===Logger===

Most frameworks support the notion of a Logger. A Logger is an object that allows the application to log data without regard to where the data is actually logged. The application logs a message in the form of an object or andan object and exception. When a Logger is created, it is given a name or an identifier. When logging a message, it is logged at a certain level or priority.

====Name====

A logger has a name. The name is usually hierarchical, with periods (.) separating the levels. A common naming scheme is to use the name of the class or package that is doing the loggings. Both [[log4j]] and the Java API supported defining Handlers higher up the hierarchy.
