Uses a dotted notation, as used by python modules. If not L{None}, then the name of the module of the caller is used. @param source: The object which is emitting events via this logger; this is automatically set on instances of a class if this L{Logger} is an attribute of that class. @param observer: The observer that this logger will send events to.

In the above example, the namespace would be C{athing.Something}. Additionally, its source will be set to the actual object referring to the L{Logger}. In the above example, C{Something.log.source} would be C{Something}, and C{Something().log.source} would be an instance of C{Something}.

For example:: try: frob(knob) except Exception: log.failure("While frobbing {knob}", knob=knob) or:: d = deferredFrob(knob) d.addErrback(lambda f: log.failure("While frobbing {knob}", f, knob=knob)) This method is generally meant to capture unexpected exceptions in code; an exception that is caught and handled somehow should be logged, if appropriate, via L{Logger.error} instead. If some unknown exception occurs and your code doesn't know how to handle it, as in the above example, then this method provides a means to describe the failure in nerd-speak. This is done at L{LogLevel.critical} by default, since no corrective guidance can be offered to an user/administrator, and the impact of the condition is unknown. @param format: a message format using new-style (PEP 3101) formatting. The logging event (which is a L{dict}) is used to render this format string. @param failure: a L{Failure} to log. If L{None}, a L{Failure} is created from the exception in flight. @param level: a L{LogLevel} to use. @param kwargs: additional key/value pairs to include in the event.
