¥Tracing

跟踪本质上是应用从输入到输出所采取的一系列步骤。跟踪包含称为 runs 的单独步骤。这些回调可以是来自模型、检索器、工具或子链的单独调用。跟踪使你能够观察链和智能代理内部，这对于诊断问题至关重要。

¥A trace is essentially a series of steps that your application takes to go from input to output. Traces contain individual steps called runs. These can be individual calls from a model, retriever, tool, or sub-chains. Tracing gives you observability inside your chains and agents, and is vital in diagnosing issues.
