Publication number: 20150188752Abstract: A root cause analysis engine uses event survival times and gradual deletion of events to improve analysis accuracy and reduce the number of required calculations. Certainty factors of relevant rules are recalculated every time notification of an event is received. The calculation results are held in a rule memory in the analysis engine. Each event has a survival time, and when the time has expired, that event is deleted from the rule memory. Events held in the rule memory can be deleted without affecting other events held in the rule memory. The analysis engine can then re-calculate the certainty factor of each rule by only performing the re-calculation with respect to affected rules that are related with the deleted event. The calculation cost can be reduced because analysis engine processes events incrementally or decrementally.Type: ApplicationFiled: March 11, 2015Publication date: July 2, 2015Inventors: Yutaka KUDO, Tetsuya MASUISHI, Takahiro FUJITA, Tomohiro MORIMURA

Patent number: 8671313Abstract: A management apparatus and a management method that enable parsing processing to be executed efficiently by means of a working memory of a fixed size are proposed. One or more predefined rules are divided into one or more rule segments that comprise a condition and a conclusion that each form part of the rule, and the rule segments obtained through the division are stored in the secondary storage, and when an event notification from the information processing device is received, one or more related rule segments are selected and, by linking the selected one or more rule segments in the memory as required, a rule parsing network is constructed that indicates relationships between rules in the memory, an inference is derived on the basis of the constructed rule parsing network, and rule segments that are not readily used in inference derivation are deleted from the memory.Type: GrantFiled: June 24, 2013Date of Patent: March 11, 2014Assignee: Hitachi, Ltd.Inventors: Tomohiro Morimura, Masashi Kunii, Yutaka Kudo

Patent number: 8369227Abstract: Provided is a management system for managing a plurality of management target information processing apparatuses including a plurality of network apparatuses and a computer. This management system determines the reachability of a route network apparatus as a network apparatus on a communication between the system and the computer, and calculates a certainty factor concerning the certainty on whether a prescribed network apparatus contained in a route network apparatus based on the reachability is the cause of unreachability from the management system to the computer. The management system subsequently displays information showing that communication from the management system to the computer is unreachable, and the certainty factor as the certainty that the prescribed route network apparatus is the cause of unreachability.Type: GrantFiled: March 24, 2009Date of Patent: February 5, 2013Assignee: Hitachi, Ltd.Inventors: Tomohiro Morimura, Kiminori Sugauchi, Takaki Kuroda

Patent number: 8285836Abstract: A policy creation support system is provided, which is capable of reducing cost for creation of an effective autonomic control policy. The policy creation support system measures information indicating performance of a monitoring target system, with regard to a monitoring item of a designated type, for each resource amount of an expandable resource, and selects one representative measurement value from among measurement values on a resource-amount basis. Then, the policy creation support system outputs the monitoring item, the resource amount serving as the monitoring item, and a range of the measurement value corresponding to the resource amount, as a countermeasure decision condition within a policy, by setting a range including the selected representative measurement value as the range of the measurement value.Type: GrantFiled: November 30, 2007Date of Patent: October 9, 2012Assignee: Hitachi, Ltd.Inventors: Futoshi Haga, Tomohiro Morimura

Patent number: 8271492Abstract: To reduce the burden of processing for completing event cause information, which is carried out when a management target node apparatus is added, removed or changed. A management computer determines whether or not partial change to add, delete or change part of information related to an event related to an added, removed or changed node apparatus can be performed or not on the event cause information. The management computer adds, deletes or changes the part of information with respect to the event cause information, when the result of the determination is affirmative.Type: GrantFiled: April 23, 2009Date of Patent: September 18, 2012Assignee: Hitachi, Ltd.Inventors: Takayuki Nagai, Tomohiro Morimura

Patent number: 8117641Abstract: A technique of performing concurrency control of policies is provided, which makes it possible to efficiently utilize resources of an overall information system. According to the present invention, a policy execution device creates a list of components of a application system which are influenced by execution of an action of a policy instance, for respective policy instances. If trigger conditions of another policy instance are newly met during execution of a policy instance, the policy execution device compares a list of components of the policy instance presently being executed with a list of components of the policy instance whose trigger conditions are newly met. If there are no common components in the lists, the policy execution device executes the policy instance whose trigger conditions are newly met, and if there are common components in the lists, the policy execution device suspends the policy instance whose trigger conditions are newly met.Type: GrantFiled: September 27, 2006Date of Patent: February 14, 2012Assignee: Hitachi, Ltd.Inventors: Tomohiro Morimura, Yoshimasa Masuoka, Naoki Utsunomiya

Patent number: 8112378Abstract: A root cause analysis engine uses event durations and gradual deletion of events to improve analysis accuracy and reduce the number of required calculations. Matching ratios of relevant rules are recalculated every time notification of an event is received. The calculation results are held in a rule memory in the analysis engine. Each event has a valid duration, and when the duration has expired, that event is deleted from the rule memory. Events held in the rule memory can be deleted without affecting other events held in the rule memory. The analysis engine can then re-calculate the matching ratio of each rule by only performing the re-calculation with respect to affected rules related to the deleted event. The calculation cost can be reduced because analysis engine processes events incrementally or decrementally. Analysis engine can determine the most possible conclusion even if one or more condition elements were not true.Type: GrantFiled: June 17, 2008Date of Patent: February 7, 2012Assignee: Hitachi, Ltd.Inventors: Yutaka Kudo, Tetsuya Masuishi, Takahiro Fujita, Tomohiro Morimura

Patent number: 8099379Abstract: A performance evaluating apparatus for a rule is provided, which is capable of evaluating a business value of a rule applied to the operation and management of an information system through autonomous control. The performance evaluating apparatus for a rule collects, respectively before activation processing that is prescribed by a rule and after completion of the execution of the processing, a rule execution history and a system state information indicating a state of a monitored information system that is necessary for calculation of the business value. The business value is calculated from the collected system state information and rule execution history by a given calculation formula.Type: GrantFiled: May 6, 2011Date of Patent: January 17, 2012Assignee: Hitachi, Ltd.Inventors: Tomohiro Morimura, Yoshimasa Masuoka
