This gauge counts how many times one individual stage inside the port-discovery FSM workflow has been retried. An administrator seeing a high retry count on this PortDiscoverFsmStage instance knows UCS Manager kept re-attempting that specific stage rather than moving on, which usually indicates a persistent local problem at that step. For example, a stage whose retry count keeps increasing across polls while stageStatus never reaches success points the operator at exactly which step of the workflow is failing repeatedly.
