I have two appenders, one for file and another for console.
I want Eclipse console to show both file and console logs, but in the same time file to show only its own logs.
How do I do that?
Here is conf.
<appender name="FILE" class="org.apache.log4j.DailyRollingFileAppender">
<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
<param name="Append" value="true"/>
<param name="Threshold" value="INFO"/>
<param name="File" value="${jboss.server.log.dir}/file.log"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p %m%n"/>
</layout>
<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
<param name="Target" value="System.out"/>
<param name="Threshold" value="INFO"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p [%c{1}] %m%n"/>
</layout>
Also, file log is showing only logs from specific package.
<category name="com.project.example" additivity="false">
<appender-ref ref="FILE"/>
<priority value="INFO"/>
</category>
And root:
<root>
<priority value="${jboss.server.log.threshold}"/>
<appender-ref ref="CONSOLE"/>
<appender-ref ref="FILE"/>
</root>
you have to configure your appender in logger tag as below.
<logger name="com.project.example">
<appender-ref ref="FILE" />
<appender-ref ref="CONSOLE" />
</logger>
<root>
<level value="debug" />
<appender-ref ref="CONSOLE" />
</root>

In log4j there are level from trace at the lowest, debug, info, warn, error, and fatal.
I used level info to log my web application with this code
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="abclog" class="org.apache.log4j.DailyRollingFileAppender">
<param name="File" value="/data/abc/abc.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
</appender>
<logger name="com.myapp">
<level value="info" />
<appender-ref ref="abclog"/>
</logger>
<logger name="com.myapp.controller">
<level value="info" />
<appender-ref ref="abclog"/>
</logger>
</log4j:configuration>
It'd produce abc.log contained log from level info to fatal.
Then I tried to move the error log only to another file, error.log.
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="errorlog" class="org.apache.log4j.DailyRollingFileAppender">
<param name="File" value="/data/abc/error.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
</appender>
<appender name="abclog" class="org.apache.log4j.DailyRollingFileAppender">
<param name="File" value="/data/abc/abc.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
</appender>
<logger name="com.myapp">
<level value="error" />
<appender-ref ref="errorlog"/>
</logger>
<logger name="com.myapp.controller">
<level value="error" />
<appender-ref ref="errorlog"/>
</logger>
<logger name="com.myapp">
<level value="info" />
<appender-ref ref="abclog"/>
</logger>
<logger name="com.myapp.controller">
<level value="info" />
<appender-ref ref="abclog"/>
</logger>
</log4j:configuration>
But didn't work, all logger still in abc.log. I found that the logger outputs all those messages equal to that level and also all greater levels than it, that's why the log still in abc.log.
When I deleted abclog and log level info, it worked. It'd show logger from level error (and maybe fatal error if any) on error.log.
But why when I tried to lower the log info to trace / debug without level info or error, it didn't come up with anything, no logger created.
When I put the lowest log4j level, it should show all the log from its level and above like it supposed to do at info level (show log from info to fatal).
Why could it show up with nothing when the level change into trace / debug instead of level info?
Does it really no other way to separate error log to another file from other log?
Try to use the category with additivity set to false. I have not tested, but something like the following should work:
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="errorlog" class="org.apache.log4j.DailyRollingFileAppender">
<param name="Threshold" value="ERROR"/>
<param name="File" value="/data/abc/error.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
</appender>
<appender name="abclog" class="org.apache.log4j.DailyRollingFileAppender">
<param name="File" value="/data/abc/abc.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
</appender>
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<param name="Threshold" value="INFO"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
</appender>
<!-- all error from com.myapp to errorlog only -->
<category name="com.myapp" additivity="false">
<priority value="error" />
<appender-ref ref="errorlog"/>
</category>
<!-- all other log from com.myapp to abclog only -->
<category name="com.myapp" additivity="false">
<priority value="info" />
<appender-ref ref="abclog"/>
</category>
<root>
<!-- all other log to console -->
<appender-ref ref="console"/>
</root>
</log4j:configuration>
If you want to separate com.myapp and com.myapp.controller, you can declare more categories. But you should declare com.myapp.controller before com.myapp.
