The correct option is evaluationTracing.

evaluationTracing enables diagnostic traces that show how the service hook matching conditions are evaluated for incoming events. This setting records the condition evaluation logic and the matching decisions so you can see why an event did or did not trigger a subscription when you call the Service Hooks diagnostics endpoint in the 6.2 REST API.

deliveryTracing is focused on tracing the delivery process to external subscribers and webhooks and not on the condition evaluation itself. It helps diagnose network and delivery behavior rather than why an event matched a subscription.

deliveryResults records the outcomes of delivery attempts and responses from subscribers. It does not show the internal evaluation of subscription conditions that determines event matching.
