media.ccc.de/v...
Observability is the current buzzword in tech, but, as always, there's a kernel of truth. What is observability, how does apply to modern engineering, and why is this relevant to the networking sector?
Key takeaways & learnings:
* What is observability
* Why are metrics, traces(not network traces), and logs the three golden types of data to monitor?
* How should you define what you monitor? I.e. what is a "service" for you?
* What should I monitor to run these services?
