What are the different logging levels in Logback?
Logback supports 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 level, 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 Logback configuration file?
You can configure logging levels in the logback.xml
file using the <logger>
tag. For example, <logger name="com.example" level="DEBUG"/>
sets the logging level to DEBUG for the specified package.
Is it possible to change logging levels at runtime?
Yes, Logback allows you to change logging levels at runtime using JMX or by modifying the configuration file and reloading it.
