Documentation

pyfortified-logging

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

Install

pip install pyfortified_logging

Architecture

Function: get_logger()

def get_logger(
    logger_name,
    logger_version=None,
    logger_level=logging.INFO,
    logger_format=LoggingFormat.JSON,
    logger_output=LoggingOutput.STDOUT_COLOR,
    logger_handler=None
):

get_logger(): Parameters

Parameter Purpose
logger_name Return a logger with the specified name or, if name is None, return a logger which is the root logger of the hierarchy.
logger_version  
logger_format LoggingFormat
logger_output LoggingOutput
logger_handler logging.StreamHandler() or logging.FileHandler()

Logging Levels

Same Python logging levels, including one additional level NOTE.

Level Purpose
DEBUG Detailed information, typically of interest only when diagnosing problems.
NOTE Detailed information, request processing, for example, request using cURL.
INFO Confirmation that things are working as expected. [DEFAULT]
WARNING An indication that something unexpected happened, or indicative of some problem in the near future. The software is still working as expected.
ERROR Due to a more serious problem, the software has not been able to perform some function.
CRITICAL A serious error, indicating that the program itself may be unable to continue running.

Logging Format

Format Purpose
STANDARD Standard logging format.
JSON JSON logging format. [DEFAULT]
class LoggingFormat(object):
    """TUNE Logging Format ENUM
    """
    STANDARD = "standard"
    JSON = "json"

Logging Output

Output Purpose
STDOUT Standard Output to terminal
STDOUT_COLOR Standard Output using colored terminal
FILE Standard Output to file created within ./tmp/log_<epoch time seconds>.json.
class LoggingOutput(object):
    """Logging Format ENUM
    """
    STDOUT = "stdout"
    STDOUT_COLOR = "color"
    FILE = "file"

Logging JSON Format

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

log = get_logger(
    logger_name=__name__,
    logger_version=__version__,
    logger_format=LoggingFormat.JSON,
    logger_level=logging.NOTE
)

log.info("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__})
