I want to create two log file.
Because my project has two modules and log each module in separate log files.
After that ,I have to log each module logging data independently .i have Single Log4j file.when i use appender -ref inside the root then i can achive but at that time aop or java logging cant appear in that file only manualy logger msg shown there
Try Something like :
<log4j:configuration>
<appender name="fileAppender1" class="org.apache.log4j.RollingFileAppender">
<param name="Threshold" value="ALL" />
<param name="MaxFileSize" value="3KB" />
<param name="MaxBackupIndex" value="10" />
<param name="File" value="F:/logs/Testing/Project_moduleOne.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{MMM-dd-yyyy HH:mm:ss:SSS} %-5p %m%n" />
</layout>
</appender>
<appender name="fileAppender2" class="org.apache.log4j.RollingFileAppender">
<param name="Threshold" value="ALL" />
<param name="MaxFileSize" value="3KB" />
<param name="MaxBackupIndex" value="10" />
<param name="File" value="F:/logs/PAD_Testing/Project_moduleTwo.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{MMM-dd-yyyy HH:mm:ss:SSS} %-5p %m%n" />
</layout>
</appender>
<!--sets the priority log level for org.springframework -->
<logger name="com.sp.logger1" additivity="false">
<appender ref="fileAppender1"/>
</logger>
<logger name="com.sp.logger2" additivity="false">
<appender ref="fileAppender2" />
</logger>
<!--sets the default priority log level -->
<root>
<priority value="all"></priority>
<appender-ref ref="fileAppender1" />
<appender-ref ref="fileAppender2" />
</root>
</log4j:configuration>

Okay, this is driving me nuts. I have an app that uses log4j 1.2.16, my configuration file is properly picked up and log4j writes to the file that I want, BUT it only logs error level.
Code:
import org.apache.log4j.Logger;
- (... code omitted)
private static final Logger LOGGER = Logger.getLogger(PostLoginController.class);
LOGGER.debug("TOTO debug");
LOGGER.info("TOTO Info");
LOGGER.warn("TOTO warn");
LOGGER.error("TOTO error");
XML:
<appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
<param name="File" value="/jboss/jboss-eap-6.4/standalone/log/myLogFile.log"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} %-5p [%t:%c] : %m%n"/>
</layout>
</appender>
<!-- Root Logger -->
<root>
<priority value ="debug" />
<appender-ref ref="fileAppender"/>
</root>
When my app runs myLogFile is created and I can see the error log in it, but not the other ones:
2019-06-06 19:37:31 ERROR [http-/0.0.0.0:8080-2:my.classpath.PostLoginController] : TOTO error
Any idea what's wrong here?
You have to use like this for logging debug to error.
<log4j:configuration debug="false">
<appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">
<param name="target" value="System.out" />
<param name="threshold" value="debug" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601} %-5p [%c{1}] - %m%n" />
</layout>
</appender>
<appender name="fileAppender" class="org.apache.log4j.FileAppender">
<param name="file" value="/jboss/jboss-eap-6.4/standalone/log/myLogFile.log"/>
<param name="append" value="false" />
<param name="threshold" value="debug" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601} %-5p [%c{1}] - %m%n" />
</layout>
</appender>
<root>
<priority value="info" />
<appender-ref ref="default.console" />
<appender-ref ref="default.file" />
</root>
</log4j:configuration>
Okay, figured it out. I had to add
<category name="my.classpath">
<priority value="all" />
<appender-ref ref="fileAppender" />
</category>
because somehow the rootLogger level can't be altered.
I have below log4j configuration. when file reaches its max size , it is not rolling but when I restart server then rolling is working.
Please let me know what I am wrong in my configuration.
<appender name="ALog" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="true" />
<param name="maxFileSize" value="10KB" />
<param name="maxBackupIndex" value="10" />
<param name="file" value="logs/Log.txt" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
</layout>
</appender>
<root>
<priority value ="debug"/>
<appender-ref ref="ALog"/>
</root>
Thanks.
You have to do :
<appender name="file" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="false" />
<appender-ref ref="file"/>
I was making a log4j.xml for one of my projects in netbeans .
