Example methods, apparatuses, and user interfaces are presented for generation of Application Business groups and determining system health and integrity based thereon. An Application Business group is a correlated group of Applications forming a business process or business service. Each application typically has one or two central application services referred here as an Application Epicenter. After determining an Epicenter, all correlated and important application services one hop away can become part of the Application. Interfaces allow for expansion or shrinking the Application by selecting a number of hops from the Epicenter. Once these Epicenters are defined, additional graphical user interfaces display health and status data of the Application centered around the Epicenter, including any fault data to diagnose problems in the Application.
