ZeroMQLog - A ZeroMQ Pub/Sub Logging Handler for Python

A logging handler for Python that publishes log messages using zeromq's pub/sub system. You can use this to read or respond to streaming log data in real time. If you are using sub-watcher then the messages can be redirected back to redis or syslog as needed with all sorts of filter goodness.

This project and it's layout and details were inspired by Jed Parsons and python-redis-log (currently hosted on GitHub).

Installation

The current stable release

pip install python-zeromq-log

or

easy_install python-zeromq-log

The latest from github

git clone git://github.com/rbucker881/python-zeromq-log.git
cd python-zeromq-log
python setup.py build
python setup.py install --prefix=$HOME  # for example

Requirements

• redis
• The Python redis client by Andy McCurdy
• simplejson

Usage

>>> from zeromqlog import handlers, logger
>>> l = logger.ZeroMQLogger('my.logger')
>>> l.addHandler(handlers.ZeroMQHandler.to("my:channel"))
>>> l.info("I like chocolate cake")
>>> l.error("Belts?", exc_info=True)

ZeroMQ (rbucker881/sub-watcher) clients subscribed to my:channel will get a json log record like the following (sent from function foo() in file test.py:

{ username: 'richard',
  args: [],
  name: 'my.logger',
  level: 'info',
  line_no: 6,
  traceback: null,
  filename: 'qa.py',
  time: '2011-06-02T14:50:08.237052',
  msg: 'losing',
  funcname: 'bar',
  hostname: 'frosty.local' }

If an exception is raised, and exc_info is True, the log will include a formatted traceback in traceback.

The date is stored as an ISO 8601 string in GMT.
