This gauge counts how many times the FSM running against the port-discovery object that runs the neighbor-discovery process for a fabric-interconnect port has retried its current step. An administrator seeing a high fsmTry count on this PortDiscover instance knows UCS Manager is struggling to complete that step and has been repeatedly re-attempting it rather than succeeding on the first pass. For example, a PortDiscover instance whose fsmTry keeps climbing on every poll, without fsmStatus ever reaching completion, points the operator toward a persistent underlying fault rather than a one-off glitch.
