Patent ID: 7676695

Claim:
A system for analyzing computer operations problems, comprising: a fault history database storing a set of fault records, each fault record corresponding to one of a set of possible computer operations problems, having a fault source, and comprising attributes relating to at least one of an identity, category and timing of said one problem; and a fault analysis subsystem operatively coupled to the fault history database and receiving therefrom a subset of fault records, the fault analysis subsystem configured to: determine a set of fault statistics based on the subset of fault records, generate rankings for fault sources responsive to the determined set of fault statistics, and flags for fault sources responsive to a standard deviation of the ranking with respect to a mean of rankings of other fault sources exceeding a given threshold, the fault analysis subsystem configured to cause fault sources having flags to be visually displayed in a manner distinguishable from fault sources not having flags, and responsive to the determination of the set of fault statistics, identify certain fault sources of the set of fault records as being responsible for the computer operations problems.
