This course is an excellent high level introduction to Observability. Highly recommended for anyone starting out on this path.

Sensational training, the approached theme, the visualizations... very cool.

The course was fun and very easy to understand

A good course for anyone who want to get fundamental knowledge of Observability.

Nice and simple way to describe what observability is, isn't, and how you should be looking at implementing it in your org. The Olly knight was witty and has obviously sat in the DevOps/SRE seat before based on his insightful thoughts/experiences.

A fantastic introduction to Observability, what it is, what it's for, and how to initiate an Observability strategy. Very creative, thoughtful and engaging, thank you for a great course!

Good background on Observability, what it is, why you would practice it and the benefits it delivers

The presentation starts with "your system is not observable if you cannot determine its state based on its outputs," and goes on from there. The videos are cute, but more importantly, they highlight why observability helps where monitoring falls down. I learned something!

I really liked that it focusses just on the core concepts, giving a nice overview over the most important aspects, namely the overall architecture of observability platforms, their goals, and some of the core things to watch out for when building one, for example data silos. I would recommend taking this 30 minute course for anybody working on distributed systems who hasn't been exposed to observability as a concept or wants to get some poignant overview on the field. Disclaimer: I am employee of the company Observe, Inc., that created this training. The above is my (as best as possible) honest and unbiased opinion.

Compared to HR training videos, this was funny and engaging. And I also learned a few things.

This course was a fun but informational high level overview of observability. I loved walking through it.

This course is a nice introduction to observability concepts and practices for a wide audience.
