A standardised logging configuration I use for a few things.

Quickstart

1. Install this package with optional extras:

   pip install python-logsy[fluent,sentry]
   

2. Import and configure. This package has three logging handlers available in the default configuration. All are relatively self-explanatory except that the fluent handler logs to a Fluentd or Fluent Bit instance and requires the fluent dependencies to be installed via the optional extras. Furthermore, the file handler uses logging.handlers.RotatingFileHandler. Log files will rollover at 100 megabytes when using the file handler.

   import logging
   
   import logsy
   
   config = {
       'loggers': {
           'app': {
               'handlers': ['console', 'fluent', 'file'],
               'level': 'INFO',
               'propagate': True,
           },
       },
   }
   logsy.init(
       config,
       tag='apps.myapp', # Also used as the Fluent tag (routing)
       fluent_host='localhost',
       environment='production',
       release='2.1.1-beta',
   )
   

3. A complete example of init; including setup for Sentry:

   logsy.init(
       config,
       tag='apps.myapp', # Also used as the Fluent tag (routing)
       replace_config=False,
       fluent_host='localhost',
       fluent_port=24224, # default
       async_fluent=True, # default
       environment='debug',
       debug=True, # default is False
       release='2.1.1-beta',
       level=logging.INFO, # default
       sentry_config={
           'dsn': 'fake-dsn-string',
           'traces_sample_rate': 1.0, # default
       },
   )
   

4. Log as per usual:

   import logging
   
   logger = logging.getLogger(__name__)
   logger.info('Testing')
   

5. If needed, replace the default logging config with your own:

   config = {
       'version': 1,
       'disable_existing_loggers': False,
       'formatters': {}, # incomplete
       'handlers': {}, # incomplete
   }
   logsy.init(
       config,
       replace_config=True,
       tag='apps.myapp',
       fluent_host='localhost',
       fluent_port=24224, # default
       environment='debug',
       debug=True, # default is False
       release='2.1.1-beta',
       level=logging.INFO, # default
   )
