  • Publication number: 20150248319
    Abstract: In analyzing an elaborate computer system which requires large-scale or numerous event propagation models, a law-of-causality matrix gains size, so that significant amount of storage resources has been used in a management computer. To solve such a problem, the management computer to manage the computer system stores topologies, event propagation models, and causality information including one or more causal relations in the storage resources, determines, when the management computer analyzes or detects an event, whether a causal relation has already been created for the event to be analyzed, and creates the causal relation based on a topology and event propagation models, if not yet.

  • Patent number: 8918228
    Abstract: An engine ECU compares an acceleration value with a reference value, which corresponds to an accelerator operation value inputted in response to a user operation on an accelerator pedal, and stores vehicle behavior data when the acceleration value exceeds the reference value. After determining that the acceleration value is larger than the reference value and storing the vehicle behavior data, the reference value is changed to a larger value. After determining that the acceleration value is smaller than the reference value and, for example, a period in which the acceleration value remains lower than the reference value, reaches a set period, the reference value is changed to a smaller value. Thus, the number of times of storing the vehicle behavior data is equalized among vehicle users.

  • Publication number: 20140237297
    Abstract: A computer analyzes the root cause of an event, which has occurred in any of multiple management-target apparatuses, based on one or more rules in a storage device, that denote an association between one or more condition events corresponding to one or more events capable of occurring in any of the multiple management-target apparatuses and a conclusion event, which is the cause in a case where the one or more condition events have occurred. The computer, based on an event occurrence log including contents and an occurrence date and time of an event, determines a first event group, which is multiple events presumed to occur as a result of the same cause, creates a new rule in which the multiple events of the first event group are the condition events and one event of the first event group is the conclusion event, and stores the created new rule.

  • Patent number: 8671186
    Abstract: The present invention makes it possible to analyze a problem spanning multiple domains. A management apparatus stores an analysis rule. The analysis rule defines a relationship between a causal event, which constitutes a cause of a problem, and multiple relevant events, which denote problems created by the causal event. A first management apparatus acquires a relevant event related to a prescribed node apparatus, which is not under management of the first management apparatus, from a second management apparatus, which manages the prescribed node apparatus. The first management apparatus analyzes a problem by applying the relevant event acquired from the second management apparatus and another relevant event related to a node apparatus under the management of the first management apparatus to the analysis rule.
