log4j file appender

Hi,

I am using log4j for logging. I am working on a huge application and there would be lots of logs each day. Thereby it is requried that the log files be stored and renamed each day. The date is appended to the log file and that day's log file is stored. The logs start writing afresh each day. The problem here is that at times the application simply starts logging to the previous day's log file, for a while, and then starts writing back to the current day's file again. I am not able to figure out what goes wrong and when. The application is running on weblogic. Can anybody please help? The log4j properties file is here....

Hello Rashshuu.

I just experienced this exact same scenario today (2004/08/27) and

I am similarly at a loss to explain it. A quick scan through the Log4j

bug database did not turn up an exact match (but it could be buried

somewhere in there).

If I find anything further I will let you know. Try checking

http://logging.apache.org/site/bugreport.html yourself and see if

you can find anything indicating this is an open problem. If not

one of us should open up a bug report.

Good luck.

Hello,

i have a problem with DailyRollingFileAppender : it not tiny every wheel as I have indicated. The code is below:

log4j.logger.it.na.its.csinfo.presentation = DEBUG, A1

log4j.appender.A1 = org.apache.log4j.DailyRollingFileAppender

log4j.appender.A1.File = test/it/na/its/csinfo/presentation/CsInfoLog.log

log4j.appender.A1.DailyRollingFileAppender.DatePattern = '.'yyyy-MM-dd-HH-mm

log4j.appender.A1.layout = org.apache.log4j.PatternLayout

log4j.appender.A1.layout.ConversionPattern = %d [%t] %-5p %c %M - %m%n

May you help me?

Thanks

Hi guys!I just had the exact same probleme with log4j 1.2.9. Somebody got a solution for this? I would be really useful because right now we do have the log for the current day but all the previous day are lost because log4j is rewriting in them.Thanks!

Hi, Onirike ,

I met exactly the same problem as yours. How did you solve it?

This is my configuration file.

log4j.logger.A1=INFO, A1

log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender

log4j.appender.A1.File=/usr/java/jboss-4.0.2/server/default/log/tcmlog/httpproxy_access.log

log4j.appender.A1.DatePattern='.'yyyy-MM-dd

log4j.appender.A1.Append=false

log4j.appender.A1.layout=org.apache.log4j.PatternLayout

log4j.appender.A1.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %p %m%n

Thank you!

I found from the log4j 1.3 API javadoc, the DailyRollingFileAppender is deprecated. They use the RollingFileAppender instead and give one sample .

Hope it helps!

<!DOCTYPE log4j:configuration>

<log4j:configuration debug="true">

<appender name="ROLL" class="org.apache.log4j.rolling.RollingFileAppender">
