Monitoring looks at health signals through dashboards and alarms. Observability is the ability to explain why something happened. It uses logs, metrics, and traces to connect events, delays, and errors. When teams instrument well, they can spot bottlenecks, understand failures, and fix them faster. Good observability also helps prevent outages by showing patterns before they become problems. ...

Logging, Monitoring and Observability in Systems Logging, monitoring and observability are the three pillars of reliable software systems. Logging records events as they happen, monitoring watches the health and capacity of services, and observability ties these signals together so you can explain what went wrong and why. Used together, they reduce downtime and speed up recovery for teams of any size. Logging Logging is your first source of truth. Do not log everything; log what matters in a structured format. Use fields that stay consistent across services: timestamp, level, service, trace_id, span_id, request_id, and a clear message.
