The ability to measure the internal states of a system by examining its outputs (logs, metrics, and traces).
Observability is the ability to understand the internal state of a system using signals like logs, metrics, and traces. It’s how teams detect outages, diagnose slowdowns, and catch issues that break tracking or conversion journeys - before they become expensive.
For marketing sites, observability protects ROI by catching downtime, slow pages, broken forms, and failed conversions early.
