This object holds the friendly, admin-assigned name for a custom application signature that the network device uses to identify and classify a particular application's traffic. Administrators create these display names when defining their own application-detection rules beyond the vendor's built-in signature set, giving each rule a recognizable label for use in policy configuration and reporting. For example, an admin building a custom rule to detect an internal company application might name it 'InternalCRM-App' via this object.
