I have this xml config file for log4j2 but the loggers don't work. If I set the referince for root logger as "Errors" of "Info" (my new appenders) when I run the program the logger works and writes the data to logger files but if I set thouse appenders to my new loggers ("Information" and "ErrorLog") the logger doesn't write any data to my log files.
Here is my configuration xml file:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="Console">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
<File name="Info" fileName="logs/info.log">
<PatternLayout>
<Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
</PatternLayout>
</File>
<File name="Errors" fileName="logs/errors.log">
<PatternLayout>
<Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
</PatternLayout>
</File>
</Appenders>
<Loggers>
<Logger name="Information" level="debug">
<AppenderRef ref="Info"/>
</Logger>
<Logger name="ErrorLog" level="error">
<AppenderRef ref="Errors"/>
</Logger>
<Root level="debug">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
Solved!
I modified the Loggers section and I deleted those 2 Loggers.
<Loggers>
<Root level="debug">
<level value="DEBUG" />
<appender-ref ref="Console" />
<appender-ref ref="Info" />
<appender-ref ref="Errors" />
</Root>
</Loggers>

I'm using log4j2 for logging in my app. Basically it's logging uncatched exceptions (Error.log) and logging changes of my data at service layer (journal.log; journalJSON.log).
And here's the thing, when I'm starting service layer tests every log appears in the file and console, but when I'm using application deployed in tomcat they're only in console. What's happening?
<?xml version="1.0" encoding="UTF-8"?>
<configuration status="WARN">
<appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
<File name="Error" fileName="logs/error.log"
immediateFlush="true" append="true">
<PatternLayout pattern=" \n\n %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</File>
<RandomAccessFile name="Journal" fileName="logs/journal.log" immediateFlush="true" append="true">
<PatternLayout pattern="[%d{yyyy-MM-dd HH:mm:ss.SSS}] %msg%n"/>
</RandomAccessFile>
<File name="JournalJSON" fileName="logs/journalJSON.log" immediateFlush="true" append="false">
<JSONLayout complete="true" charset="UTF-8" compact="false" eventEol="false"/>
</File>
</appenders>
<Loggers>
<Logger name="com.user.controller" level="error" additivity="false">
<AppenderRef ref="Error" level="error"/>
<AppenderRef ref="Console" level="error"/>
</Logger>
<Logger name="com.user.service" level="info" additivity="false">
<appender-ref ref="JournalJSON" level="info"/>
<appender-ref ref="Journal" level="info"/>
<appender-ref ref="Console" level="info"/>
</Logger>
<Root level="warn">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
Well, there are a couple of possibilities I can think of:
Your configuration file isn't being found and it is using the default configuration.
The logger for your application isn't com.user.controller or com.user.service and the root logger is being used.
get a logger instance named "com.foo"
Logger logger = Logger.getLogger("com.foo");
Now set its level. Normally you do not need to set the level of a logger programmatically. This is usually done in configuration files.
logger.setLevel(Level.INFO);
this is an example of log4j2 configuration
<Configuration status="WARN">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
<Appender type="File" name="File" path="location/to/logging/space/file.txt">
<Layout type="PatternLayout" pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Appender>
</Appenders>
<Loggers>
<Logger name="com.foo" level="trace" additivity="false">
<AppenderRef ref="File"/>
</Logger>
<Root level="error">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
I am getting a lot of DEBUG messages in my logs. I want to suppress these, while preserving the INFO and ERROR messages. Here is my log4j2.xml:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<!-- Author: Crunchify.com -->
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d [%t] %5p %c - %m%n" />
</Console>
<RollingFile name="RollingFile" filename="test.log"
filepattern="${LOG_PATH}${LOG_NAME}Log.%d{yyyyMMdd}.log.gz">
<PatternLayout pattern="%d [%t] %5p %c - %m%n" />
<Policies>
<SizeBasedTriggeringPolicy size="100 MB" />
</Policies>
<DefaultRolloverStrategy max="20" />
</RollingFile>
<NoSql name="elasticAppender">
<Elasticsearch cluster="test" host="test" port="test" index="test" type="log4j2"/>
</NoSql>
</Appenders>
<Loggers>
<Root level="debug">
<AppenderRef ref="NoSql" />
<AppenderRef ref="RollingFile" />
</Root>
<Logger name="test" level="info" additivity="false">
<AppenderRef ref="RollingFile" />
</Logger>
<Logger name="test" level="info">
</Logger>
<Logger name="test" level="INFO">
</Logger>
<Logger name="com.datastax.driver.core" level="INFO">
</Logger>
</Loggers>
</Configuration>
Does anyone know what change needs to be made here?
According to the Log4j manual, you might want to change <Root level="debug"> to <Root level="info">.
I am new to unix. I have below log4j2 config file. When I use this file in unix environment, the file app.log is not created. Could any one tell me how to redirect the logs to file in unix environment

You have to change the filename :
<File name="file" fileName="/tmp/app.log">

I think your real problem is that you have two root loggers. Try the following instead:
<Loggers>
<Root level="trace">
<AppenderRef ref="CONSOLE" />
<AppenderRef ref="file" />
</Root>
</Loggers>
You also need to fix the filename as mentioned by #ToYonos.
Can we dsable log print for some customm creating Logger?
I have two loggers:
Root logger
Metrics Logger (which prints into file)
<Configuration status="WARN">
<Appenders>
<File name="file" fileName="app.log">
<PatternLayout>
<Pattern>%d %p %c{1.} [%t] %m %ex%n</Pattern>
</PatternLayout>
</File>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d{yyyy-mm-dd HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<logger name="metrics" level="info" additivity="true">
<AppenderRef ref="file"/>
</logger>
<root level="info">
<AppenderRef ref="STDOUT"/>
</root>
</Loggers>
</Configuration>
I want to disable print messages in console for File logger
The key to understanding is here
http://logging.apache.org/log4j/2.x/manual/configuration.html#Additivity
The root logger is a parent of the logger "metrics". The log event of "metrics" is then passed to root logger's appender ("STDOUT"). This is known as additivity. It is possible to disable it by setting the additivity attribute on the logger "metrics" to false.
<logger name="metrics" level="info" additivity="false">
<AppenderRef ref="file"/>
</logger>
