log4j2

I'm trying to use log4j2 OSGi bundles, but it seems log4j2 api cannot find log4j2 core in an OSGi environment. I'm continuously getting the following exception : ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console I found the same exception discussed in few places but still I could not figure out this issue. Isuspect I'm getting this issue because log4j2 api cannot find the log4j-provider.properties inside the META-INF directory of log4j2 core. Is there any clue why I'm getting this exception and

Im using log4j2 with following dependencies: <!-- LOG4J2 --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-api</artifactId> <version>2.0-rc1</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>2.0-rc1</version> </dependency> <dependency> <groupId>com.lmax</groupId> <artifactId>disruptor</artifactId> <version>3.0.1</version> </dependency> Log4j2.xml content: <?xml version="1.0" encoding="UTF-8"?> <Configuration status="OFF"> <Appenders> <Console name="CONSOLE" target="SYSTEM_OUT">

I want to create day dependent logfiles with log4j2 : <RollingFile name="APP" fileName="application-%d{yyyy-MM-dd}.log" /> Resulting logfile name: application-%d{yyyy-MM-dd}.log , the timestamp is not replaced. Why? The pattern should not be given in the attribute "fileName" rather you have to specify the pattern in the attribute "filePattern" as like below. <RollingFile name="RollingFile" fileName="${log-path}/filename.log" filePattern="${log-path}/filename-%d{yyyy-MM-dd}-%i.log" > ... ... </RollingFile> The "%i" is the counter that will be automatically incremented in rollover. Hope this

in log4j I could specify a class in the properties file to log at the debug level like this: log4j.logger.com.mycompany.mypackage.ClassName=DEBUG How do I do this in log4j2? Note I still need to use the new property file (not xml or json). TIA As the log4j2 configuration documentation states As of version 2.4, Log4j now supports configuration via properties files. Note that the property syntax is NOT the same as the syntax used in Log4j 1. It then provides a substantial example for all types of configuration elements. Concerning your question, you need to specify your loggers in a loggers

I am trying to follow the example here https://www.endgame.com/blog/storm-metrics-how here is my storm.yaml storm.zookeeper.servers: - localhost supervisor.slots.ports: - 6700 - 6701 - 6702 - 6703 - 6704 nimbus.host: localhost ui.port: 8080 ui.host: localhost storm.log.dir: /path/to/storm/logdir topology.max.spout.pending: 5000 I tried running the topology in local and cluster mode. the metrics.log file is created at the location /path/to/storm/logdir but the file is empty! am i missing some configuration? The problem is with the current log4j2 setup of Metrics in Storm and the fix is a little

I'm trying to use log4j 2 logger in my Spark job. Essential requirement: log4j2 config is located outside classpath, so I need to specify its location explicitly. When I run my code directly within IDE without using spark-submit , log4j2 works well. However when I submit the same code to Spark cluster using spark-submit , it fails to find log42 configuration and falls back to default old log4j. Launcher command ${SPARK_HOME}/bin/spark-submit \ --class my.app.JobDriver \ --verbose \ --master 'local[*]' \ --files "log4j2.xml" \ --conf spark.executor.extraJavaOptions="-Dlog4j.configurationFile

I want to create a custom log4j2 rolling file appender. I need to create this custom appender because I want to wrap the log4j log event with some information unique to my application. Such as userId, hosted application name. I have a class which extends Log4jLogEvent implements LogEvent. This class has information that I need to wrap with the log event. Please see this code : public class CustomLogEvent extends Log4jLogEvent implements LogEvent { private String userId; private String applicationName; private static final long serialVersionUID = 1L; public CustomLogEvent(String loggerName,

I am trying to create a custom appender for log4j 2.0, but am having issues getting my log4j configuration to recognize the appender. I know log4j 2.0 doesnt support packages in configuration attributes. So I tried, as suggested here , running the code with plain javac but even then it gives this error: 2015-03-11 18:47:35,281 ERROR Error processing element Test: CLASS_NOT_FOUND 2015-03-11 18:47:35,307 ERROR Unable to locate appender test1 for logger Here is my custom appender: @Plugin(name = "Test", category = "Core", elementType = "appender", printObject = true) public class TestAppender

How can we write a simple log4j2.xml file with different levels of logs going into different files? For example we have error logs any info logs I need to push all error log messages into one log file and all info log messages into another file. I want that info message in InfoController.log file and error message in LoginController.log file How can i do it? Finally got the answer by doing this i got the logs in different files. <Loggers> <logger name="com.mvc.login" level="info" additivity="false"> <AppenderRef ref="LoginController" level="error"/> <AppenderRef ref="InfoController" level=
