Application Performance Monitoring (APM) Market: Instrumenting MERN E‑Commerce with SigNoz
A developer case study describing how the author instrumented a MERN-stack e-commerce application called Ram Store with SigNoz and OpenTelemetry during the Agents of SigNoz Hackathon 2026. The project used a self-hosted SigNoz instance (Docker) and the OpenTelemetry Node SDK with automatic instrumentation for Express, HTTP, and MongoDB, exporting via OTLP gRPC. The instrumentation enabled distributed traces, runtime metrics, and structured logs (Winston) correlated inside SigNoz. The post covers setup steps, observed telemetry (traces, metrics, logs), challenges (Docker networking, configuration), lessons learned, and planned improvements like custom dashboards and alerting. Project source code and a demo video are linked.
Practical developer walkthrough of instrumenting a MERN app with SigNoz/OpenTelemetry; useful for engineers adopting APM but not industry‑shifting.
Key Takeaways & Evidence Grounding
- Author integrated SigNoz into a MERN e-commerce application named Ram Store as part of the Agents of SigNoz Hackathon 2026.
- SigNoz was self-hosted locally using Docker to provide observability dashboards.
- OpenTelemetry Node SDK with automatic instrumentation was configured for Express, HTTP, and MongoDB, using an OTLP gRPC exporter.
- Winston Logger was integrated to produce structured logs that can be correlated with traces in SigNoz.
- Project assets (GitHub repository and demo video) are published alongside the blog post.
