.. _how_to_log:
Logging
=======
Quart has a standard Python logger sharing the same name as the
``app.name``. To use it, simply make use of
:attr:`~quart.app.Quart.logger`, for example:
.. code-block:: python
app.logger.info('Interesting')
app.logger.warning('Easy Now')
Configuration
-------------
The Quart logger is not created until its first usage, which may occur
as the app is created. These loggers on creation respect any existing
configuration. This allows the loggers to be configured like any other
python logger, for example
.. code-block:: python
from logging.config import dictConfig
dictConfig({
'version': 1,
'loggers': {
'quart.app': {
'level': 'ERROR',
},
},
})
Disabling/removing handlers
---------------------------
The handler :attr:`~quart.logging.default_handler` attached to the
quart logger can be removed like so,
.. code-block:: python
from logging import getLogger
from quart.logging import default_handler
getLogger(app.name).removeHandler(default_handler)
