| Pattern | Advantages | Disadvantages |
| ---------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
-| **Span Events** | - Leverages existing trace configuration and tooling - Minimal overhead, no additional spans created - Maintains trace context relationships - Simpler than creating spans | - Requires an active span to function - Must gracefully handle absence of active span - Limited to span lifetime and context. |
-| **Event Logging** | - Works independently without active spans - Aligns with OpenTelemetry's emerging direction - Suitable for environments without tracing - Simpler implementation model | - Requires an event exporter to be configured - Processed and stored separately from spans - Event logging standards still evolving |
-| **Standalone Spans** | - Distributed traces contain every evaluation - Detailed timing information - Full span lifecycle control | - Creates one span per evaluation - May clutter trace visualizations - Increased overhead and resource usage - Potential performance impact at scale - More complex implementation |
