Modifying the runtime log levels via the administration console (changes made here will not persist across restarts). Remember, each message on the log is prefixed by the level of the message.

To define a custom log level in code, use the level.forname() method. Log4j provides you configuration file based level setting which sets you free from changing the source code when you want to change the debugging level.

Therefore, in order to see the fine (, finer or finest) output, you need to set the default value of the root logger and its consolehandler to level.fine as follows: In log4j, levels are instance of org.apache.log4j.level class. Solution here below we will see some steps that allows us to configure different output files when using apache commons logging and log4j.

What is a logging level. Sikorsky, robert shaw, brent sprecher, richard hurst, brad marlborough see also: Log4j will inspect log4j.configurationfile system property to determine log4j2 configuration file.

For example, if logger level is info then debug logs will not be printed but warn logs will be printed because of higher priority.