UPDATE : you can try with filter perhaps is what you need, after that, I have no more idea:
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="errorlog" class="org.apache.log4j.DailyRollingFileAppender">
<param name="Threshold" value="ERROR"/>
<param name="File" value="/data/abc/error.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="levelMin" value="ERROR" />
<param name="levelMax" value="FATAL" />
</filter>
</appender>
<appender name="abclog" class="org.apache.log4j.DailyRollingFileAppender">
<param name="Threshold" value="INFO"/>
<param name="File" value="/data/abc/abc.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="levelMin" value="INFO" />
<param name="levelMax" value="WARN" />
</filter>
</appender>
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<param name="Threshold" value="INFO"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ISO8601}] [%-5p] [%t] {%F:%M:%L} - %m%n"/>
</layout>
</appender>
<!-- all log from com.myapp to special log file -->
<category name="com.myapp" additivity="false">
<appender-ref ref="errorlog"/>
<appender-ref ref="abclog"/>
</category>
<root>

I am new to JasperReport and Log4j, Now I have to Log all log messages related to jasper report to a new log file. As of now it writes to log file and console bit I want it to log only on separate log file. How can achive this.
Here is my log4j.xml file.
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true" xmlns:log4j='http://jakarta.apache.org/log4j/'>

</root> -->
</log4j:configuration>
Please Anyone can help me in this please.
you have to define a new appender:
<appender name="jasper" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="true" />
<param name="maxFileSize" value="10MB" />
<param name="maxBackupIndex" value="10" />
<param name="file" value="${catalina.home}/logs/jasperReports.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{dd-MM-yyyy HH:mm:ss}] [%c{1}] %-5p:%L - %m%n" />
</layout>
</appender>
And a new category with have the apender as reference:
<category additivity="false" name="net.sf.jasperreports">
<priority value="debug" />
<appender-ref ref="jasper"/>
</category>
Looked at quite a few examples on this and have seen some confusing stuff. Here is the log4j.xml file
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %c{1} - %m%n"/>
</layout>
</appender>
<appender name="file" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="false" />
<param name="maxFileSize" value="1000KB" />
<param name="maxBackupIndex" value="5" />
<!-- For Tomcat -->
<param name="file" value="${catalina.home}/logs/demandManage.log" />
<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>
<logger name="com.xxx.demand.domain.data" additivity="true">
<level value="debug" />
<appender-ref ref="file"/>
</logger>
<logger name="com.xxx.rita.serviceserver.controller.AbstractRestController" additivity="true">
<level value="debug" />
<appender-ref ref="file"/>
<appender-ref ref="console" />
</logger>
<logger name="com.xxx.dao.AbstractDAOImpl" additivity="true">
<level value="debug" />
<appender-ref ref="file"/>
<appender-ref ref="console" />
</logger>
<logger name="org.hibernate" >
<level value="warn" />
<appender-ref ref="file"/>
</logger>
<root>
<priority value ="warn" />
<appender-ref ref="console" />
<appender-ref ref="file"/>
</root>
</log4j:configuration>
In my java class:
package com.xxx.dao;
public abstract class AbstractDAOImpl<T, ID extends Serializable> implements AbstractDAO<T,ID>{
private Logger logger = LoggerFactory.getLogger(com.xxx.dao.AbstractDAOImpl.class);
#SuppressWarnings("unchecked")
public T read(ID id){
T response = (T) getCurrentSession().get(clazz, id);
if(response==null){
logger.error(RiskTaker.name.get()+ " tried to load " + clazz + " of " +id);
throw new RuntimeException("hibernate object did not exist");
}
return response;
}
}
So when I am hitting the logger.error message with this configuration, nothing is going to the demandManage.log file or the console. I don't see what's wrong. When I had root set to debug, hibernate of course practically fills up that log file so it does work.
