  • Vehicle behavior data storing apparatus
    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.

  • METHOD AND SYSTEM FOR SUPPORTING EVENT ROOT CAUSE ANALYSIS
    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.

  • Computer system management method and management apparatus
    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.

  • System management method in computer system and management system
    Patent number: 8554906
    Abstract: To enable the setting of a suitable threshold for a component of each of apparatuses configuring a system. By using management software, a threshold for monitoring the performance of an apparatus to be monitored is set beforehand. When an acquired performance value exceeds the threshold, the acquired performance value is detected as a performance fault event. Further, the management software has a correlation analysis rule representing a causal relationship between the performance fault events in the managed apparatus. When detecting an event, the management software performs fault cause analysis processing to specify a fault cause apparatus and an apparatus (affected apparatus) affected by the fault from a plurality of received events.
