Research Report on an Overview of a Proposed Monitoring Facility for the Large-Scale, Network-Based OCLC On-Line System.
Dominick, Wayne D.; And Others
This report addresses the critical importance of measuring and evaluating information systems functioning within computer network environments. The focus is on the significant benefits associated with using automated monitoring as the primary information system measurement mechanism within such computing architectures. The large scale, network-based, state-of-the-art OCLC online system is utilized as the information system environment in support of these research and development activities. Within this environment an overall structure for a generalized, automated monitor design is proposed. Monitoring specifications are illustrated at the network supervisor level, the applications processor level, and the database processor level within the OCLC system network architecture. The monitoring concepts, techniques, and parameters presented within this report represent a strong foundation for information system measurement, analysis, and evaluation. When combined with complementary measurement facilities such as controlled benchmarks and synthetic programs, simulation models and controlled user interface experiments, a total comprehensive methodology for information system evaluation can be realized. The principles of automated monitoring have proven their extensibility and generalizability across numerous types of information systems. It is concluded that automated monitoring should be viewed as an essential self-measurement capability within all future information system designs. (Author/RAA)
