摘要： 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 (121) checks other computers (102) 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.

摘要： 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.
摘要翻译：根本原因分析引擎使用事件持续时间和逐渐删除事件，以提高分析准确性并减少所需计算的数量。每次收到事件通知时，都会重新计算相关规则的匹配比例。计算结果保存在分析引擎的规则存储器中。每个事件都有有效的持续时间，当持续时间到期时，该事件将从规则存储器中删除。在规则存储器中保存的事件可以被删除，而不会影响规则存储器中保存的其他事件。然后，分析引擎可以通过仅针对与已删除事件相关的受影响规则执行重新计算来重新计算每个规则的匹配比例。计算成本可以减少，因为分析引擎会逐渐或者递减地处理事件。分析引擎可以确定最可能的结论，即使一个或多个条件元素不是真的。

摘要： 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.
