havainnoitavuutta
Observability, or havainnoitavuutta in Finnish, refers to the ability to understand the internal state of a system based on its external outputs. In computing and software engineering, it's a crucial concept for managing complex, distributed systems. Observability allows engineers to ask questions about their system's behavior that they might not have anticipated during its design. This is achieved by collecting and analyzing various types of telemetry data, commonly known as logs, metrics, and traces.
Logs provide detailed, event-based records of what happened within a system. Metrics are numerical measurements that
Effective observability goes beyond simply monitoring. While monitoring tells you that a system is down or
