TasksJavaScript Microservices Instrumentation
Add OTEL tracing and logging to Node.js/JavaScript microservices. Use OTEL SDK v1.39.0, export to OTLP, log lifecycle and HTTP events.
What makes it easy
- JavaScript OTEL SDK is well-documented - npm ecosystem is familiar to models - Auto-instrumentation available
Common failure modes
- Version mismatches - Missing lifecycle logging - Async context propagation issues
