Observability and Telemetry for Reliable Systems

Observability and Telemetry for Reliable Systems Observability is the practice of understanding how a system behaves in production. Telemetry is the data you collect to answer questions about that behavior. Together they turn fast, complex software into a readable story. The most common data types are logs, metrics, and traces, each with a clear purpose. Reliable systems require visibility across services, storage, and networks. With good observability, a team can detect anomalies early, locate the root cause faster, and reduce downtime. The goal is not just to collect data, but to turn it into actionable insight for engineers and operators. Clear visibility saves time during incidents and supports steady improvements. ...
