Question

What are the different logging levels in Log4j Loggers?

Answer 1

Hello @Pankaj, Log4j Loggers have following levels of logging:

• Trace: Designates finer-grained informational events than the DEBUG.

• Debug: Designates fine-grained informational events that are most useful to debug an application.

• Info: Designates informational messages that highlight the progress of the application at coarse-grained level.

• Warn: Designates potentially harmful situations.

• Error: Designates error events that might still allow the application to continue running.

• Fatal: Designates very severe error events that will presumably lead the application to abort.

Log levels have following order:

TRACE < DEBUG < INFO < WARN < ERROR < FATAL.
