fix(serverless): add `base_service` tag for serverless [backport #17238 to 4.7] by zarirhamza · Pull Request #17441 · DataDog/dd-trace-py

zarirhamza · 2026-04-09T21:11:28Z

Backport of #17238 to 4.7.

(cherry picked from commit 93778cc)

Description

Fixes _dd.base_service handling for AWS Lambda environments in the Python tracer, enabling service remapping rules to work on Lambda spans and ensuring trace stats contain a meaningful base_service.

Changes

ddtrace/internal/settings/_config.py — When DD_SERVICE is not configured and the tracer is running in AWS Lambda, config.service is now automatically set from AWS_LAMBDA_FUNCTION_NAME. This mirrors existing GCP (K_SERVICE) and Azure (WEBSITE_SITE_NAME) auto-detection behavior.

ddtrace/internal/schema/processor.py — Removes the Lambda-specific early exit from BaseServiceProcessor. Previously, the processor skipped all Lambda spans to avoid unhelpful base_service values from the runtime. Now that the service is correctly resolved from the function name, the processor runs normally and _dd.base_service is properly attached to spans.

Testing

Existing serverless system tests pass (ALB, API Gateway HTTP/REST, Function URL). Includes new unit tests for Lambda service name auto-detection and base_service processor behavior.

Risks

Low. The change only affects Lambda environments where DD_SERVICE is not explicitly set. The resolved service name (AWS_LAMBDA_FUNCTION_NAME) matches what the extension already uses for extension-based languages, ensuring consistency across runtimes.
