UnverifiedStructured traces are an event stream that records each step of an agent run—inputs, decisions, tool calls, return values, latency, token consumption, and trigger reasons—in a machine-readable schema, can be queried, aggregated, and replayed by programs, and are distinct from ordinary human-readable logs.74% similarUnverifiedOpenTelemetry tracing data is composed of multiple spans, where a span represents the time period of a single operation, and multiple spans form a tree structure through parent-child relationships to constitute a trace.69% similarUnverifiedTracing is a structured, async-aware logging and tracing framework that supports OpenTelemetry integration and has become the de facto standard for observability in Rust.67% similarUnverifiedUsage traces are input/output logs, error messages, and execution paths automatically recorded by the system during operation, and are the core feedback source for mainstream LLM optimization frameworks such as DSPy and TextGrad.66% similarUnverifiedA span is the smallest unit of work in distributed tracing, representing an operation with a start time, end time, and metadata, and multiple spans are combined into a trace through parent-child relationships or links.65% similar
