Instrument a microservice for distributed tracing by generating spans for requests, database queries, and external calls. This captures end-to-end traces across HTTP, gRPC, and background tasks using W3C Trace Context propagation.

OpenTelemetry semantic conventions are guidelines for naming span attributes like http.method, http.url, and db.system. Adhering to them ensures your tracing, metrics, and logs generate meaningful, standardized telemetry data across services.

Yes, you can capture logs and metrics in serverless functions using OpenTelemetry. It provides a unified instrumentation approach for distributed systems, capturing telemetry and exporting it via the OpenTelemetry Protocol (OTLP) to a collector or backend.

Trace context propagation across HTTP and RPC boundaries works using the W3C Trace Context standard. It ensures trace identifiers are correctly passed between services, enabling end-to-end observability across distributed systems and external calls.

The best way to export telemetry data is using OpenTelemetry Protocol (OTLP) exporters. They transmit structured logs, metrics, and distributed traces directly to an OpenTelemetry collector or compatible backend for aggregation and analysis.

Yes, instrumenting apps requires generating spans for database queries and external calls. Properly configured spans alongside trace context propagation ensure complete end-to-end tracing across microservices and distributed systems.
