This carries the human-readable name of the associated tunnel that triggered the notification, so the admin recognizes the affected service at a glance during incident triage rather than decoding a bare index. Because associated tunnels frequently represent protected customer services, this name field is often the most actionable piece of the alert. For example, seeing the name ent-customer-protection-grp-fwd in the trap immediately tells the admin which customer's forward path just had an event.
