log4j2

I'm use to RollingFileAppender on normal log4j. Now I'm switching to log4j2 , and cannot get the appender to work. The File appender below works as expected. But the logging file for RollingFile is never created. Why? <?xml version="1.0" encoding="UTF-8"?> <Configuration> <Appenders> <File name="FILE" fileName="c:/logs.log"> <PatternLayout pattern="%d %p %c: %m%n" /> </File> <RollingFile name="ROLLING" fileName="c:/logsroll.log"> <PatternLayout pattern="%d %p %c: %m%n"/> <Policies> <TimeBasedTriggeringPolicy /> <SizeBasedTriggeringPolicy size="0.001 MB"/> </Policies> <DefaultRolloverStrategy

I need to log events into the syslog. I use lo4j2 and the syslog appender. My appenders block in log4j2.xml looks like this: <appenders> <Console name="Console" target="SYSTEM_OUT"> <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/> </Console> <Syslog name="syslog" host="localhost" port="514" protocol="UDP" charset="ISO-8859-1"> </Syslog> <RollingFile name="AppLog" fileName="/var/log/app.log" filePattern="/var/log/$${date:yyyy-MM}/app-%d{MM-dd-yyyy}-%i.log.gz"> <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/> <Policies>

I'm trying to use Log4j2 to print the spring logs into a file and console. I guess it is a problem in my Log4j2 configuration. I have not been able to get it working. I have this configuration in my log4j2.xml file: <?xml version="1.0" encoding="UTF-8"?> <configuration name="defaultConfiguration" status="warn" strict="true" monitorInterval="5"> <properties> <property name="patternlayout">%d{ISO8601} [%t] %-5level %logger{36} - %msg%n%throwable{full}</property> <property name="filename">${env:MY_ROOT}/logs/mylog.log</property> <property name="filenamePattern">${env:MY_ROOT}/logs/mylog-%d{yyyy

How do I configure log4j 2.3 with console appender pure programmatically (no configuration files of any format)? Basically I'm looking for 2.x version of this 1.x code . In my classes I would then use private static final Logger logger = LogManager.getLogger(); // // some method logger.debug(someString); Without any configuration I'm (as expected) facing ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. While usage of configuration files seems to be properly documented , I couldn't find a good example of a bare-bone code

I have a new application that is being written using log4j2, to take advantage of some of its new features. One of the libraries it uses is a bit older and was built with log4j 1.x. I'm having a problem where the new code in the application writes to the log, but the code in the old library does not write to the log. I even have one class which is a subclass of something in the old library and is also called by code in the old library, and this code also will not write to the log. I have configured the application to use log4j2 version 2.0.2, and I explicitly excluded log4j when referencing
