To instrument a Node.js app for traces and metrics, bootstrap OpenTelemetry early in your startup sequence using the NodeSDK, configure resource attributes, and set up the OTLP exporter to enable end-to-end observability across your deployments.

OpenTelemetry instrumentation in Node.js microservices is used to establish consistent observability by automatically and manually gathering traces, metrics, and logs, enabling production-grade monitoring across distributed workloads.

Yes, you can use OpenTelemetry to add observability to serverless Node.js workloads by configuring the NodeSDK initialization order and OTLP exporters to capture traces, metrics, and logs in serverless environments.

The best way to configure OTLP exporters and resource attributes in Node.js is during the initial NodeSDK bootstrap phase, ensuring proper initialization order to maintain stable resource identity and propagation.

OpenTelemetry initialization order matters in Node.js applications because the NodeSDK must boot early in the app startup to properly intercept and instrument traces, metrics, and logs before application code executes.

Yes, you need graceful shutdown handling for OpenTelemetry instrumentation in production Node.js to ensure that all buffered traces, metrics, and logs are properly flushed via the OTLP exporter before the application terminates.
