Logstash Plugin

This is a plugin for Logstash.

It is fully free and fully open source. The license is Apache 2.0, meaning you are pretty much free to use it however you want in whatever way.

Documentation

Logstash provides infrastructure to automatically generate documentation for this plugin. We use the asciidoc format to write documentation so any comments in the source code will be first converted into asciidoc and then into html. All plugin documentation are placed under one central location.

Ruby development environment setup

Yet another step-by-step guide to setting up a Ruby developement environment. Setting up a proper Ruby development environment involves setting up a Ruby Version Manager and Gem dependencies isolation.

rbenv setup

You should never rely on your system installed Ruby but use a Ruby Version Manager. There are 2 main tools for this, RVM and rbenv. This is a guide for rbenv which I prefer for its simple, minimalist, less intrusive approach and its rich plugins ecosystem.
