Hello we have applications that write to a file called xfiles.log. Log4j does a daily rename to xfiles.log.date, for example xfiles.log.2009-04-12. I would like to remove the '.log' and just have a date extension. For example the new file would be xfiles.2009-04-12. Below is our current log4j setup. Thanks
log4j.rootCategory=INFO, DAILY
log4j.logger.org.springframework=WARN
log4j.appender.DAILY=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DAILY.file=${LOGDIR}/xfiles.log
log4j.appender.DAILY.datePattern='.'yyyy-MM-dd
log4j.appender.DAILY.append=true
log4j.appender.DAILY.layout=org.apache.log4j.PatternLayout
log4j.appender.DAILY.layout.ConversionPattern=%d{ISO8601} %-5p [%t] %c %m %n

I see the following properties set in my application log properties. What does ${hadoop.log.dir}/${hadoop.log.file} mean? How will I come up with the log files destination looking aat these properties?
I think you can
echo ${hadoop.log.dir} or echo ${hadoop.log.file} to see the path of the directory.
I have a problem where log4j is not logging to one of my files and i'm not sure why. I have some code that runs scripts, the scripts can add logging which is logged to a file using log4j, I am trying to create an appender that only logs for a particular script.
log4j.logger.com.my.class=INFO, JS_LOG
log4j.appender.JS_LOG.layout=org.apache.log4j.PatternLayout
log4j.appender.JS_LOG.Encoding=UTF-8
log4j.appender.JS_LOG.File=${log.outputdir}/js_service.log
log4j.appender.JS_LOG.MaxFileSize=2MB
log4j.appender.JS_LOG.MaxBackupIndex=10
log4j.appender.JS_LOG.Append=true
log4j.appender.JS_LOG=org.apache.log4j.RollingFileAppender
log4j.appender.JS_LOG.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n
the above appender works and i get this in my log file
2012-04-18 11:25:52,043 [<MD> Inc Msg Dispatch-1 New] INFO com.my.class.file:/myfile - info
when the script logs something it logs to a logger of the form
com.my.class.file:/myfile this appears in the log using the above config in my log4j.properties file.
if I change the above to:
log4j.logger.com.my.class.file:/myfile=INFO, JS_LOG
log4j.appender.JS_LOG.layout=org.apache.log4j.PatternLayout
log4j.appender.JS_LOG.Encoding=UTF-8
log4j.appender.JS_LOG.File=${log.outputdir}/js_service.log
log4j.appender.JS_LOG.MaxFileSize=2MB
log4j.appender.JS_LOG.MaxBackupIndex=10
log4j.appender.JS_LOG.Append=true
log4j.appender.JS_LOG=org.apache.log4j.RollingFileAppender
log4j.appender.JS_LOG.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n
nothing is logged to the file. I would have thought this should work? I retrieve the file
I managed to solve this problem, its something to do with the file: in my log4j.properties I changed the appender to file_ then in my code I do some manipulation to the file url to make it match the appender.
I have to create new file for each level like:
fatel.log for only FATAL
error.log for only ERROR
warn.log for only WARN etc.
how can i achieve this thing in changing this properties file.
Here is my log4j.properties file:
FILE
# level : OFF,FATAL,ERROR,WARN,INFO,DEBUG,ALL
log4j.rootLogger=DEBUG,CONSOLE,A1
log4j.addivity.org.apache=true
# for console
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=INFO
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.Encoding=UTF-8
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=[INFO] %d - %c -%-4r [%t] %-5p %c %x - %m%n
# A1
log4j.appender.A1=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A1.File=C:/hibernateSqlite.log
log4j.appender.A1.Encoding=UTF-8
log4j.appender.A1.Threshold=DEBUG
log4j.appender.A1.DatePattern='.'yyyy-MM-dd
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L : %m%n
Though I've never done it, I guess it will be something like:
log4j.appender.AppDebug.filter.DebugFilter=org.apache.log4j.varia.LevelMatchFilter
log4j.appender.AppDebug.filter.DebugFilter.acceptOnMatch=true
log4j.appender.AppDebug.filter.DebugFilter.levelToMatch=DEBUG
The type of the AppDebug appender could be DailyRollingFileAppender, as in your case, with the remaining configuration options along.
In my application , Multiple threads log the data in the same file .if the file size exceeds the limit , then i have to delete the particular record in file and move every contents upwards.
can I do this in Log4cxx?if so ,reply your thoughts..
Thanks..
This sample will solve your problem :
log4j.rootLogger=debug, stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log
log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex = 0
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
This will override the file contents in the same file.
