Node.js agent v12.17.0

Notes

Features

• Azure Function utilization (#3017) (80ab93e)
• Support honoring W3C traceparent sampled flag (#3009) (d903413)
  • By default the agent will not honor the traceparent sampled flag.
  • To control how sampling works with traceparent set the following in config:
    • distributed_tracing.sampler.remote_parent_sampled(when the traceparent sampled flag is 01)
      • always_on: the agent will sample spans
      • always_off: the agent will not sample spans
      • default: the agent will rely on existing priority sampling to make its decisions
    • distributed_tracing.sampler.remote_parent_not_sampled(when the traceparent sampled flag is 00)
      • always_on: the agent will sample spans
      • always_off: the agent will not sample spans
      • default: the agent will rely on existing priority sampling to make its decisions

Code refactoring

• Updated otel bridge to centralize mapping rules for a given span attribute to accomondate semantic convention spec updates (#3010) (c20c36b)

Documentation

• Updated compatibility report (#3013) (8fab715)

Tests

• Pinned openai@4.90.0 to work with @langchain/openai (#3019) (eaa3db0)
