OpenTelemetry is broader infrastructure
OTel defines APIs, SDKs, collectors, signals, and semantic conventions. It is not itself an observability backend. AgentSight is a concrete profiling product with a narrower agent-run workflow.
AgentSight can feed an existing OTel environment
Use AgentSight where eBPF and local session parsing add evidence that normal instrumentation misses, then export supported LLM activity into the OTel pipeline rather than replacing it.
