A Java API for advanced faults management

The paper proposes an alternative for modeling managed resources using Java and telecommunication network management standards. It emphasizes functions related to fault management, namely: diagnostic testing and performance monitoring. Based on Java management extension (JMX/sup TM/), specific extensions are proposed to facilitate diagnostic testing and performance measurements implementation. The new API also called Java fault management extension (JFMX) consists of managed objects that model real resources being tested or monitored and support objects defined for the need of diagnostic testing and performance measurements. The paper discusses four Java implementations of a 3-tier client/server scenario focusing on the "SystemUnderTest" package of the new API to instrument a minimalist managed system scenario. These implementations are respectively built on top of the following Java based communication infrastructures: JMX/JFMX, RMI, CORBA/Java, and Voyager/sup TM/. The paper extends the Voyager implementation with JMX/JFMX and uses their dynamic and advanced features to provide a highly efficient solution. The later implementation also uses the mobile agent paradigm to overcome well-known limitations of the RPC based implementations.
