DataDog/dd-trace-go v2.1.0

on GitHub

Summary

Application Performance Monitoring (APM)

Client-Side Stats Computation

Client-Side Stats computation is now enabled by default. This feature allows the Go tracer to compute aggregated span statistics locally before sending them to the Datadog Agent, resulting in reduced network traffic and improved performance.

What this means: Instead of sending all raw span data to the Agent, the tracer now sends pre-computed statistics, reducing bandwidth usage while maintaining full observability.

To disable, if needed: Set the environment variable DD_TRACE_STATS_COMPUTATION_ENABLED=false or use tracer.WithStatsComputation(false) when starting the tracer programmatically.

File-based Configurations

Introduced support for configuring SDK products via a file on the underlying Linux system. #3438 Documentation

Baggage improvements

Fixed a distributed tracing bug in the baggage propagator. Also refactored baggage injection and extraction logic for improved performance and readability. #3439 #3597

Application Security Management (ASM)

contrib envoyproxy/go-control-plane:

• API Security
  • Proxy sampler has been implemented for schema generation
  • Support of Json body analysis of requests and responses (using simdjson-go or fallbacking on json-iterator/go if not available)
• Appsec
  • Support of Envoy observability_mode for async and non-blocking requests analysis
