Simple Json Logging Formatter

This is a fork of simple_json_logger, extracting the formatter into it's own project.

It formats the Python logging.Record into a JSON suitable for indexing engines like Logstash and AWS CloudWatch Logs.

Installation

pip install simple_json_log_formatter

Usage

Simply set the formatter in a log handler and add it to the current logger.

For example, to print the JSON logs to the current stream, set up the logger with the following:

import json, logging
from simple_json_log_formatter import SimpleJsonFormatter
handler = logging.StreamHandler()
handler.setFormatter(SimpleJsonFormatter(json.dumps))
logging.getLogger().addHandler(handler)
logging.getLogger().setLevel(logging.INFO)

And then simply call logging.info('TEST'). It should print something like this:

{"timestamp": "2017-09-08T17:01:26.408975", "line_number": 1, "function": "<module>", "module": "<input>", "level": "INFO", "path": "<input>", "msg": "TEST"}

Testing

python setup.py test

Compatibility

Python versions 2.7 and 3.4+ are supported.
