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 -->

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
P.S. - here is my pom.xml:

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 only get this on the console:
13:08:18.379 [main] ERROR log4.prueba - This is Error
13:08:18.381 [main] FATAL log4.prueba - This is Fatal
I dont get a file or all the other levels.
What I am doing wrong?
My directory looks like this:
projectFolder/src/log4/prueba.java
projectFolder/src/log4j.properties
The code:
package log4;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
public class prueba {
private static Logger logger = LogManager.getLogger(prueba.class);
public static void main( String[] args )
{
logger.debug("This is Debug");
logger.info("This is Info");
logger.warn("This is Warn");
logger.error("This is Error");
logger.fatal("This is Fatal");
}
}
And the properties file look like this:
# Root logger option
log4j.rootLogger=DEBUG, file, stdout
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\logging.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p
%c{1}:%L - %m%n
# Direct log messages to 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 2 also supports configuration in properties files, but be aware:
the file needs to be called log4j2.properties
the configuration syntax is different from the Log4j 1.2 syntax (the configuration in the question uses the old Log4j 1.2 syntax, Log4j 2 will not understand this)
The Log4j 2 user manual has mostly XML examples, so many people find it easier to use the XML configuration syntax. (Again, the config file should be named log4j2.xml, Log4j 2 will ignore log4j.xml.)

I am trying to add log4j to my web application to record the exchange between the server and the client so I added the dependency in my pom.xml:
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
and I created the log4j.proporties:

log4j.rootLogger=INFO, file
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
#Redirect to Tomcat logs folder

and the following is my code :
static final Logger logger = Logger.getLogger(hellologger.class);
public static void main(String[] args) {
String log4JPropertyFile = "C:\\Users\\xxxx\\Desktop\\log4j.properties";
Properties p = new Properties();
try {

PropertyConfigurator.configure(p);
logger.info("Wow! I'm configured!");
} catch (IOException e) {

any idea how to fix this problem ?!!!!
You can go through this tutorial on log4j .
The properties file and pom.xml files are explained properly .
logs generated are like this :

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.
