How to find out which Log4j configuration is loaded?
We’re using Log4j (via Slf4j) for logging.
Our log4j configuration is rather simple:
<?xml version="1.0" encoding="UTF-8"?> <Configuration> <Appenders> <Console name="Console"> <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/> </Console> </Appenders> <Loggers> <Root level="INFO"> <AppenderRef ref="Console"/> </Root> <Logger name="net.sf.jsi.rtree.RTree" level="INFO"> <AppenderRef ref="Console"/> </Logger> </Loggers> </Configuration> Note that root logger is set to INFO.
However, we’re getting a huge amount of DEBUG logs from a third-party library (net.sf.jsi). Logs we’re absolutely not interested in. My guess is that there’s a different Log4j configuration on the classpath somewhere which gets picked up and sets root logger to DEBUG.
My question is, how could I found which configuration is actually loaded and used by log4j?
Update:
I have seen this "possible duplicate". However, the answer which suggests to use -Dlog4j.debug does not work for me.
I’ve added -Dlog4j.debug to the VM arguments. I only get:
DEBUG StatusLogger org.slf4j.helpers.Log4jLoggerFactory is not on classpath. Good! DEBUG StatusLogger Using ShutdownCallbackRegistry class org.apache.logging.log4j.core.util.DefaultShutdownCallbackRegistry WARN StatusLogger Multiple logging implementations found: Factory: org.apache.logging.log4j.core.impl.Log4jContextFactory, Weighting: 10 Factory: org.apache.logging.slf4j.SLF4JLoggerContextFactory, Weighting: 15 Using factory: org.apache.logging.slf4j.SLF4JLoggerContextFactory which is not enough info for me.
