogs.log    | 0
mylogs.log.2012-11-26 | 1k
mylogs.log.2012-11-26.1   |1k
...
mylogs.log.2012-11-26.45  | 1k 
he create new files even if max=100k

so if you see anything wrong please tell me thanks

Log4cplus' DailyRollingFileAppender does not observe MaxFileSize property. At the moment either you choose rolling log files by time or by size, you cannot have both at the same time.

EDIT 1:

The appender R2 does not work because there is a lower bound for the allowed MaxFileSize value: const long MINIMUM_ROLLING_LOG_SIZE = 200*1024L; This is 200 KiB. It in the log4cplus source from the start (or really long) and I have never felt a need to remove the limit.

    is there any method to have one log per day not par execution.i don't like to have many of them (1ko !) – Amine Nov 26 '12 at 15:04
  • IIRC, no, there is no way to have just one log per day instead of one per execution with DailyRollingFileAppender. – wilx Nov 26 '12 at 15:06
  • i remark that the logs are generated after i close the application .so if i keep the application working i will have nothing .i have tested with schedule "MINUTELY" ,i run my app for example at 16h41 and i close it at 16h50 -> i get only one file mylogs.log.2012-11-26-16-41 – Amine Nov 26 '12 at 16:48
