Learning Observability

With observability becoming more understood and common, I felt it would be useful to compile a list of learning material that people new to this area might appreciate. The better we observe and consequently understand our systems, the better we get at predicting and reducing risks.

A huge thanks to Abby Bangser for making her content available.

Honeycomb

The doyenne’s of observability. These folks are the ones that have tirelessly driven and promoted observability before it became a ‘thing’. There’s a mountain of great content on the honeycomb website. Start with https://www.honeycomb.io/resources/white-papers/ but also they have a podcast and videos so it’s worth checking out their whole site. Plus you can signup for free!

Observability by Doing

if you are the type of person who learns by doing then this observability playground by Abby Bangser is perfect for you. A simple webapp but integrated with loads of monitoring and observability type tools to learn the basics.

I’m holding a Friday mentoring group for testers new to observability starting 15th January 2021. You can signup (https://www.testingtimes.com.au/academy/)
