"This is observability—essentially the gathering, visualization, and analysis of metrics, traces, and logs in one place in order to gain full insight into a system’s operation." 🚫🚫🚫

No. That is not observability, that is TELEMETRY. Quit doing this.

Observability is how well you can understand the inner workings of your system simply by observing its outputs. Look it up.

This MATTERS, because observability is how you debug and understand unknown-unknown states, ones you've never seen before and could not have predicted.

Understanding the long tail of crazy unknown states a system can get itself into is _the_ problem of operating distributed systems.

If you have to ship new custom code to handle a state, it is not observability. If you aggregate at write time, it does not provide observability.

Vendors, please stop fucking this up just so you can say your $(whatever you sell) is $(buzzword). We need technical terms to have meaning.
