Log4j is not writing the log files to a file but writing to console. I searched through a lot of resources (i think this question already exists) for it but was unable to find a solution.
Log4j version 1.2.17
Below is my log4j configuration:
log4j.rootLogger=INFO, stdout log4j.rootCategory=INFO, stdout , File
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %t
%c{20}:%L - %m%n
log4j.category.org.springframework=ERROR
log4j.category.org.springframework.beans.factory=ERROR
log4j.category.com.mypackage=INFO
log4j.logger.org.springframework=ERROR
log4j.logger.org.hibernate=ERROR
log4j.logger.org.hibernate.persister.entity=ERROR
log4j.appender.File = org.apache.log4j.rolling.RollingFileAppender
log4j.appender.File.File=/tmp/mylog.log
log4j.appender.File.ImmediateFlush=true
log4j.appender.File.threshold=INFO log4j.appender.File.Append=true
log4j.appender.File.MaxFileSize=10MB
log4j.appender.File.MaxBackupIndex=20
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=%d{ABSOLUTE} %5p %t
%c{2}:%L - %m%n log4j.appender.File.rollingPolicy =
org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.File.rollingPolicy.FileNamePattern
=/tmp/mylog%d.log
log4j.appender.File.layout.ConversionPattern=%d{ABSOLUTE} %5p %t
%c{2}:%L - %m%n
I have made sure I have permissions to the directory where i am trying to write to.
Can some one please help me out?
Please make the below mentioned changes to your config file.
log4j.appender.file=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.file.File=/tmp/mylog.log
log4j.appender.file.ImmediateFlush=true
log4j.appender.file.threshold=INFO
log4j.appender.file.Append=true
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=20
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %t %c{2}:%L - %m%n
log4j.appender.file.rollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.file.rollingPolicy.FileNamePattern=/tmp/mylog%d.log
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %t %c{2}:%L - %m%n
Hope this works fine.

I'm trying to have a log output file with a path like .log/ DD-MM-AAAA - Filename.log
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=./logs/%d{yyyy-MM-dd HH:mm:ss} - logTest.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=2
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
Actually it doesn't work. If I remove %d{yyyy-MM-dd HH:mm:ss} the output is : logs/logTest.log
But i need to have the date on my output file name.
What I want is :logs/DD-MM-YYYY - logTest.log
Can you please show me how to do that?
Try below snippet, it will add date to generated log file next day.
# configure the root logger
log4j.rootLogger=INFO, DAILY, stdout
#configure the daily rolling file appender
log4j.appender.DAILY=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DAILY.File=/opt/ZudioFeedbackApplication/log/zudio.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.DAILY.DatePattern='.'yyyy-MM-dd
log4j.appender.DAILY.layout=org.apache.log4j.PatternLayout
log4j.appender.DAILY.layout.conversionPattern=%d{HH:mm} [%p] %c:%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
The Generated log file will be like.
zudio.log (you can change name and path), and next day it will rename itself with zudio.log.2019-11-19. For your requirement try it by changing DatePattern
I tried to implement a levelmatchfilter for a custom loglevel and configure it within a properties file.
Used the template for the chrunchify loglevel for creating mine:
http://crunchify.com/java-how-to-create-your-own-logging-level-in-log4j-configuring-log4j/
Configured my properties file as follwing:
log4j.rootLogger.level=DEBUG
# LOG4J daily rolling log files configuration
log4j.rootLogger=debug, DebugAppender, InfoAppender, ErrorAppender, ChangeAppender
#DebugAppender (Debug)
log4j.appender.DebugAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DebugAppender.File=./log/debug/ngpmt_debug.log
log4j.appender.DebugAppender.DatePattern='.'yyyy-MM-dd
log4j.appender.DebugAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.DebugAppender.layout.ConversionPattern=[%p] %d %c %M - %m%n

I have 3 log-files with different scopes. Additional to that i want a log-file where only CHANGE-Level messages are logged to.
I am trying to send syslog messages from my web application to RSYSLOG and then view them in logAnalyzer.
I manage to see the logs but the following fields are not shown in the main table: Facility, Sevirty, ProcessID. They do appear in the messages, but their columns are empty.
In what format should I send them message so that the logAnalyser will be able to parse it correctly?
I am looking for the right log4j.appender.SYSLOG_LOCAL1.layout.conversionPattern string to place in my log4j.xml file.
Here is my log4j.properties file.
I am using LOCAL1 as the SYSLOG facility:
log4j.rootLogger=DEBUG, R, stdout ,SYSLOG_LOCAL1
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=${CATALINA_HOME}logs/mylweb.log
log4j.appender.R.MaxFileSize=10MB
log4j.appender.R.MaxBackupIndex=100
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n
log4j.category.org.springframework=INFO
log4j.category.org.directwebremoting=INFO
log4j.category.org.apache.http=INFO
log4j.appender.SYSLOG_LOCAL1=org.apache.log4j.net.SyslogAppender
log4j.appender.SYSLOG_LOCAL1.threshold=DEBUG
log4j.appender.SYSLOG_LOCAL1.syslogHost=localhost
log4j.appender.SYSLOG_LOCAL1.facility=Local1
log4j.appender.SYSLOG_LOCAL1.facilityPrinting=true
log4j.appender.SYSLOG_LOCAL1.layout=org.apache.log4j.PatternLayout
log4j.appender.SYSLOG_LOCAL1.layout.conversionPattern=%d %p [%c] - %m%n
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.
i can't remember how to do this,
i have this log config
# ***** Set root logger level to DEBUG and its only appender to A.
log4j.rootLogger=DEBUG, R
log4j.rootLogger=INFO, A
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.MaxFileSize=100mb
log4j.appender.R.MaxBackupIndex=1000
log4j.appender.R.File=${catalina.base}/logs/server.log
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
# ***** A is set to be a ConsoleAppender.
log4j.appender.A=org.apache.log4j.ConsoleAppender
# ***** A uses PatternLayout.
log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
log4j.logger.org.hibernate.type.BasicTypeRegistry=INFO
log4j.logger.com.opensymphony.xwork2.config.providers.XmlConfigurationProvider=INFO
i want appender A to be info and appender R to be debug. can you remind me how to do that?
log4j.rootLogger=DEBUG, R, A
log4j.appender.A.Threshold=INFO
