This is a 64-bit counter of connection setup attempts, across all protocols, that were aborted before reaching the established state, whether the abort was initiated by the firewall, the connection initiator, or the responder. Because this total subsumes both cufwConnGlobalNumPolicyDeclined and cufwConnGlobalNumResDeclined, an admin can use it as a first-pass health check before breaking the aborts down into policy-based versus resource-based causes. For example, a rising value here alongside a flat cufwConnGlobalNumPolicyDeclined would point an admin toward resource exhaustion, not access-list denials, as the reason connections keep failing to establish.
