Report #98362

[research] How should I instrument agent traces so they work across observability backends?

Emit OpenTelemetry spans following the GenAI semantic conventions: gen\_ai.invoke\_agent for the agent run, gen\_ai.chat per LLM call with input/output token attributes, and gen\_ai.execute\_tool per tool call. Propagate W3C trace context so agent spans nest under the parent request. Avoid custom span names if you want vendor-agnostic dashboards.

Journey Context:
Proprietary tracing gives rich UX but locks you in. OTel with gen\_ai.\* conventions lets traces appear in Jaeger, Datadog, Honeycomb, and Azure App Insights with consistent filtering. The current gap is that many SDKs still emit custom span names or fail to propagate context into subprocesses/CLI wrappers; align early with the convention rather than retrofitting later.