Here is its contents :
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="FILE" class="org.apache.log4j.DailyRollingFileAppender">
<param name="file" value="${catalina.home}/logs/MyLogs.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd" />
<param name="Threshold" value="INFO" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m #]%n" />
</layout>
</appender>
<appender name="sqlLogs" class="org.apache.log4j.DailyRollingFileAppender">
<param name="file" value="${catalina.home}/logs/MySqlLogs.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd" />
<param name="Threshold" value="TRACE" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
</layout>
</appender>
<root>
<level value ="INFO" />
<appender-ref ref="FILE" />
</root>
<logger name="org.hibernate.SQL" additivity="false" >
<level value="DEBUG" />
<appender-ref ref="sqlLogs" />
</logger>
</log4j:configuration>
Now i want sql logs to go only to MySqlLogs.log but they are appearing on both MySqlLogs.log and catalina.out .
The format of logs in catalina.out is
Hibernate : select ....
Hibernate : insert into ....
Can anyone help me out on this please .
You can stop it, on your env shared properties.
hibernate.show_sql=true
you have to add the following line in your hibernate_cfg.xml file
show_sql to false
and in your file loging.properties :
log4j.logger.org.hibernate=debug
log4j.logger.org.hibernate.type=trace
log4j.logger.org.apache=debug
I have a huge code base which serves info requests about colleges. There is a base framework code, and we have some separate packages for college1, college2, etc.,
Whenever there is a request for some info about college X, both framework code and college specific code both are triggered. I want to see logs generated for all requests for Company X to go to one location, and company Y to go to one location.
How do I use JUL or apache's logging.properties file to achieve this ? How do I ensure logs written by common framework libraries for company X go to one location, and logs written by common framework libraries for company Y go to some other location ?
I would have an xml file that contain the appenders to specify what packages go into what log file.
You can then load the xml file in your application entry point. Below is an example I have used in my current project
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<!-- appenders -->
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out" />
<param name="threshold" value="error" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%t] %p %c - %m%n" />
</layout>
</appender>
<appender name="codebaseXAppender" class="org.apache.log4j.RollingFileAppender">
<param name="File" value="codebaseX.log" />
<param name="MaxFileSize" value="10MB" />
<param name="MaxBackupIndex" value="10"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%t] %d %p %c - %m%n"/>
</layout>
</appender>
<appender name="codebaseYAppender" class="org.apache.log4j.RollingFileAppender">
<param name="File" value="codebaseY.log" />
<param name="MaxFileSize" value="10MB" />
<param name="MaxBackupIndex" value="10"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%t] %d %p %c - %m%n"/>
</layout>
</appender>
<!-- Root Logger -->
<root>
<priority value="error" />
<appender-ref ref="console" />
</root>
<!-- Application logger -->
<logger name="com.codebasePackageX" additivity="true">
<level value="info" />
<appender-ref ref="codebaseXAppender" />
</logger>
<!-- Application logger -->
<logger name="com.codebasePackageY" additivity="true">
<level value="info" />
<appender-ref ref="codebaseYAppender" />
</logger>
</log4j:configuration>
Is there a way to specify a pattern for an original filename?
I essentially want to do the following:
<param name="file" value="%d{yyyy/MM/dd HH:mm:ss}: %m%n_testlog.log"/>
How would I go about doing this?
I have a daily rolling log but I do it a little differently, using TimeBasedRollingPolicy from log4j extras:
<log4j:configuration debug="true">
<appender name="roll" class="org.apache.log4j.rolling.RollingFileAppender">
<param name="append" value="true" />
<param name="encoding" value="UTF-8" />
<!-- The active file to log to -->
<param name="file" value="/location/to/log/current.log />
<rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
<param name="FileNamePattern"
value="/location/to/log/archive/oldLog-%d{yyyy-MM-dd}.log" />
</rollingPolicy>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{DATE} %5p %c{2} - %m%n" />
</layout>
</appender>
<logger name="mypackage">
<level value="debug" />
<appender-ref ref="roll" />
</logger>
</log4j:configuration>
The above is in my code, which I based on this entry at the log4j Wiki.

I'm not sure this would help you:
<param name="File" value="Info"/>
<param name="DatePattern" value="yyyy-MM-dd-HH-mm-ss'_testlog.log'"/>
