log4mongo-python is mongo database handler for python logging, part of log4mongo.org project. log4mongo-python is using pymongo driver - http://github.com/mongodb/mongo-python-driver
- python 2.7+
- pymongo 2.8+
- mongo database
For more information see debian_requirements.txt and requirements.txt files.
Example handler python configuration:
import logging
from log4mongo.handlers import MongoHandler
logger = logging.getLogger('test')
logger.addHandler(MongoHandler(host='localhost'))
logger.warning('test')
It is possible to decorate you document with contextual information. There are tow approaches.
1.) approach
import logging
from log4mongo.handlers import MongoHandler
handler = MongoHandler(host='localhost')
logger = logging.getLogger('test')
logger.addHandler(handler)
logging.LoggerAdapter(logger, {'ip': '127.0.0.1'}).info('test')
2.) approach
import logging
from log4mongo.handlers import MongoHandler
handler = MongoHandler(host='localhost')
logger = logging.getLogger('test')
logger.addHandler(handler)
logger.info('test', extra={'ip': '127.0.0.1'})
As you can see, second approach is more straightforward and there is no need to use LoggerAdapter.
Capped collections are fixed-size collections that support high-throughput operations that insert, retrieve, and delete documents based on insertion order. Capped collections work in a way similar to circular buffers: once a collection fills its allocated space, it makes room for new documents by overwriting the oldest documents in the collection.
Before switching to capped collections, read this document please: http://docs.mongodb.org/manual/core/capped-collections/
This behaviour is disabled by default. You can enable this behaviour in constructor with capped=True:
import logging from log4mongo.handlers import MongoHandler handler = MongoHandler(host='localhost', capped=True)
** Tested on evnironment **
- LinuxMint 15 Olivia 64-bit
- python 2.7.4
- pymongo >2.8.3
- mongod - db version v3.0.7
- python unittest
Running tests
Before you run the test you must start mongo database. You will do so by this command:
$ mongod --dbpath /tmp/
To run the test run command:
$ python test.py $ python setup.py test
