End-to-End Observability Project - Zero-to-Hero

Observability is the ability to measure a system’s current state based on the data it generates, recorded as logs, metrics, and traces. Logs, metrics, and traces are known as the “three pillars of observability.”

  • Logs: Logs record the details of an event.

  • Metrics: Metrics capture the numeric measurements used to quantify the performance and health of services.

  • Traces: Traces track how services connect from end to end in response to requests.

Implement observability using a combination of instrumentation methods, including open-source instrumentation tools, such as OpenTelemetry.

  • Observability: The ability of a system to provide deep insights into its internal state, often focusing on unknown issues.

  • Monitoring: Actively tracking predefined metrics and thresholds to ensure system health.

  • Telemetry: The process of collecting and transmitting data from remote (or) inaccessible sources.

Observability helps cross-functional teams understand and answer specific questions about what’s happening in highly distributed systems.
