Request processing in the Java-oriented OMIS compliant monitoring system

Abstract

Performance problems with Java distributed applications due to their complexity, design problems, and communication mechanism motivate building a uniform Java oriented monitoring environment that provides on-line access to the target distributed application and particular elements. A prototype monitoring system, the J-OCM, compliant with the On-line Monitoring Interface Specification (OMIS) concept, provides the ability to observe and manipulate a whole distributed Java application's execution. The paper presents an approach to dealing with the target Java system in terms of components of the distributed system architecture: interface definition, proxy, object manager, naming service, and communication protocol. To follow these approach we consider the stages of processing the requests issued by monitoring based tools like performance analyzers, debuggers, visualizers. © Springer-Verlag Berlin Heidelberg 2004.
