Architecture

logging-mv-integrations is an extension of the logging facility for Python used for TUNE Multiverse Integrations providing custom logger levels, format, and output.

UML logging-mv-integrations

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):
    """TUNE Logging Output ENUM
    """
    STDOUT = "stdout"
    STDOUT_COLOR = "color"
    FILE = "file"

Logging JSON Format

import logging
from logging_mv_integrations 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__})

Logging JSON Example Output

$ python3 examples/example_logging_json.py
