I'm trying to print my log messages to a file. At this point, it only logs to the console which is not ideal for future support.
My log4j.properties file looks like this:
log4j.rootCategory=DEBUG, stdout, logfile
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.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File:/apps/wlserver10/bpdomain/servers/HRServer/logs/HRServer.log
log4j.appender.logfile.MaxFileSize=4MB
log4j.appender.logfile.MaxBackupIndex=10
log4j.appender.logfile.Append=true
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n
This works fine on my local weblogic instance, but when I try to deploy it to the server it doesn't write the log file.
Can anyone please help me find why?
Thanks in advance

Is it the missing = after File instead of : ?
log4j.appender.logfile.File:/apps/wlserver10/bpdomain/servers/HRServer/logs/HRServer.log
Did you miss '=' in this part of your configuration:
log4j.appender.logfile.File**:/**apps/wlserver10/bpdomain/servers/HRServer/logs/HRServer.log

I want to see the INFO level logs that Ignite prints during its running(so that it will help me on what Ignite is doing). I am using the following log4j.properties to make Ignite print INFO level logs,but the logs are not printed out.
Are there special configuration to make Ignite logs printed out?
Thanks.
log4j.rootCategory=INFO, stdout , R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%p %d - [TS] %c %M(%L) - %m%n
log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.File=c:/ioc.ignite.log
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %d - [TS] %c %M(%L) - %m%n
log4j.logger.org.apache.ignite=INFO
log4j.logger.org.springframework=WARN
Please follow below steps:
e.g. if you are using log4j for logging
configure ignite/config/ignite-log4j.xml in gridLogger of IgniteConfiguration
e.g.
.........
uncomment "CONSOLE" appender in ignite/config/ignite-log4j.xml
copy ignite/libs/optional/ignite-log4j/log4j.jar and ignite/libs/optional/ignite-log4j/ignite-log4j.jar in ignite/libs/ folder
you can also set IGNITE_LOG_HOME environment variable to redirect the logs to any file
You should use <CLASSPATH>/config/ignite-log4j.xml file instead of log4j.properties.
below is Log4J.properties configuration ( Using jar "log4j-1.2.17.jar")
log4j.logger.devpinoyLogger=DEBUG, dest1
log4j.appender.dest1=org.apache.log4j.RollingFileAppender
log4j.appender.dest1.maxFileSize=1KB
log4j.appender.dest1.maxBackupIndex=3
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%d{dd/MM/yyyy HH:mm:ss} %c%m%n
log4j.appender.dest1.File=log\\Application.log
log4j.appender.dest1.Append=false
but once maxFileSize is reached backup log file is generated as Application.log.1
I want file to be generated as Application1.log
I got the solution using RollingFileAppender.
log4j.logger.devpinoyLogger=DEBUG, dest1
log4j.appender.dest1=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.dest1.rollingPolicy=org.apache.log4j.rolling.FixedWindowRollingPolicy
log4j.appender.dest1.triggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy
log4j.appender.dest1.triggeringPolicy.MaxFileSize=100
log4j.appender.dest1.rollingPolicy.FileNamePattern=C:\\TRB Workspace\\TRBAutomationFramework\\log\\Application-%i.log
log4j.appender.dest1.rollingPolicy.ActiveFileName=C:\\TRB Workspace\\TRBAutomationFramework\\log\\Application.log
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%d{dd/MM/yyyy HH:mm:ss} %c %m%n
log4j.appender.dest1.Append=false
Also required "apache-log4j-extras-1.2.17.jar"
I did not test, but as explained by Koning, you may try to add this to your properties:
log4j.appender.dest1.rollingPolicy=org.apache.log4j.rolling.FixedWindowRollingPolicy
log4j.appender.dest1.triggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy
log4j.appender.dest1.rollingPolicy.FileNamePattern=log\\Application-%i.log
log4j.appender.dest1.rollingPolicy.ActiveFileName=log\\Application.log
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 the following log4j.properties file. what i want to do is log everything at the level INFO or above to the console. however, for anything that falls in the demo.* package, i want to log everything at the DEBUG level to a file. my log4j.properties below does not seem to work. what happens is that any DEBUG message from demo.* still gets output to the console. any idea what i am doing wrong?
how can i exclude demo.* from logging to the console?
log4j.rootLogger=INFO, C
log4j.logger.demo=DEBUG, R1
log4j.appender.C=org.apache.log4j.ConsoleAppender
log4j.appender.C.target=System.err
log4j.appender.C.layout=org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{2}: %m%n
log4j.appender.R1=org.apache.log4j.RollingFileAppender
log4j.appender.R1.File=output.log
log4j.appender.R1.MaxFileSize=5MB
log4j.appender.R1.MaxBackupIndex=5
log4j.appender.R1.layout=org.apache.log4j.PatternLayout
log4j.appender.R1.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{2}: %m%n
sorry, never mind. i solved it by setting the threshold of the console appender.
log4j.appender.C.threshold=INFO
I have a small problem using log4j and FileAppender. When I am using ConsoleAppender, everything is working well but FileAppender won't ever produce a file (or write into a file). Moreover, I have no errors concerning log4j in the osgi console.
Here's my configuration :
# main link (console or file, depending on what we want)
# log4j.category.com.foo=DEBUG, console
log4j.category.com.foo=DEBUG, file
# log4j.category.com.foo=DEBUG, console, file
# console logging
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-4r %-5p %c %x - %m%n
# file logging
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=C:\\Users\\foo\\some_file.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%-4r %-5p %c %x - %m%n
Note that the ConversionPattern attributes are exactly the same in the two appenders.
I have tried to change the File argument to write the log in the "run" directory but it didn't do anything.
I also tried to add log4j.appender.file.ImmediateFlush=true without success.
Have I missed something (obvious ?) somewhere ? It sound strange that log4j isn't even able to write a simple log in a file....
Thanks a lot in advance for your help.
Replace :
log4j.category.com.foo=DEBUG, console
By :
log4j.category.com.foo=DEBUG, console, file
I know this is old but for other Googlers...
For me it was simply using wrong package.
I used org.apache.logging.log4j instead org.apache.log4j
If you are using Maven use this:
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
