A sample application using Graylog.
Built to open standards, Graylog’s connectivity and interoperability seamlessly collects, enhances, stores, and analyzes log data. – Graylog
So we could hook Graylog into the standard logging library in Python, but we're going to adhere to The 12 Factor App as our guiding principle.
A twelve-factor app never concerns itself with routing or storage of its output stream. It should not attempt to write to or manage logfiles. Instead, each running process writes its event stream, unbuffered, to stdout. During local development, the developer will view this stream in the foreground of their terminal to observe the app’s behavior.
Enter, the logging driver
It's as easy as:
$ docker-compose up -d
You can find the Graylog UI at: http://localhost:9000
Navigate to the Graylog UI, under the System/Inputs directory create an input GELF UDP then create an extractor on the message field JSON.
