Abstract: A computer system comprises a system management subsystem and one or more operational subsystems, which are connected in a network, and the operational computer subsystem comprises notifying means for notifying management information relating to all resources under the management of a host computer to the system management subsystem, and verifying means for verifying the resources under the management in accordance with an instruction of the system management subsystem, notifying the results to the system management subsystem, and the system management subsystem comprises state display means for displaying a total system state in a standardized format common to the whole system, and instructing means for instructing the verifying means to verify.

Abstract: According to the present invention, an on-line monitoring system which detects faults of one or more applications of the computer system comprises monitoring means for instructing each on-line control means included in the applications to execute routine processing for application programs periodically, and in a case that the time required for the routine processing is longer than a predetermined time, the monitoring system decides that a fault which deteriorates application functions or a fall in processing efficiency occurs.

Abstract: The present invention is for a fault detecting system for a computer network comprising a plurality of computer systems which are placed apart and interconnected by a communication network, and a central computer system monitors faults in the network. The central computer system stores fault information which is transmitted from a plurality of computer systems and judges whether the information indicates a fault occurring for a slight fault or for a serious fault based on the length of the duration of the fault, and display means performs the alarm display for a case of a serious fault and does not display for a case of a slight fault. As a result, the central computer system effectively detects faults in a computer network in which a plurality of computer systems are interconnected with the central computer system by means of a monitoring system that automatically distinguishes serious faults from slight faults.
