See details inhttp://tobrunet.ch/2013/09/logstash-1-2-0-upgrade-notes-included/andhttps://logstash.jira.com/browse/LOGSTASH-675Addedversionparameter. Available values: 1 (Logstash 1.2.x version format), 0 - default (previous version).InstallationUsing pip:pip install python-logstashUsageLogstashHandleris a custom logging handler which sends Logstash messages using UDP.For example:import logging
import logstash
import sys

host = 'localhost'

test_logger = logging.getLogger('python-logstash-logger')
test_logger.setLevel(logging.INFO)
test_logger.addHandler(logstash.LogstashHandler(host, 5959, version=1))
# test_logger.addHandler(logstash.TCPLogstashHandler(host, 5959, version=1))

test_logger.error('python-logstash: test logstash error message.')
test_logger.info('python-logstash: test logstash info message.')
test_logger.warning('python-logstash: test logstash warning message.')

# add extra field to logstash message
extra = {
    'test_string': 'python version: ' + repr(sys.version_info),
    'test_boolean': True,
    'test_dict': {'a': 1, 'b': 'c'},
    'test_float': 1.23,
    'test_integer': 123,
    'test_list': [1, 2, '3'],
}
test_logger.info('python-logstash: test extra fields', extra=extra)When usingextrafield make sure you don’t use reserved names. FromPython documentation.“The keys in the dictionary passed in extra should not clash with the keys used by the logging system. (See theFormatterdocumentation for more information on which keys are used by the logging system.)”To use the AMQPLogstashHandler you will need to install pika first.pip install pikaFor example:import logging
import logstash

test_logger = logging.getLogger('python-logstash-logger')
test_logger.setLevel(logging.INFO)
test_logger.addHandler(logstash.AMQPLogstashHandler(host='localhost', version=1))

test_logger.info('python-logstash: test logstash info message.')

}Example Logstash ConfigurationExample Logstash Configuration (logstash.conf) for Receiving Events from python-logstash is:input {
  udp {
    port => 5959
    codec => json
  }
}
output {
  stdout {
    codec => rubydebug
  }
}For TCP input you need to change the logstash’s input totcpand modify django log handler’s class tologstash.TCPLogstashHandler
