Observability and Monitoring for Resilient Systems Observability helps you answer questions about how a system behaves when users interact with it. It goes beyond simple dashboards by explaining why something happened, not just that it did. Monitoring is the ongoing practice of checking health and performance, with alerts when indicators cross limits.
