# Observability

## Technische Erklärung

Observable systems emit correlated signals such as traces, metrics, logs, events, and profiles. Instrumentation, context propagation, service metadata, and queryable telemetry allow teams to investigate known and novel failures and ask why behaviour occurred.

## Geschäftliche Relevanz

Observability shortens incident diagnosis, supports reliability and capacity decisions, and makes distributed systems and automation accountable in production.

## Implementierungsbeispiel

A team correlates a slow customer request across a trace, service metrics, deployment metadata, and logs to identify a database query introduced by a recent release.

## Einschränkungen und häufige Missverständnisse

Collecting large volumes of telemetry does not guarantee insight. Poor instrumentation, missing context, uncontrolled cardinality, retention costs, and alert noise can undermine observability.
