The AgentForce Observability and Diagnostics Guide details that AgentForce Session Tracing provides the most comprehensive visibility into agent operations. The documentation explains: “Session Tracing captures the entire execution flow for each agent session — including reasoning engine decisions, executed actions, prompts, gateway inputs and outputs, error logs, and final agent responses — to provide an end-to-end view of agent behavior.”

Agentforce Analytics (Option A) focuses on aggregated performance metrics like usage, engagement, and accuracy trends rather than deep operational data.

Utterance Analysis (Option B) evaluates specific interactions or conversation snippets but does not include reasoning engine or system-level traces.

Hence, Option C — AgentForce Session Tracing — is correct as it provides detailed, end-to-end diagnostic insight across all agent executions.