Is there a difference between using level vs priority? Like a slfj4 vs appache logger? The root sets priority but the child loggers are using level.
I am starting tomcat in debug mode and know I am hitting those logger.error statements but the file remains empty. May be I need to flush to it right away?
I previously had the logger in the xml file as fully qualified and in the java class as just class name only but fixing that did nothing. I am wondering what I am missing. Thank you in advance.
I'm using log4j for logs.
I have a class that i want to print to the console only log.info level,
And print to some file log.info + log.debug levels (The same class).
I tried to setup the log4j.xml as follows :
<!--appender to parser file-->
<appender name="parserFile" class="org.apache.log4j.FileAppender">
<param name="File" value="/var/log/java/parser/parser.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{E MMM dd HH:mm:ss} %c : %m%n" />
</layout>
</appender>
<!--appender to the stdout-->
<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{1} - %m%n"/>
</layout>
</appender>
<logger name="parser.ParserMainJava">
<level value="debug" />
<appender-ref ref="parserFile" />
</logger>
<logger name="parser.ParserMainJava">
<level value="info" />
<appender-ref ref="console" />
</logger>
This is my configuration but I can't use 2 loggers with the same package name.
Any suggestions ?
Thanks,
Or.
Just define one logger for "parser.ParserMainJava" with debug level, and add the following parameter to your console appender definition:
<param name="Threshold" value="INFO"/>
In my case I needed to adjust my AppenderRef. Adding the param element to the ConsoleAppender did not work. This element inside Loggers is good.
<Root level="debug">
<AppenderRef ref="FileAppender" />
<AppenderRef ref="ConsoleAppender" level="info"/>
</Root>
I have been on log4j for sometime and read quite a few articles and all look pretty straight forward but when I implement it, it doesnt seem to work.
I have the below requirement :
1-> Need to have 2 files created for 2 different packages :
So I created as per log4j specs and it creates 2 files based on 2 different packages but only the logs logged from our application gets logged into those files.
The logs generated from Spring or Hibernate and Ibatis do not get logged to the file at all, but they get and all other logs do get logged to the console.
I am placing the log4j.xml that I am using, any help would be appreciated :
Also I have tried lots of combinations like from root appender removed the references already mentioned in the logger, adding them back to the root, add addivity to loggers but nothing worked:
<appender name="ConsoleAppender" class="org.apache.log4j.ConsoleAppender">
<param name="Threshold" value="DEBUG"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ISO8601} DSL Service(CONSOLE) %-5p %c [%t]: %m%n%n"/>
</layout>
</appender>
<appender name="FEPOCServiceLog"
class="org.apache.log4j.RollingFileAppender">
<param name="Append" value="true"/>
<param name="maxFileSize" value="100KB" />
<param name="maxBackupIndex" value="5" />
<param name="File" value="C:\\tmp\\DSLService_1.0.log" />
<param name="threshold" value="DEBUG"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{ISO8601} DService(CONSOLE) %-5p %c [%t]: %m%n%n" />
</layout>
</appender>
<appender name="iServiceLog"
class="org.apache.log4j.RollingFileAppender">
<param name="maxFileSize" value="10MB" />
<param name="maxBackupIndex" value="5" />
<param name="File" value="C:\\tmp\\iService_1.0.log" />
<param name="threshold" value="DEBUG"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{ISO8601} iService(CONSOLE) %-5p %c [%t]: %m%n%n" />
</layout>
</appender>

The problem is that Spring and Hibernate don't use log4j.
Hibernate internally uses slf4j, so you need to add slf4j-log4j binding to your classpath in order to redirect its output to log4j, see SLF4J user manual.
Spring uses Commons Logging, you can redirect its output to log4j via slf4j by adding jcl-slf4j bridge and slf4j-log4j binding, see Logging Dependencies in Spring.
