My Google foo is letting me down today! I am trying to configure log4j2 so that I can access the loggers via JMX and change their log levels.
However, when I hook everything up, none of the loggers show up in the JMX tree (or log4j-jmx-gui) as shown in the log4j2 JMX docs. Only the log4j2 ContextSelector and StatusLogger in the JConsole attribute tree and the StatusLogger tab in the log4j-jmx-gui (stand-alone or as a plugin) show up. No LoggerContext elements.
I've googled and not come up with anything! That probably means I'm missing something somewhere. Any help would be greatly appreciated by me and wall which I'm banging my head against :)
I'm using Log4j2 beta9 with Java 1.6.0_45-b06 on win7. I have tried it on Java 7 and it results in the same behaviour.
The log4j2 dependencies being used:
log4j-api-2.0-beta9.jar
log4j-core-2.0-beta9.jar
My log4j2.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<Configuration status="debug">
<Appenders>
<Console name="log-test" target="SYSTEM_OUT">
<PatternLayout pattern="%d{DATE} %-5p LJX2 %c{1}: %m%n" />
</Console>
</Appenders>
<Loggers>
<Logger name="top.Log4J2TestApp" level="debug" additivity="false">
<AppenderRef ref="log-test" />
</Logger>
<Root level="trace">
<AppenderRef ref="log-test" />
</Root>
</Loggers>
</Configuration>
My test program:
package top;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
public class Log4J2TestApp {
public static void main(String[] args) {
System.out.println("******** Started ZZZ ****************");
Logger log = LogManager.getLogger(Log4J2TestApp.class);
int cnt = 0;
while (true) {
log.warn("=========== Test message: {} ================", cnt++);
Thread.sleep(1000);
}
}
}
The output of the test program looks like this:

Your config looks good, the only thing a bit suspicious is the error. The error does seem to occur in the LoggerContext constructor, so it may be related after all.
You may have found a bug. Would you mind reporting this issue in the log4j2 issue tracker so the log4j team can look at it?
Log4j2 uses ClassLoaderContextSelector as ContextSelector by default. In some cases (it is not clear for me, may be for simple applications like yours) it returns nothing as getLoggerContexts() method call result. No logger contexts - nothing no show, so LoggerContext category doesn't present in the tree. It can be fixed by selecting another ContextSelector implementation. I used org.apache.logging.log4j.core.selector.BasicContextSelector for this purpose. It can be set using system property named "Log4jContextSelector". See docs for more info.
It solves my problem, I hope it helps to solve yours too.

I'm running JUnit testcases with WireMock. Embedded Jetty Server is configured as follows.
#Before
public void setup() {
final ResponseTemplateTransformer theTemplateTransformer =
new ResponseTemplateTransformer(false);
templateTransformerName = theTemplateTransformer.getName();
mWireMockServer = new WireMockServer(
WireMockConfiguration
.options()
.notifier(new ConsoleNotifier(false))
.extensions(theTemplateTransformer));
mWireMockServer.start();
}
The output of the setup() method alone is very verbose, about 200 lines long. It starts like this:
> Task :processResources
> Task :classes
> Task :compileTestJava
> Task :processTestResources
> Task :testClasses
> Task :test

I do not want to print out DEBUG logs, just INFO level stuff. I tried to do this by changing the WireMock Configuration as follows. What I'm doing is described in the official documentation, section Notification (logging), so feel free to have a look.
.notifier(new ConsoleNotifier(false)) //attribute verbose is set to false
Also tried to solve this by adding a log4j.properties file under src/test/resources/
log4j.rootLogger=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.logger.org.apache.http.wire=INFO
Can someone help me please?
This worked in my case (Spring, Logback) - src/test/resources/logback-test.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<include resource="org/springframework/boot/logging/logback/base.xml" />
<!-- Decrease amount of logs from Jetty started by WireMock -->
<logger name="org.eclipse.jetty" level="info"/>
<logger name="org.eclipse.jetty.server.handler.ContextHandler" level="warn"/>
</configuration>
In my project I use Log4j to process all logging. The config I use:
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d - %-5p %-10c - %m%n"/>
</Console>
<File name="file" fileName="logs/TAF_${sys:current_date}.log">

</PatternLayout>
</File>
</Appenders>
<Loggers>
<Root level="trace">
<AppenderRef ref="file" level="DEBUG"/>
<AppenderRef ref="STDOUT" level="DEBUG"/>

