Details Panel#
The Details Panel provides in-depth information about traces and their spans, letting you inspect every aspect of your LLM interactions.
Opening the Panel#
Click any trace in the Traces view to open its details in a sidebar panel.
Panel Sections#
Timeline#
At the top of the panel, a timeline visualization shows:
- Trace duration — Total time from first to last span
- Span breakdown — Individual spans with their relative timing
- Parallel operations — Multiple concurrent spans displayed vertically
Click on any span in the timeline to jump to its details below.
Trace Properties#
High-level information about the entire trace:
| Property | Description |
|---|---|
| Trace ID | Unique identifier for this trace |
| Duration | Total elapsed time |
| Spans | Number of spans in the trace |
| Start Time | When the trace began |
| Project | Associated project name |
Span Properties#
Each span represents a single operation. Click a span to see:
| Property | Description |
|---|---|
| Span ID | Unique identifier for this span |
| Parent ID | ID of the parent span (if nested) |
| Operation | Type of operation (e.g., chat/completions) |
| Duration | Time taken for this span |
| Status | Success, error, or pending |
GenAI Properties#
For spans tagged with gen-ai, you'll see LLM-specific data:
Request Details#
| Property | Description |
|---|---|
| Model | Model used (e.g., gpt-4o-mini) |
| Provider | LLM provider (OpenAI, Anthropic, etc.) |
| Temperature | Sampling temperature |
| Max Tokens | Token limit for the response |
Messages#
The full conversation history:
- System — System prompt
- User — User messages
- Assistant — LLM responses
- Tool — Tool calls and results
Token Usage#
| Metric | Description |
|---|---|
| Input Tokens | Tokens in the prompt |
| Output Tokens | Tokens in the response |
| Total Tokens | Combined count |
| Estimated Cost | Based on model pricing |
Copying Data#
Click the icon next to any field to copy it to your clipboard.
Quick copy options:
| Data | How to Copy |
|---|---|
| Trace ID | Click the ID or use the copy button |
| Full Prompt | Use the copy button in Messages section |
| Full Response | Use the copy button next to assistant messages |
| JSON Export | Right-click → Export as JSON |
Multi-Span Traces#
When a trace contains multiple spans (common with agents, chains, or RAG pipelines):
- The timeline shows all spans and their relationships
- Nested spans are indented to show the parent-child hierarchy
- Click between spans to compare timing and content
Understanding Span Hierarchy
Use X-Loop-ParentID headers in your code to create meaningful hierarchies. This helps visualize which LLM calls are part of which workflow steps.
