I had used ELK before, but had never actually built the platform myself. I wanted to install it and see whether anything unusual came up along the way. Elastic provides detailed guides, though, so following them made the installation straightforward. Tuning ELK in operation seems harder... but let's start by setting it up! The guides are so thorough that I am only including the links here.
