Patent Issued for Supporting Detection of Failure Event

July 8, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Gotoh, Yasuhisa (Yokohama, JP); Kaneyasu, Yuhsuke (Tokyo, JP), filed on March 12, 2013, was published online on June 24, 2014.

The patent's assignee for patent number 8762777 is International Business Machines Corporation (Armonk, NY).

News editors obtained the following quote from the background information supplied by the inventors: "The present invention relates to mechanisms for supporting detection of a failure event to maintain a high degree of failure detection accuracy without unduly increasing the amount of symptom storage.

"With the rapid development of computer technology today, computer systems are naturally incorporated in backbone systems constructing a social infrastructure. In order to operate the social infrastructure normally at all times, considerable operation costs are required. An autonomic computing system has attracted attention as a technique for reducing the operation costs as much as possible and increasing the degree of system stability.

"The autonomic computing system is a generic term describing all major areas of technology for constructing a system-scale, self-managing environment, which means an entire system for detecting a problem or failure that arises in a system and autonomously eliminating the problem or failure. Various methods for detecting a problem or failure that arises in a system are disclosed.

"For example, a method exists for root cause identification in which part of a dependency model related to a subject structural element and other structural elements upon which the subject structural element depends is scanned to identify a root cause of a condition of the subject structural element including a failure in order to determine a condition status associated with each of the structural elements. Further, a dependency management method exists for managing dependency information among various components of a computing environment, especially for managing runtime dependencies.

"However, though the method for root cause identification can detect a root cause with a high degree of accuracy by scanning the dependency model everywhere from the upstream to the downstream, if the dependency model is complicated, scanning itself requires significant time, and since the order of scanning the dependency model is not specified, there is a problem that may cause reduction of performance and usability.

"Further, the dependency model is often constructed in the form of a logical formula with event parameters. For example, though the dependency information among components is managed, the dependency information does not include system configuration information. Therefore, even if dependency models to be scanned are narrowed down from the logical formula, there is a possibility of detecting a wrong root cause, and hence there is a problem of making it difficult to improve detection accuracy."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "In one illustrative embodiment, there is provided an apparatus for supporting detection of a failure event, the apparatus comprising a processor and a memory coupled to the processor. The memory comprises instructions which, when executed by the processor, cause the processor to collect history information of a system including plural components, the history information including log information of the system and failure information output from at least one component upon occurrence of a failure in the system. The instructions further cause the processor to generate a detection rule for detecting an event included in a component related to the failure that has occurred. The instructions further cause the processor to store a symptom with additional information added to the generated detection rule. The instructions further cause the processor to acquire system configuration information as configuration information of the system. The instructions further cause the processor to accept selection of an event and extract, from the acquired system configuration information, partial configuration information as system configuration information related to a component that sent out the event the selection of which has been accepted. The instructions further cause the processor to add the extracted partial configuration information to the symptom to update the symptom.

"In another illustrative embodiment, there is a provided a method of supporting detection of a failure event, the method comprising collecting history information of a system including plural components, the history information including log information of the system and failure information output from at least one component upon occurrence of a failure in the system. The method further comprises generating a detection rule for detecting an event included in a component related to the failure that has occurred; storing a symptom with additional information added to the generated detection rule; and acquiring system configuration information as configuration information of the system. The method further comprises accepting selection of an event and extracting, from the acquired system configuration information, partial configuration information as system configuration information related to the component that sent out the event the selection of which has been accepted. The method further comprises adding the extracted partial configuration information to the symptom to update the symptom.

"In accordance with another illustrative embodiment, there is a provided a computer program product comprising a computer recording medium having a computer program recorded thereon capable of being executed on a computer to support detection of an event that has caused a failure in a system including plural components. The program causes the computer to collect history information of the system including log information of the system and failure information output from at least one component upon occurrence of the failure in the system. The computer program farther causes the computer to generate a detection rule for detecting the event included in a component related to the failure that has occurred, store a symptom with additional information added to the generated detection rule, and system configuration information as configuration information of the system. The computer program further causes the computer to accept selection of an event and extract, from the acquired system configuration information, partial configuration information as system configuration information related to a component that sent out the event the selection of which has been accepted. The computer program farther causes the computer to add the extracted partial configuration information to the symptom to update the symptom."
