[Bug]: OpenAI agent chat traces don't contain input/output messages and other fields #167
Description
Component
General
Description
For agents using openai python package, the chat traces show up when setting the following env vars:
os.environ.setdefault("OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT", "SPAN_AND_EVENT")
os.environ.setdefault("OTEL_SEMCONV_STABILITY_OPT_IN", "gen_ai_latest_experimental")But these chat traces don't contain the following 4 GenAI fields:
gen_ai.input.messages
gen_ai.output.messages
gen_ai.tool.definitions
gen_ai.system_instructions
These fields are vital to debug agents using LLMs.
I've tried my experiments with a version of this sample agent that's the repo: https://github.com/microsoft/opentelemetry-distro-python/blob/9d3b25fa48c8bbd283203aa1757a0aa774458ff7/samples/openai/sample_openai_agents.py
Expected Behavior
Chat traces from openai agents should populate the following 4 GenAI fields:
gen_ai.input.messages
gen_ai.output.messages
gen_ai.tool.definitions
gen_ai.system_instructions
Steps to Reproduce
Use the repo agent with app insights: https://github.com/microsoft/opentelemetry-distro-python/blob/9d3b25fa48c8bbd283203aa1757a0aa774458ff7/samples/openai/sample_openai_agents.py
Environment
Hosted Agent on Foundry
