Captured Attributes

ADK automatically enriches traces with the following attributes to help you filter and analyze your agent's behavior:

• gen_ai.agent.name: The name of the agent being executed.
• user.id: The ID of the user interacting with the agent.
• gcp.vertex.agent.invocation_id: The unique ID of the invocation.
• gcp.vertex.agent.event_id: The ID of the specific event.
• gen_ai.conversation.id: The session ID.

Resources

Reasoning:
New telemetry attributes (gen_ai.agent.name, user.id, etc.) have been added to tracing spans. Documenting them helps users understand what data is available for filtering and debugging.
