How do I print just the INFO levels?
My current log is printing all INFO, WARN, ERROR and FATAL levels to console - I understand why this is happening. (because they are all above INFO)
Is there a way to just specify that just and only just, INFO levels get sent to the console appender and not everything above it?
Currently have the following log4j2 xml:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" name="App" packages="">
<Appenders>
<File name="logFile" fileName="C:\Users\user\workspace\logs\log.out">
<PatternLayout>
<Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
</PatternLayout>
</File>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<Logger name="com.App" level="info" additivity="false">
<AppenderRef ref="logFile" level="error"/>
<AppenderRef ref="Console" level="info"/>
</Logger>
<Root level="error">
<AppenderRef ref="logFile" />
</Root>
</Loggers>
Need to use a ThresholdFilter;
<ThresholdFilter level="WARN" onMatch="DENY" onMismatch="ACCEPT" />
This blocks the WARN level and everything above it. So now it only accepts info.

I try to config log4j to appends loggs in diffrent color per log type (INFO, ERROR, DEBUG etc.)
Here is my log4j2.xml:
<Configuration monitorInterval="60">
<Properties>
<Property name="log-path">applogs</Property>
</Properties>
<Appenders>
<Console name="Console-Appender" target="SYSTEM_OUT">
<PatternLayout>
<pattern>
%highlight{%d{HH:mm:ss.SSS} %-5level %logger{36}.%M() [%L] - %msg%n}{FATAL=red, ERROR=red, WARN=yellow, INFO=green}
</pattern>
</PatternLayout>
</Console>
<someMoreAppenders>
</Appenders>
<Loggers>
<Logger name="RepositoriesController" level="info" additivity="false">
<AppenderRef ref="Console-Appender"/>
</Logger>
<Root level="error" additivity="false">
<AppenderRef ref="Console-Appender"/>
</Root>
</Loggers>
</Configuration>
And in class RepositoriesController, i create logger in this way:
private static final Logger logger = LogManager.getLogger("RepositoriesController");
logger.info("Hello, World!");
My log4j.properties are empty. Output seems to be formatted used by my pattern but font color is still white:
Intelij console
i tried to add this properties:
spring.main.banner-mode=off
spring.output.ansi.enabled=ALWAYS
and modify pattern but without succesed, any advices?
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t]
%highlight{%level}{FATAL=bg_red, ERROR=red, WARN=yellow, INFO=green, DEBUG=blue} - %msg%n" />
</Console>
%highlight{%level} - using this you can highlight colors for different levels of logs.
This will generate output as:
I am specifying the filename to log4j2 logger in the XML as below. All works fine but i get the error
2017-09-06 16:54:33,496 main ERROR Unknown object "RandomAccessFile" of type org.apache.logging.log4j.core.appender.RandomAccessFileAppender is ignored: try nesting it inside one of: ["Appenders", "Loggers", "Properties", "Scripts", "CustomLevels"].

This error is coming because RandomAccessFile appender is not defined within <Appenders> XML element.
Below is the correct way of defining any appender including RandomAccessFile appender -
<?xml version="1.0" encoding="UTF-8"?>
<Configuration package="log4j.test"
status="WARN">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{dd/MM/yyyy HH:mm:ss} %c %m%n"/>
</Console>
<RandomAccessFile name="FILE" fileName="${sys:log4j.saveDirectory}/CMSAutomation.${date:yyyy-MM-dd_hh-mm-ss}.log" append="true" immediateFlush="false">
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-6p %C{1}.%t:%L >>> %m%n"/>
</RandomAccessFile>
</Appenders>
<Loggers>
<Logger name="log4j.test.Log4jTest" level="debug">
<AppenderRef ref="Console"/>
</Logger>
<Root level="trace">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
You can check the same in log4j2 documentation here.
Additional one point, you are not using RandomAccessFile appender in any logger. If you will not define it in any logger, it wouldn't work.
the following log4j2 configuration always results in empty log files and everything getting written to console. I don't want anything on the console except for the errors. Could you please help me give a hint on where I am going wrong?

Your configuration has the Console appender commented out so it shouldn't be possible to have any logs directed to it. Are you sure your configuration is being read? Since you have trace enabled you should see logs generated when it is processed.
I'd like to configure log4j 2 with two different patterns in same appender. i.e., Whenever there is an error, a specific pattern should be present in the log file. I am not trying two different log files, but two different pattern in same log file. Whenever there is an error, I would see "MYDOMAINDOTCOM_SUPPORT_NEEDED" and this string will trigger an automatic email to support team.
I have the below configuration which prints error message in "RollingFile" appender only and "RollingFileError" appender is ignored. What am I missing ?
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG">
<Properties>
<Property name="log-path">/documents/log</Property>
</Properties>

<RollingFile name="RollingFile" fileName="${log-path}/myexample.log"

immediateFlush="true">
<PatternLayout>
<pattern>%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %X{packetRefId} - %msg%n</pattern>
<!-- %d{dd/MMM/yyyy HH:mm:ss,SSS}- %c{1}: %m%n -->

You should never configure two appenders to write to the same file. Having two rolling file appenders that both use the same file and roll over to the same file pattern is never going to work correctly.
Also, your configuration would end up with all error messages being logged twice; once with the RollingFile appender due to its debug level, and once on the RollingFileError appender due to its error level.
Instead, you should have a single rolling file appender and use a PatternSelector to decide which pattern to use. See http://logging.apache.org/log4j/2.x/manual/layouts.html#Pattern_Selectors for documentation on pattern selectors.
in the config file how to separate the package in different appaender using asynch
i have two different package and using different appender i want separate log output
first two appender is different package and third appender is different one
and i need all appender connect to asynch...
pls help me to solve this
here my config file..
<?xml version="1.0" encoding="UTF-8"?>
<configuration strict="true" status="WARN">
<appenders>
<Console name="CONSOLE" target="SYSTEM_OUT">
<PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n" />
</Console>
<File name="MyFile" fileName="Logger/knight.log">
<PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n" />
</File>
<File name="Except" fileName="log1/Execption9.log">
<PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n" />
</File>
<Async name="Async">
<appender-ref ref="CONSOLE" />
<appender-ref ref="MyFile" />
<appender-ref ref="Except" />
</Async>
</appenders>
<loggers>
<root level="all">
<appender-ref ref="Async" />
</root>
</loggers>
</configuration>
You could configure three separate AsyncAppenders, one for each of the File appenders, and one for console, then configure root as:
<root>
<appender-ref ref="async-console" level="info" />
<appender-ref ref="async-file1" level="trace" />
<appender-ref ref="async-file2" level="error" />
</root>
But this solution gives you three threads. Why not use AsyncLoggers (using the selector command line option, see the docs for AsyncLoggers)?
That way you only have one logging thread, and it is probably a lot faster too...
