What are the different logging levels in Log4j2?
Log4j2 has several logging levels: TRACE, DEBUG, INFO, WARN, ERROR, and FATAL. Each level indicates the severity of the log message.
Can you explain what each level means?
Sure! TRACE is the most detailed, used for fine-grained debugging. DEBUG is for debugging information, INFO is for general information, WARN indicates a potential problem, ERROR is for error events, and FATAL is for very severe error events.
How do I configure these levels in my Log4j2 configuration file?
You can configure logging levels in the log4j2.xml or log4j2.properties file by setting the level attribute for your logger. For example, <Logger name="com.example" level="DEBUG">.
Is it possible to set different levels for different packages?
Yes, you can set different logging levels for different packages by defining multiple loggers in your configuration file, each with its own level.
