.. warning:: The :func:`fileConfig` function takes a default parameter,

``disable_existing_loggers``, which defaults to ``True`` for reasons of

backward compatibility. This may or may not be what you want, since it
|
||||
will cause any loggers existing before the :func:`fileConfig` call to
|
||||
be disabled unless they (or an ancestor) are explicitly named in the
|
||||
configuration. Please refer to the reference documentation for more
|
||||
information, and specify ``False`` for this parameter if you wish.
|

|

The dictionary passed to :func:`dictConfig` can also specify a Boolean
|
||||
value with key ``disable_existing_loggers``, which if not specified
|
||||
explicitly in the dictionary also defaults to being interpreted as
|
||||
``True``. This leads to the logger-disabling behaviour described above,

explicitly with a value of ``False``.

Loggers have the following attributes and methods. Note that Loggers are never
|
||||
instantiated directly, but always through the module-level function
|
||||
``logging.getLogger(name)``.
|
||||
``logging.getLogger(name)``. Multiple calls to :func:`getLogger` with the same
|
||||
name will always return a reference to the same Logger object.
|
||||
|
||||
The ``name`` is potentially a period-separated hierarchical value, like
|
||||
``foo.bar.baz`` (though it could also be just plain ``foo``, for example).
|
||||
Loggers that are further down in the hierarchical list are children of loggers
|
||||
higher up in the list. For example, given a logger with a name of ``foo``,
|
||||
loggers with names of ``foo.bar``, ``foo.bar.baz``, and ``foo.bam`` are all
|
||||
descendants of ``foo``. The logger name hierarchy is analogous to the Python
|
||||
package hierarchy, and identical to it if you organise your loggers on a
|
||||
per-module basis using the recommended construction
|
||||
``logging.getLogger(__name__)``. That's because in a module, ``__name__``
|
||||
is the module's name in the Python package namespace.
