JSON Logging Library with Python

Project Description

Project JSONkLog

The goal of this library is to provide a simple formatter, and handlers for standard python logging libraries to deal with JSON output in a sort of “set it and forget it” methodology that python logging currently provides.

Formatters :

Currently there are two formatters:

  • JSONFormatter
  • JSONFormatterSimple

Each of the formatters processes the standard python logging messages into JSON however the “Simple” library provides a limited output including only 3 key elements and the mysterious 4th element “Extras”

Please note that “extras” as a dictionary requires the content to be nested under the “extra” key within the dictionary

For examples, please see example_formatter.py within the source tree at:

Handlers :

Currently there are two handlers, which require JSONFormatter, or JSONFormatterSimple to have been used :

  • MongoDBHandler
  • ElasticSearchHandler

Each of the handlers can process the standard JSON messages from the included JSON formatting libraries, and can have different destinations specified as follows:

MongoDBHandler :

This handler speaks MongoDB (using ‘pymongo’), and can take the following arguments:

  • host - The destination host / ip of the MongoDB server
  • port - The destination port of the MongoDB server
  • db - The destination database to send messages to
  • collection - The destination collection to send messages to

ElasticSearchHandler :

This handler speaks ElasticSearch (using ‘requests’), and can take the following arguments:

  • host - The destination host / ip of the ElasticSearch server
  • port - The destination port of the ElasticSearch server
  • index - The destination index to send messages to
  • doc_type - The destination doc_type to send messages to

Note :

To format your JSON into “human readable whatsits” ensure your handler outputs to stdout, and then pipe through the node-json library (‘json’), installed as per:

  • npm install -g json

This is not a requirement, but rather what I’m using to do my testing ;)
