A few months ago I started my voyage of discovery with Kubernetes; a very powerful DevOps platform/technology. As I began to dig more into how Kubernetes worked and how to best utilize it I started to see the term “Prometheus” being thrown around frequently on blogs. What is this “Prometheus”? Why all the hype about it?

In this blog post I want to give you a complete beginner guide to what Prometheus is, what it does and how to use it. I will not be digging into “How to install Prometheus” in this blog post. Instead I will be explaining how the platform works, how you can use it, and the benefits it can provide you and your team.

If you are in a rush (and let's face it who isn’t these days), then please scroll to the bottom of this blog and read my “TL;DR; Summary”. It contains everything I cover here in a small digestible format, and will only take a minute to read.
