Telemetry — OpenTelemetry instrumentation

When to use

The user wants to:

• See per-turn / per-call latency breakdowns
• Attribute token usage across operations
• Push traces to Jaeger, Grafana Tempo, Datadog, Honeycomb, Langfuse, etc.
• Debug a slow agent end-to-end with structured spans rather than print statements

If they just want quick stdout debugging, point them at LoggingMiddleware instead (see ag2-middleware).

Installation

pip install "ag2[openai,tracing]"
