I've implemented a simple Java app that uses httpclient 5.1.3. I'm also using log4j2 (2.1.9) and have configured it emit log entries at the wire level. I know the log4j2 config is loaded because I can see my file appender working when I emit log messages from my app.
I don't understand why httpclient logging reports no appenders for org.apache.hc.client5.http.impl.classic.InternalHttpClient or for the asynch class if I change my app to use asynch protocol. Please help.
My log4j2 config:
<Appenders>
<Console name="Console">
<PatternLayout pattern="%d %-5level [%logger] %msg%n%xThrowable" />
</Console>
<File name="MyFile" fileName="c:/a/app.log">
<PatternLayout>
<Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
</PatternLayout>
</File>
</Appenders>
<Loggers>
<Logger name="org.apache.hc.client5.http" level="DEBUG">
<AppenderRef ref="Console"/>
</Logger>
<Logger name="org.apache.hc.client5.http.wire" level="DEBUG">
<AppenderRef ref="Console"/>
</Logger>
<Logger name="org.apache.hc.client5.http.impl.classic.InternalHttpClient" level="DEBUG">
<AppenderRef ref="Console"/>
</Logger>
<Root level="INFO">
<AppenderRef ref="MyFile" />
</Root>
</Loggers>
</Configuration>
I could sure use some help. Thanks.

log after migration just show hibernate log.
I don't know the main cause of this problem ,
can anyone help please
I have the following log4j2.xml config that I am using.
I have 2 issues :-
When my application runs up, I have nothing logged to either the
console or to mylog.log file by either of apache or springframework or
hibernate classes.
Classes within the package "com.foo.bar", I am able change the log
LEVEL via "level" attribute but the messages are only logged to
mylog.log file but nothing to the console
Any suggestions to above would be appreciated ?
thank you
Pete

It sounds like you have a misconfigured log.
Can you debug remotely and where you find use the logger to log something place a breakpoint. Inspect the logger and then you will find a location of where its picking up the log file from.
Also try providing a VM argument for log4j configuration (-Dlog4j.configuration)on start-up of your application.
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've been using log4j 2 (2.7) and it worked very well until I had to reinstall the IDE (Eclipse Neon J2EE edition).
Now I only works loggingto a log file but not to the console.
This is my log4j2.xml file:
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
</Console>
<File name="log" fileName="target/test.log" append="true">
<PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %class{36} %L %M %msg%xEx%n"/>
</File>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="Console"/>
</Root>
<Root level="TRACE">
<AppenderRef ref="log" />
</Root>
</Loggers>
The output to the log works perfectly, as I said.
Try declaring Root only once.
Example:
<Loggers>
<Root>
<AppenderRef ref="Console" level="error"/>
<AppenderRef ref="log" level="trace"/>
</Root>
</Loggers>
I agree with Sazzad 's answer: you can only have one root logger. I would suggest specifying a level on the root logger and override the level only on the AppenderRef that need it. So:
<Loggers>
<Root level="trace">
<AppenderRef ref="Console" level="error"/>
<AppenderRef ref="log"/>
</Root>
</Loggers>
Also, not sure if this was omitted just from the question or from the actual configuration file, but the configuration really should start with a <Configuration> and end with a </Configuration> element.
I am using Log4j 2 and I am using 4.0.4 version of datanucleus.
When I am running my app, then it is unable to generate datanucleus logs.
Datanucleus logs work fine with Log4j-1.x but when I switching Log4j-1.x to 2.x then I am unable to generate datanucleus logs.
Log4j2 XML is:

Kindly help me on this..
With Log4j 1.2 it is working for me, but when I try with Log4j 2.3 then other logs are generated except DataNucleus logs. Here are my dependencies:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.3</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.3</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-slf4j-impl</artifactId>
<version>2.3</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-web</artifactId>
<version>2.3</version>
</dependency>
If you facing problem using Log4j2 with datanucleus that is because datanucleus uses legacy org.apache.log4j.Logger api . To use both log4j2 and log4j 1.x you need to use bridge method .
configuring-log4j2-and-log4j-using-a-single-log4j2-xml-file
The first thing to try is to switch on Log4j 2 internal debugging. You can do this by replacing <Configuration status="FATAL" ... at the beginning of your config file with <Configuration status="TRACE".... This will display Log4j 2 internal debugging messages to the console. If you see any error here it may help you troubleshoot the issue.
A common issue is dependencies. Does your application use the Log4j-1.2 API? If so, you need to add the log4j-1.2-api-2.3.jar bridge to your dependencies. The bridge will route all calls by your application to log4j-1.2 to the Log4j 2 implementation.
Finally, make sure you remove the log4j-1.2.x.jar from your classpath!
