Sending logs to Graylog
To send logs to Graylog from Python, you can use Graypy (https://github.com/severb/graypy), which converts Python logs to the Graylog Extended Log Format (GELF) (http://docs.graylog.org/en/latest/pages/gelf.html).
Graypy will send the logs via UDP by default, but can also send them via AMQP if you need to be 100% sure that every log makes it to Graylog.
In most cases, UDP is good enough for centralizing logs. But unlike TCP, some packets may be dropped, and you won't know it. If your logging strategy needs more guarantee, a RabbitMQ-based transport will be more reliable.
Plugging graypy consists of using the provided handler in place of one of the built-in handlers:
handler = graypy.GELFHandler('localhost', 12201) ...
