Python logging logstash handler

sag_py_logging_logstash

Python Logstash Async is an asynchronous Python logging handler to submit log events to a remote Logstash instance. It based on open source library, see the documentation http://python-logstash-async.readthedocs.io/en/latest/. In this version transporter is limited to HTTPTransport, according to Logstash intern installation requirements.

Unlike most other Python Logstash logging handlers, this package works asynchronously by collecting log events from Python's logging subsystem and then transmitting the collected events in a separate worker thread to Logstash. This way, the main application (or thread) where the log event occurred, doesn't need to wait until the submission to the remote Logstash instance succeeded.

This is especially useful for applications like websites or web services or any kind of request serving API where response times matter.

Usage

Example::

from logstash_async.handler import AsynchronousLogstashHandler
from logstash_async.formatter import LogstashFormatter
import logging

logstash_handler = AsynchronousLogstashHandler(
    host='my_host',
    port=123,
    username='my_user',
    password='my_password',
    index_name = 'my_index')
logstash_formatter = LogstashFormatter( extra_prefix='',
extra={'customer': "name", 'ap_environment': "local"})
logstash_handler.setFormatter(logstash_formatter)

logging_handlers = []
logging_handlers.append(logstash_handler)

logging.basicConfig(
level="INFO",
format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
handlers=logging_handlers)

logging.getLogger().info("Logging Message", extra = {'new_field':"value"})
