log4j not zipping log files - java

I am not able to understand what I am missing here. Below is my log4j.properties
# Root logger option
log4j.rootLogger=INFO, file
# Redirect log messages to a log file
log4j.appender.file=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.file.rollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.file.rollingPolicy.ActiveFileName=${catalina.home}/logs/broker.log
log4j.appender.file.rollingPolicy.FileNamePattern=${catalina.home}/logs/broker-.%d{yyyyMMdd-HH}.log.gz
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


you forget to set MaxFileSize,just add the following to your RollingFileAppender configuration and having the filename end in .gz will automagically compress your logfiles:
log4j.appender.file=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.file.rollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.file.rollingPolicy.ActiveFileName=${catalina.home}/logs/broker.log
log4j.appender.file.rollingPolicy.FileNamePattern=${catalina.home}/logs/broker-.%d{yyyyMMdd-HH}.log.gz
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.MaxFileSize=10M
log4j.appender.file.MaxBackupIndex=3
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
hope that helped

can't able to implement log4j for JBOSS EAP 7 using java?

i have an application, i have applied log4j, but i can't able to create log file inside jboss application.
when i put absolute path of system in log4j.appender.file.File= D:/log/application.log it was working fine but when i put log4j.appender.file.File= ${jboss.server.home.dir}/log/application.log it is not working.
# Root logger option
log4j.rootLogger=DEBUG, stdout, file
# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
#log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File= ${jboss.server.home.dir}/log/application.log
log4j.appender.file.MaxFileSize=5KB
log4j.appender.file.MaxBackupIndex=10
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

try using $JBOSS_HOME instead of ${jboss.server.home.dir}.. so it becomes
log4j.appender.file.File= ${JBOSS_HOME }/log/application.log

correct setting for log4j to redirect logs(warning,info,error) to file

i am using log4j for logging my log4j.properties file is:
# Root logger option
log4j.rootLogger=INFO, stdout, file
# Redirect log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
#outputs to Tomcat home
log4j.appender.file.File= D:/log_file.log
log4j.appender.file.MaxFileSize=5MB

log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
its not working for warning Please help thanks

Please see this:
log4j.rootLogger=INFO, file
log4j.rootLogger=DEBUG, file
log4j.rootLogger=WARNING, file
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out

Log4j's RollingFileAppender doesn't create a file

I have a Spring Boot application which uses Log4j. I've set up RollingFileAppender and ConsoleAppender. The second one works fine, but RollingFile Appender doesn't create a file.
Here's a file with properties:
log4j.rootLogger=DEBUG, stdout, file
# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=log4j-application.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
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
Any ideas will be very appreciated.

Use this configurarion
log4j.rootLogger=DEBUG, consoleAppender, fileAppender
log4j.appender.consoleAppender=org.apache.log4j.ConsoleAppender
log4j.appender.consoleAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.consoleAppender.layout.ConversionPattern=[%t] %-5p %c %x - %m%n
log4j.appender.fileAppender=org.apache.log4j.RollingFileAppender
log4j.appender.fileAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.fileAppender.layout.ConversionPattern=[%t] %-5p %c %x - %m%n
log4j.appender.fileAppender.File=demoApplication.log
For more info visit this link http://howtodoinjava.com/2013/04/08/how-to-configure-log4j-using-properties-file/

Or maybe you can try the following for daily-logging
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.File=logfile.log
log4j.appender.logfile.Threshold = INFO
log4j.appender.logfile.DatePattern='_'yyyyMMdd'.log'
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

Log4j.properties not producing timestamp

I am new to using Apache's Log4J and am trying to be able to produce a timestamp with every bit of Logging it does on a program I am building. However, when I run the program in Eclipse, Log4j is only producing the message I have in my code (without the timestamp). I am thinking it has something to do with how I have my Log4j.properties file set up:
log4j.rootLogger=INFO, file
log4j.rootLogger=DEBUG, file
log4j.rootLogger=WARNING, file
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/home/ryan/workspace/wheel/src/main/resources/logging/application.log
log4j.appender.file.MaxFileSize=20MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
Whenever I try something like this in my code:
logger.info("Connecting to Server")
This is what I see in my log file:
Connecting to Server
Does anyone have any suggestions?

this is incorrect
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
it should be
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

How to write file append property file in log4j

Here is my log4j property file I am using console appender but i need to use file appender could anybody expline me how to write that and where to find that file after run my application....
# Root logger option
log4j.rootLogger=INFO, file
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=${catalina.base}/logs/mylog.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
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

Here is the standard properties file which I use for my project.. this will print logging output on console as well as in a file.
# Root logger option
log4j.rootLogger=INFO, file, stdout
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\springtest.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
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
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

For appending to a file, follow the below properties
# Root logger option
log4j.rootLogger=INFO, file
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\loging.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
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
Visit this link for more details
to place in tomcat directory:
log4j.appender.file.File=${catalina.base}/logs/mylog.log
