I have my log4j.properties file as -
# Root logger option
log4j.rootLogger=WARN, file
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/tmp/logging.log
log4j.appender.file.MaxFileSize=10MB
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
Problem is, log messages are also getting printed on console. How can I disable that? I have read some of the posts here on stackoverflow but other users were facing issues because they defined the consoleAppender into their file but I haven't defined it in my log4j.properties file and still it displays it on console.
Please help.
Try doing additivity false. like below in your property file.
log4j.additivity=false
log4j.rootLogger=ERROR, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d %5p %c (%F:%L) - %m%n
#hide the Log4jMemoryAppender from console
log4j.logger.nz.ac.massey.cs.sdc.log4jassignment.s06005586.MemoryAppender= ERROR, MEMORY_APPENDER
log4j.appender.MEMORY_APPENDER=nz.ac.massey.cs.sdc.log4jassignment.s06005586.MemoryAppender.Log4jMemoryAppender
log4j.additivity.rootLogger = false
log4j.additivity.console = false
log4j.additivity.MEMORY_APPENDER=false

I have implemented the log4j with following properties.
# Root logger option
log4j.rootLogger=DEBUG, stdout, file
# Redirect log messages to consol
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=/home/../log4j-application.log

It is working on localhost where in server side it log nothing . I guess above are the general configuration. Is there something i am missing here? I use TomEE on both client and server.Also i used the logger as following. It also does not write in local file. Only logger seems to work on client.
private static final Logger LOGGER = Logger.getLogger(MyClass.class);
I think problem with this line
log4j.appender.file.File=/home/../log4j-application.log
Please use (if you have a log folder)
log4j.appender.file.File=log/log4j-application.log
I am using probe along with tomcat. My application which is deployed in tomcat 8.5 use log4j for its logging.
This is Log4j.properties configuration :
# Root logger option
log4j.rootLogger=DEBUG, file
log4j.logger.org.hibernate.SQL = DEBUG, file
log4j.logger.org.hibernate.type = TRACE, file
# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=${catalina.base}/logs/my-app.log
log4j.appender.file.Append=true
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.appender.file.DatePattern='.'yyyy-MM-dd
log4j.appender.file.rollingPolicy.ActiveFileName=${catalina.base}/logs/my-app.log
log4j.appender.file.rollingPolicy.FileNamePattern=${catalina.base}/logs/archive/my-app-%d{yyyy-MM-dd}.log.gz
Everything is fine and i could fine my logs, but when the server restart i lost everything.
It seams like probe delete the log file after reboot
Am i missing something in the configuration on my application or even in the prob side?

log4j.rootLogger=DEBUG, stdout, file

can you check above code?
put all properties in your log4j properties file
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
I'm getting two warnings.
log4j:WARN No appenders could be found for logger (com.org.Resolver).
log4j:WARN Please initialize the log4j system properly.
How to resolve it?
My java class name Resolver.java
In java class i'm calling
private static Log log = LogFactory.getLog(Resolver.class);
You need to put log4j.properties or log4j.xml in your classpath. So, create file name log4j.properties and replace the content with below:
# Root logger option
log4j.rootLogger=INFO, 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
#. represents the current folder (usually the project root folder)
log4j.appender.file.File=./logging.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
I am using log4j for logging , my requirement is to log all the logs from package
pkg1 (except pkg1.pkg2) to pkg1.log
and pkg1.pkg2 (a sub package of the above package) to pkg2.log
is this possible ? I know i can achieve it through custom appenders but is there a way I can do it through configurations.
I am using the below properties file. Here the problem is PKG1.log contains logs from PKG2 also.
# Root logger option
log4j.rootLogger=WARN, CONSOLE
# Direct log messages to a log file
log4j.logger.com.pkg1=DEBUG, PKG1 log4j.appender.PKG1=org.apache.log4j.RollingFileAppender
log4j.appender.PKG1.File=logs/PKG1.log
log4j.appender.PKG1.MaxFileSize=1MB
log4j.appender.PKG1.MaxBackupIndex=1
log4j.appender.PKG1.layout=org.apache.log4j.PatternLayout
log4j.appender.PKG1.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.logger.com.pkg1.pkg2=DEBUG, PKG2
log4j.appender.PKG2=org.apache.log4j.RollingFileAppender
log4j.appender.PKG2.File=logs/PKG2.log
log4j.appender.PKG2.MaxFileSize=1MB
log4j.appender.PKG2.MaxBackupIndex=1
log4j.appender.PKG2.layout=org.apache.log4j.PatternLayout
log4j.appender.PKG2.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Direct log messages to CONSOLE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
You can stop PKG2's logs from reaching it's ancestor's appenders by disabling the additivity flag in the configuration:
log4j.appender.PKG2.additivity=false
