How to control log file with daily rolling and max file size by log4j?

Question

I would like to create log file that can be rolled at the beginning of the next day or if it\'s reached to specified file size and log file must be contained inside date folder.

Answer 1

Daily works for me with xml in question only transformed into log4j.properties equivalent to roll over after 100KB (for testing purposes):

# Root logger option
log4j.rootLogger=INFO, file

# Direct log messages to a file
log4j.appender.file=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.file.RollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.file.RollingPolicy.FileNamePattern=/path/to/logs/%d{yyyyMMdd}/myLog_%d{yyyyMMddHH}.log
log4j.appender.file.TriggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy
log4j.appender.file.TriggeringPolicy.maxFileSize=100000
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.appender.file.Append=true

This will create a timestamped directory (one directory per day - optional) with logs with the following format (one per hour for testing purposes - change FileNamePattern to suit your needs):

myCompanyLog_201602031030.log

myCompanyLog_201602031130.log
