I am using org.apache.log4j.rolling.RollingFileAppender to generate daily logs.
It generates daily logs in windows, but it is not generating logs in linux.
Help is greatly appreciated!
Below is the log4j.xml file:
<param name="append" value="true" />
<param name="encoding" value="UTF-8" />
<rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
<param name="FileNamePattern" value="D:/source/logs/passports.log.%d{yyyy-MM-dd}.log"/>
</rollingPolicy>
<layout class="org.apache.log4j.PatternLayout">
<!-- The log message pattern -->
<param name="ConversionPattern" value="%d [%t] %-5p {%c} %m%n" />
</layout>
<root>
<priority value="info,debug,error" />
<appender-ref ref="ROLL" />
</root>
Your FileNamePattern needs to reflect the location of the file, specific to the server/workstation the application is running in.
In the snippet you gave, I see that the value for FileNamePattern is D:/source/logs/passports.log.%d{yyyy-MM-dd}.log.
The "D:" suggests to me that this is for your windows box.
Replace this value with the location that your linux box would hold the log file, for example: /var/source/logs/passports.log.%d{yyyy-MM-dd}.log

We're experiencing some stoppages on our log4j(v1.2.8) INFO logs. We're using a WebSphere(8.5.5) clustered server(vertical) with 3 members that runs on a single machine(UNIX). Stoppage is random; no specific file size, time or when about to rollover
We've first suspected that is a volume related problem as we've tested before on a lower volumed server the problem doesn't occur. I've later tested overloading this server but I could not replicate the problem.
Average daily production is 175,000 INFO lines. A workaround is available by just changing the timestamp of the log files to resume logging.
Already looked into the suggested fix on Log4j suddenly stops logging but nothing seemed to work. I'm hoping I could get some advise on were to look. Thank you.
log4j.xml:

The value of ${com.test.log.server.name} is declared in WebSphere JVM custom properties on each application server.
Any help would be greatly appreciated.
I have a problem.
Log4j dont want write to console and to file with system variable in path. Only write to file with simple path.
Configuration of my log4j.
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p: %c - %m%n" />
</layout>

<!-- Root Logger -->
<root>
<priority value="info" />
<appender-ref ref="file1" />
<appender-ref ref="console" />
</root>
</log4j:configuration>
You are declaring
appender name="file" class="org.apache.log4j.DailyRollingFileAppender"
and in root tag you write
appender-ref ref="file1"
As there is no such file1. Due to this log4j is not working for you.
I found where problem is. It is in Jboss, because jboss have his own logger and it doesn't allow to write to console. You must change configuration of Jboss logger. But I don't know why it does not allow to use system variable.
In my case,
I have configured my log4j.xml like this.
<appender name="FILE" class="org.apache.log4j.RollingFileAppender">
<errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler" />
<param name="File" value="F:/myLogger.log" />
<param name="Append" value="true" />
<param name="MaxFileSize" value="20000KB" />
<param name="MaxBackupIndex" value="400" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p: %d{dd MMM yyyy HH:mm:ss.SSS} %-5l - %m%n%n" />
</layout>
</appender>
<!-- Root Logger -->
<root>
<priority value="error" />
<appender-ref ref="FILE" />
</root>
and put log4.xml file in source package.
but logger file is not created at specified folder.Let me know the exact path.
(it may be tha t i am using some external JAR which may have log4j.xml) so how to give priority to root application log4j.xml file.
I am trying to use a common log4j xml for subprojects in tomcat. There is a Parent project deployed already and part of the parent project are three other projects. Two projects A and B already exist and the logging works fine. I am adding a new project C and updated the log4j like below. I do see the ProjectC.log file being created (which is happening when tomcat starts up), but there are no Project C related log statements in this file (or any other file). This is my current log4j xml :
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"
debug="true">
<appender name="rootAppender" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n"/>
</layout>
</appender>
<appender name="ProjectAAppender" class="org.apache.log4j.RollingFileAppender">
<param name="file" value="${catalina.base}/logs/projectA.log"/>
<param name="Append" value="true"/>
<param name="MaxFileSize" value="100000KB"/>
<param name="MaxBackupIndex" value="3"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %c %x - %m%n"/>
</layout>
</appender>
<appender name="ProjectBAppender" class="org.apache.log4j.RollingFileAppender">

The way I get my log4j instance is using the slf4j LoggerFactory :
LoggerFactory.getLogger(clazz)
I have declared dependencies for log4j(1.2.14), slf4j-log4j12(1.4.1) jar files in my pom.
This setup works fine when I execute Project C independently (when running junit test cases).
How can I make logging work for project C ? Any changes that I should be making to my log4j xml ? Thank you.
Turns out I was using the wrong properties file. In the actual log4j.properties file all I had to do was to create a new appender named Project C and added this line instead of registering with the rootCategory :
log4j.logger.com.projectC.related.package=DEBUG, ProjectCAppender
I'm using log4net v1.2 with a Windows Service App. My RollingFileAppender seems not to work. I'm pasting the logging sections of my service.exe.config below. Can anyone advise where I'm going wrong?
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
.....(lots of other config stuff)
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender,log4net" >

<param name="MaximumFileSize" value="20MB" />
<param name="MaxSizeRollBackups" value="10" />
<param name="StaticLogFileName" value="true" />
<param name="Threshold" value="ALL" />
<param name="RollingStyle" value="Composite" />
<param name="appendToFile" value="true" />
<layout type="log4net.Layout.PatternLayout,log4net">

</appender>
...(stuff in between)

</logger>
The user your windows service is running as might not have write permission for the log file.
Another possibility is that you forgot to execute XmlConfigurator.Configure();
try writing:
<log4net debug="true">
it will post all errors to console.
thanks to everyone who responded. I dont know what i changed but my logging has started working fine.
Posting my logging sections. I didnt change anything in the code, except a line in the AssemblyInfo.cs:
[assembly: log4net.Config.Domain(UseDefaultDomain=true)]
Thanks again.:)
