  • Publication number: 20150248119
    Abstract: A management system has a topology display screen of a management target system with an area, where icons of system components are typically displayed in the related art, which is embedded and displayed with a graph of a monitor value of the system component. A band having a predetermined width is displayed to show a relation between system display objects indicating the system components. The width of the band is determined by the number of requests which are transmitted or received by the system components. When a time-sequential graph of the monitor value of a system component is displayed, a vertical bar which can be operated by an input/output device is displayed in the graph. When the operation of the vertical bar is detected, an icon indicating integrity of the management target system at a time indicated by the vertical bar is displayed in the vicinity of the vertical bar.

  • Publication number: 20150188752
    Abstract: 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.

  • Patent number: 8671313
    Abstract: 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.

  • Patent number: 8369227
    Abstract: 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.

  • Patent number: 8285836
    Abstract: 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.

  • Patent number: 8271492
    Abstract: 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.

  • Patent number: 8117641
    Abstract: 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.

  • Patent number: 8112378
    Abstract: 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.
