Description

Simplifies logging for systemd

Requires Python 3.6+

• No need to compile (pure Python), uses libsystemd.so.
• Simplified configuration.
• Just logging. Nothing more.

Usage

import logging

from systemdlogging.toolbox import init_systemd_logging

# This one line in most cases would be enough.
# By default it attaches systemd logging handler to a root Python logger.
init_systemd_logging()  # Returns True if initialization went fine.

# Now you can use logging as usual.
logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)

logger.debug('My debug message')

try:
    raise ValueError('Log me please')

except ValueError:
    # Additional context can be passed in extra.context.
    logger.exception('Something terrible just happened', extra={
        'message_id': True,  # Generate message ID automatically.
        'context': {
            'FIELD1': 'one',
            'FIELD2': 'two',
        }
    }, stack_info=True)
