Extension to Python `logging` functionality.

Project description


This Python project is an extension of the native Python component logging providing more robust message formatting for standard and JSON logging output, and in addtion allowing for extra content populated as dictionaries.

Important Note

This Python project is a refactoring of logging-mv-integrations for the purpose of general usage intent.

Work In Progress

The following still needs to be performed for this Python project:

  • Unit-testing: This project will be switching over to using Python native Unit testing framework unittest.
  • More concise documentation is required.
  • Travis CI
  • Badges

    FILE = "file"

Logging JSON Format

import logging
from logging_fortified import (LoggingFormat, get_logger, __version__)

log = get_logger(
)"logging: info", extra={'test': __name__})
log.note("logging: note", extra={'test': __name__})
log.debug("logging: debug", extra={'test': __name__})
log.warning("logging: warning", extra={'test': __name__})
log.error("logging: error", extra={'test': __name__})
log.critical("logging: critical", extra={'test': __name__})
log.exception("logging: exception", extra={'test': __name__})
