Abstract
DIAMONT (DIAgnosis and MONitoring Tool) is an expert system shell for the software and hardware diagnosis of multiprocessors and computer networks. Its task is to select and start test routines, control them with respect to timeouts, collect the test results and combine them to a global diagnosis image.
The test selection strategy of DIAMONT takes into consideration that tests may be done in parallel on parallel systems and is based on an algorithm for resource management. Building the diagnosis image is done using both heuristic and logic inferences.
First versions of DIAMONT are implemented on Sun OS 4.0, using CMP (Concurrent Modula-Prolog), a Prolog interpreter written in Modula-2 which allows to model DIAMONT as a set of cooperating Prolog processes and to parallelize the expert system.
Currently the system is tested with knowledge base prototypes for diagnosing a network of Sun workstations and for diagnosing the fault tolerant multiprocessor ATTEMPTO.
