使用 OpenTelemetry 在 Python 中追踪你的 AI 代理

An AI agent that successfully passed all tests returned nonsensical output when faced with a slightly different user query. Despite logs indicating a '200 OK' status, the issue arose somewhere between the prompt and the final output, leaving the source of the error unclear. This observability gap poses a significant challenge for AI agents in production. Traditional logging reveals what happened, while tracing provides insights into where, how long, and in what order each step was executed. For multi-step agents that utilize tools, chain prompts, and make decisions, tracing can drastically reduce debugging time from hours to minutes. OpenTelemetry is recognized as the industry standard for distributed tracing, with the Python SDK (v1.40.0) set to be released in March 2026.
