format to specify our desire log format.
Let's add a new line to logging.properties with property key Color escape codes can be selected based on the log records level, by adding parameters to the format string: logcolor: Return the color associated with the records level. The good thing, we don't have to learn new formatting specifiers here, as specification is fully supported. The first argument 'format' can be customized in the logging.properties or by a command line option or can be set programmatically. The default formatter, SimpleFormatter, formats the output by using following method call: String.format(format, date, source, logger, level, message, thrown) Provides the class readablelogformatter.ReadableFormatter to be used with Python's logging: import logging from readablelogformatter import ReadableFormatter log logging.

In this tutorial, we will learn how to modify the default log format. This handler, by default uses SimpleFormatter to format logs. The default handler, ConsoleHandler, sends log records to System.err (the available command line console). The complete default configuration file can be found at the JDK/JRE installation directory: JAVA_HOME/jre/lib/logging.properties. Some formatters (such as the XMLFormatter) need to wrap head and tail strings around a set of formatted records. The Formatter takes a LogRecord and converts it to a string. Typically each logging Handler will have a Formatter associated with it. By default Java Util logging (JUL) uses following configurations (JDK 8): A Formatter provides support for formatting LogRecords.
