+
+Configuring Logging
+===================
+
+Jupyter Server (and Jupyter Server extension applications such as Jupyter Lab)
+are Traitlets applications.
+
+By default Traitlets applications log to stderr. You can configure them to log
+to other locations e.g. log files.
+
+Logging is configured via the ``logging_config`` "trait" which accepts a
+:py:func:`logging.config.dictConfig` object. For more information look for
+``Application.logging_config`` in :ref:`other-full-config`.
+
+
+Examples
+--------
+
+.. _configurable_logging.jupyter_server:
+
+Jupyter Server
+^^^^^^^^^^^^^^
+
+A minimal example which logs Jupyter Server output to a file:
+
+.. code-block:: python
+
+   c.ServerApp.logging_config = {
+       'version': 1,
+       'handlers': {
+           'logfile': {
+               'class': 'logging.FileHandler',
+               'level': 'DEBUG',
+               'filename': 'jupyter_server.log',
+           },
+       },
+       'loggers': {
+           'ServerApp': {
+               'level': 'DEBUG',
+               'handlers': ['console', 'logfile'],
+           },
+       },
+   }
+
+.. note::
+
+   To keep the default behaviour of logging to stderr ensure the ``console``
+   handler (provided by Traitlets) is included in the list of handlers.
+
+.. warning::
+
+   Be aware that the ``ServerApp`` log may contain security tokens. If
+   redirecting to log files ensure they have appropriate permissions.
+
+
+.. _configurable_logging.extension_applications:
+
+Jupyter Server Extension Applications (e.g. Jupyter Lab)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+An example which logs both Jupyter Server and Jupyter Lab output to a file:
+
+.. note::
+
+   Because Jupyter Server and its extension applications are separate Traitlets
+   applications their logging must be configured separately.
+
+.. code-block:: python
+
+   c.ServerApp.logging_config = {
+       'version': 1,
+       'handlers': {
+           'logfile': {
+               'class': 'logging.FileHandler',
+               'level': 'DEBUG',
+               'filename': 'jupyter_server.log',
+               'formatter': 'my_format',
+           },
+       },
+       'formatters': {
+           'my_format': {
+               'format': '%(asctime)s %(levelname)-8s %(name)-15s %(message)s',
+               'datefmt': '%Y-%m-%d %H:%M:%S',
+           },
+       },
+       'loggers': {
+           'ServerApp': {
+               'level': 'DEBUG',
+               'handlers': ['console', 'logfile'],
+           },
+       },
+   }
+
+   c.LabApp.logging_config = {
+       'version': 1,
+       'handlers': {
+           'logfile': {
+               'class': 'logging.FileHandler',
+               'level': 'DEBUG',
+               'filename': 'jupyter_server.log',
+               'formatter': 'my_format',
+           },
+       },
+       'formatters': {
+           'my_format': {
+               'format': '%(asctime)s %(levelname)-8s %(name)-15s %(message)s',
+               'datefmt': '%Y-%m-%d %H:%M:%S',
+           },
+       },
+       'loggers': {
+           'LabApp': {
+               'level': 'DEBUG',
+               'handlers': ['console', 'logfile'],
+           },
+       },
+   }
+
+.. note::
+
+   The configured application name should match the logger name
+   e.g. ``c.LabApp.logging_config`` defines a logger called ``LabApp``.
+
+.. tip::
+
+   This diff modifies the example to log Jupyter Server and Jupyter Lab output
+   to different files:
