Trace Visualizer

Software componentObservability & EvaluationObservability & Evaluationarc:TraceVisualizer

An analysis interface that renders stored traces as interactive timelines with hierarchical drill-down, error highlighting, side-by-side trace comparison, and span filtering and search.

Responsibility. Renders stored traces for interactive, drill-down debugging.

Also known as: Trace timeline view, Trace explorer, Profiler timeline GUI, Waterfall trace view, Trace reconstruction, Agent collaboration timeline view, Visual reasoning flowchart

Design guidance

SHOULD display multi-agent workflows as one integrated timeline correlated by shared trace IDs, including message passing, handoffs and parallel executions.
SHOULD support filtering spans by tool, latency threshold and error status.

Quantitative guidance

As stated by the sources; verify before use.

Timeline example: retrieval 8.7 s of a 12 s response (72%) versus LLM inference 1.8 s, processing 0.6 s, formatting 0.9 s (Ch3.6).
