mongolog 0.2.0

Installation

Install from PyPI:

$ python -m pip install mongolog

Or install the latest source checkout:

$ python -m pip install git+https://github.com/puentesarrin/mongodb-log.git

MongoDB setup

Create a collection for log records. A capped collection is useful for log data because older records automatically roll out when the collection reaches its configured size:

> use mongolog
> db.createCollection('log', {capped: true, size: 100000})

Usage

Add MongoHandler to any standard Python logger:

import logging

from mongolog import MongoHandler


log = logging.getLogger('demo')
log.setLevel(logging.DEBUG)
log.addHandler(MongoHandler.to('log', db='mongolog'))

log.debug('Some message')

Structured messages remain queryable in MongoDB because MongoLog stores the original record.msg value:

log.info({'address': '340 N 12th St', 'state': 'PA', 'country': 'US'})

Development

Install development tools and run the test suite with tox:

$ python -m pip install -e ".[dev]"
$ tox

The tests use a real MongoDB server. By default they connect to localhost:27017. Override that with MONGO_HOST and MONGO_PORT:

$ MONGO_HOST=localhost MONGO_PORT=27017 tox

Run the same tests directly with unittest:

$ python -m unittest discover -s tests -p 'test_*.py'

To test against specific Python interpreters installed on your machine:

$ tox -e py39,py310,py311,py312,py313,py314

Releases

CI builds the source distribution and wheel on every push. Tag pushes publish to PyPI through GitHub Actions Trusted Publishing using the pypi environment.
