Observability – the good, the bad and the ugly

It covers general problem of creating monitoring and observability without killing your Ops motivation team with False Positives and unexplained alerts.

Problems on this side, pitfalls, anti-patterns, and how to make it right.

How to manage a monitoring zoo. Spaghettification of dashboards. Why Uber needs 9 billion metrics (¯\_(ツ)_/¯) and why this is antipattern. Metrics as a stream of data. We talk about new Flux language from InfluxDb. A bit of time series analysis and defining of pipelines in Flux for metrics data. Drunkyard walk on your metrics or why to measure a randomness.

Antistatic

What’s wrong with static methods (apart from them not being inline with OOP conventions)? Is dependency injection really that great? Is there life after Spring?

These question have been causing a lot of flame for a long time now. Butts hurt bad, but the community haven’t reached the consensus yet. I will share how my own understanding of these things changed over time and where did I end up eventually.
