observability-sentinel

What problem does it solve?

Provides a cohesive approach to instrumenting applications with OpenTelemetry, enforcing structured JSON logs with trace context, and bridging logs, metrics, and traces to support Observability Driven Development (ODD).

Core Features & Use Cases

• Instrument applications using OpenTelemetry SDKs to generate traces, metrics, and logs.
• Design structured logs (JSON) with correlation IDs to link related events across services.
• Connect logs, metrics, and traces (the three pillars) to provide unified visibility.
• Set up Golden Signals (latency, traffic, errors, saturation) to monitor service health and performance.
• Use cases include configuring logging for Node.js (Winston, Pino), Python logging; debugging distributed systems; and responding to requests to add monitoring or trace requests.

Quick Start

Run a sample app that emits OpenTelemetry traces and JSON-structured logs to verify end-to-end observability.
