Class CompositeTracer
- Namespace
- LMKit.Agents.Observability
- Assembly
- LM-Kit.NET.dll
A tracer that forwards to multiple underlying tracers.
Use this to send traces to multiple destinations simultaneously (e.g., console for debugging and OpenTelemetry for production monitoring).

Examples
Forwarding to console + in-memory tracers at once:
using LMKit.Agents.Observability;
var memory = new InMemoryTracer();
IAgentTracer tracer = new CompositeTracer(new ConsoleTracer(), memory);
using var executor = new TracingAgentExecutor(new AgentExecutor(), tracer);
await executor.ExecuteAsync(agent, "Run the daily check.");
// Inspect spans collected by the in-memory tracer (console got the same data live).
var summary = memory.GetTraceSummary();
Remarks
Note: Span operations are forwarded to all tracers, but only the first tracer's span is returned. This means attributes set directly on returned spans only affect the first tracer. For full multi-tracer support, use the tracer's Log and RecordMetric methods.
