The architecture of
Logging Toolkit for
Java includes loggers,
handlers, filters, and
formatters. Loggers generate
the data to be logged; there
are message loggers for end
users and administrators and
trace loggers for
developers. Handlers process
the event data generated by
the loggers and correspond
to a physical device, such
as a console, file, or
socket. Filters control
which log records are
written to the output
devices controlled by the
Handlers. Formatters present
event data in a desired
format and recognize
specific types of events;
multiple formatters may be
attached to a handler, which
allows the handler to
process diverse event types.
