  • Publication number: 20160099845
    Abstract: A user interface includes a graphical topological representation of an information system. Information is collected regarding connections between switches, storage nodes and computer nodes in the information system. Any sub networks in the system are identified based on the collected information and classified as LANs or SANs. Connections between the various components are determined, and a layout of any identified LANs, computer nodes, SANs, and storage nodes is established for generating the topological representation in the user interface. The graphical topological representation of the information system is displayed in the user interface with the LAN icons, computer node icons, SAN icons and storage node icons laid out in a matrix-like arrangement of columns and rows, such that for LANs, computer nodes, SANs and/or storage nodes that are connected to each other, the corresponding icons are located on or near a same row in the graphical topological representation.

  • 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: 9003230
    Abstract: A technique determines which configuration change(s) caused an application invocation failure of a computer application without the need for a knowledge database. To determine which configuration change is the most likely cause, the cause analysis program checks other computers that have experienced the same configuration changes. The cause analysis program checks and counts the application invocation results before and after each configuration change is done. If the same configuration changes are found in the other computers, the program checks whether each configuration change caused or cured the same problem in that computer. The program counts the similar cases for all of the computers. Subsequently, the program calculates the ratio of those instances involving a change from success to failure and the ratio of those instances involving a change from failure to success out of all instances for each configuration change.
