A new frontier faces operations teams making the transition from focusing on device availability to focusing on service quality and performance. Making this change requires expanding the scope of management activities and rethinking management tools architectures to embrace sustained performance monitoring spanning all of the contributing technologies and domains that must come together to comprise today's highly flexible and dynamic services. Tooling options for integrated, service-centric performance management include single-vendor suites, domain-specific best of breed products, and a promising alternative - cross-domain, integrated performance managers. This latter class can offer a compelling balance of functional capability matched with low integration costs and low total cost of ownership. This ENTERPRISE MANAGEMENT ASSOCIATES® (EMATM) paper evaluates priorities for service-centric performance management and analyzes how one cross-domain integrated solution, Watch4net's APG, measures up.
