| A robustly engineered end-to-end enterprise monitoring (E2E-EM) capability is the key to success for complex enterprise systems as they transform to provide the highest level of service assurance under Network Operations (NetOps) supporting global net-centric solutions across a service-oriented architecture. This paper presents an E2E-EM framework established as part of an effort sponsored by the Defense Information Systems Agency to develop a set of E2E-EM guidelines, the goals of which are governed by transformational tenets. To a provider of global net-centric solutions supporting a wide spectrum of operational scenarios, it is a significant challenge to operate in an environment that is extremely diverse and complicated. Hence, it is necessary to adopt a disciplined approach to developing an effective framework towards implementation of the guidelines. The framework discussed in this paper addresses the guidelines goals through a service-based approach in which monitoring tasks are initially separated into four domains (transport, network, application, and security). Within each domain, the framework also identifies component layers on which an end-to-end capability relies in order to provide the desired end-user services. However, a domain-based monitoring methodology is insufficient for identifying and tracking messages that use multiple services across multiple domains. To provide sufficient end-to-end monitoring coverage, a reference monitoring architecture is introduced that defines a second dimension, called monitoring planes (usage, control, security, and management). Each plane encompasses all monitoring domains, thereby enabling the enterprise-wide monitoring, event correlation, and data sharing required for an end-to-end enterprise solution. This architecture also provides a set of “common terminology” for addressing E2E-EM needs and creates a reusable design in which multi-domain, multi-plane, and multi-vendor components can contribute. |