2018-11-19 16:12:59,550 main ERROR Unable to locate appender "file" for logger config "root"
The first error is in dutch, which translates to: "The filename, directory name, or volume label syntax is incorrect".
This Log4J config file is used under an Ubuntu environment and works perfectly. Now I have added a Win10 machine to the pool, but I receive this error.
What am I doing wrong?
I tried to make the path absolute, "c:/Project/logs/TAF_${sys:current_date}.log", but it did not solve the problem. Every user has read/write access to the logs directory.
Other stuff I tried:
Log4j logfile error FileNotFoundException
#edit:
For what I can see, it looks like log4j is trying to create a file named "TAF_${sys:current_date}.log". That ofcourse doesn't work, because { and } are not valid for filenames. When the "_${sys:current_date}" is removed, I am able to create the log file. How am I able to use the expression again, to add the current date/time?
#edit2:Found the answer here. I needed to set the system property "current_date" in the code.
I could use some help with my log4j2 configuration. When I debug the logger, it looks like it shuts down all of the appenders, and then I never receive any application logs. Luckily I know that log4j is at least finding the properties file and giving logger initialization debug output.
Here is my log4j2.properties file:
status = debug
name = PropertiesConfig
filters = threshold
filter.threshold.type = ThresholdFilter
filter.threshold.level = info
appenders = console
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{yy-MM-dd HH:mm:ss:SSS} %-5p %c{1}:%L - %m%n
rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT
appender.file.type = File
appender.file.name = application
appender.file.fileName=${filename}/propertieslogs.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
Here is the logger debug init output:

Thanks for any help! I need it.
I'd really like to get the async appenders working at some point, but its hard to find examples via the log4j2.properties syntax for log4j2

I just experienced what seems to be a similar problem. In my case, I was able to receive application logs, but with what appeared to be a default log4j2 config. The logs were INFO level. None of the levels set for loggers in the log4j2 config (XML) were being applied. I saw a very similar output in the startup logs as posted by the OP, including the message about "shutting down OutputStreamManager".
Mine is a spring-boot application and I was able to resolve the problem by disabling the spring-boot LoggingSystem. I added this system variable to my startup command:
-Dorg.springframework.boot.logging.LoggingSystem=none
Once I did that, the logging worked as expected, according to the levels set in my log4j2 XML config. It appears to be spring-boot hijacking the log system, rather than a conflict between SLF4J an LOG4J2.
Note that I still see the same logging startup messages -- the OutputStreamManager is still shutting down. Speculation: this is normal behavior, possibly just shutting down the bootstrap logger that prints the log4j2 initialization process.
Versions:
log4j: 2.13.3
slf4j: 1.7.30
spring-boot: 2.2.7-RElEASE
I am trying to log in JSON format through log4j2.

Is there a dependency I am missing out or this some other problem? Please suggest possible things I can try for solving this problem. If you know a better solution to write logs in Logstash Json format you may suggest.
I suspect you are missing one of the Jackson dependencies.
You have jackson-core-asl, I think you need these three:
com.fasterxml.jackson.core:jackson-core:jar:2.6.3
com.fasterxml.jackson.core:jackson-databind:jar:2.6.3
com.fasterxml.jackson.core:jackson-annotations:jar:2.6.0
The ultimate source of truth for dependencies is the dependency tree of the Log4j 2 implementation module.
You may be able to get more details on the problem by setting <Configuration status="debug" ... in your configuration.
I'm using log4j2 (2.0.2) in a servlet 3.0 web application, running in Tomcat 8.0.12. I'm trying to use the weblookup to get the web app context path to use as part of the log file name. (We run the same war file under several different contexts using properties to configure it).
The log4j2.xml file includes
<RollingFile name="Web" fileName="/srv/dnsnet/logs/web-${web:contextPath}.logfile" filePattern="/srv/dnsnet/logs/web-${web:contextPath}-%d{yyyy-MM-dd}-%i.log.gz" append="true" immediateFlush="false">
<PatternLayout>
<Pattern>%d %-5p [%25.25t] %40.40c{3.} %15X{sysid} %m%n</Pattern>
</PatternLayout>
<Policies>
<TimeBasedTriggeringPolicy />
</Policies>
<DefaultRolloverStrategy max="8"/>
</RollingFile>
But the web:contextPath does not get resolved. I have got log4j-web-2.0.2.jar in my web app. I added some messages to the WebLookup class, and the problem is that the external context of the LoggerContext is null.
So I tried to see where the LoggerContext is created. The stack trace when the LoggerContext constructor is called is

But the ClassLoaderContextSelector always passes null for the external context. So it looks as though I'm missing something.
Can anyone suggest what I'm doing wrong, or missing? Do I have to specify a different ContextSelector?
You may have found a bug in log4j. I suspect it is the combination of Commons Logging and the WebLookup that does not work. Can you verify if this is the case (check if the WebLookup works if your application uses the log4j 2 API instead of Commons Logging) and file a bug report in the log4j2 Jira issue tracker?
