href="../conceptual_guides/intro_agents">设计上的不可预测性</a>（如果可预测，直接使用传统代码即可）。</p> <p data-svelte-h="svelte-gqd4q8">检查运行记录同样困难：多步骤的Agent往往会快速在控制台生成大量日志，而大多数错误只是”LLM 低级错误”类型的问题，通常LLM会在后续步骤中通过生成更好的代码或工具调用来自我修正。</p> <p data-svelte-h="svelte-1a0aea2">因此，在生产环境中使用监控工具记录Agent运行过程，对于后续检查和分析至关重要！</p> <p data-svelte-h="svelte-1tp9jpg">我们采用 <a href="https://opentelemetry.io/" rel="nofollow">OpenTelemetry</a> 标准来实现Agent运行监控。</p> <p data-svelte-h="svelte-88ya86">这意味着您只需添加少量监控代码，即可在正常运行Agent时自动记录所有信息到监控平台。以下是在不同OpenTelemetry后端实现此功能的示例：</p> <p
