In distributed tracing, a Trace represents one complete end-to-end request flow, a Run usually refers to one complete task lifecycle of Agent execution, and a Span is the smallest unit of work within a Trace; a Run often contains dozens or even hundreds of Spans, forming a tree-shaped causal relationship through parent_id.

UnverifiedTrace capture (traces) is borrowed from observability monitoring practices in distributed systems and is used to reconstruct the complete execution path of each AI request.68% similarUnverifiedA trace represents the complete lifecycle of a request or transaction and consists of several spans; each span records an operation with a start and end time and carries a name, attributes, events, and status; spans form a directed acyclic graph through parent-child relationships.67% similarUnverified多智能体系统的调试难度呈指数级增长，需要专门的追踪系统以Span和Trace的层次结构还原完整执行路径66% similarUnverifiedTracing autonomous agents requires fine-grained stage telemetry: every state transition should emit an OpenTelemetry-compliant span, tracking queue dwell time, token usage and model inference latency, tool execution time and returned status codes, and retry counts and dead-letter queue routing.66% similar
