jsonlog

A set of Python modules for working with structured JSON logs.

• jsonlog provides a JSON formatter for Python's logging module.
• jsonlog-cli provides a command line tool for converting JSON logs into human readable output.

The jsonlog module

You can use jsonlog as a drop-in replacement for logging:

import jsonlog

jsonlog.warning("Hello world.")

{"timestamp": "2019-06-21T19:06:25.285730", "level": "WARNING", "name": "root", "message": "Hello world."}

See the jsonlog README for documentation and examples.

The jsonlog cli

Pipe line-delimited JSON into the jsonlog CLI:

python jsonlog-cli/docs/example.py | jsonlog

timestamp='2020-06-15T13:27:41.909782' name='example' message='debug level log message'
timestamp='2020-06-15T13:27:41.909882' name='example' message='info level log message'
timestamp='2020-06-15T13:27:41.909940' name='example' message='warning level log message'
timestamp='2020-06-15T13:27:41.909990' name='example' message='error level log message'
timestamp='2020-06-15T13:27:41.910040' name='example' message='error level log message with traceback'

    Traceback (most recent call last):
