How are things with observability, what can you tell?

Observability is the ability of a system to provide information about its internal state through metrics, logs, and traces. In Go projects, I used tools like Prometheus for metrics collection, OpenTelemetry for traces, and structured logs with zap or logrus. This allowed for quick identification of bottlenecks and errors in production. An important aspect was building dashboards and alerting to respond promptly to incidents and improve service quality.
