  • Patent number: 6868367
    Abstract: An apparatus and method is provided for efficiently determining the source of problems in a complex system based on observable events. By splitting the problem identification process into two separate activities of (1) generating efficient codes for problem identification and (2) decoding the problems at runtime, the efficiency of the problem identification process is significantly increased. Various embodiments of the invention contemplate creating a causality matrix which relates observable symptoms to likely problems in the system, reducing the causality matrix into a minimal codebook by eliminating redundant or unnecessary information, monitoring the observable symptoms, and decoding problems by comparing the observable symptoms against the minimal codebook using various best-fit approaches. The minimal codebook also identifies those observable symptoms for which the greatest benefit will be gained if they were monitored as compared to others.

  • Publication number: 20050021742
    Abstract: A method and apparatus are provided for multi-realm system modeling (MRSM) for dividing systems into components, defining realms containing objects representing system components, optionally defining relationships between the system components, defining associations between realms sufficient to unify objects in the realms when needed, and unifying objects in the realms based on the associations. The realms are defined in a way that enables unified processing for various applications of MRSM.

  • Publication number: 20040249610
    Abstract: A method and apparatus are provided for correlating events in a system. Problems and other events can, e.g., be detected in a system that generates symptoms or observable events. A computer-accessible codebook is provided that includes a mapping between each of a plurality of groups of possible symptoms and one of a plurality of likely exceptional events (e.g., problems) in the system. The system is monitored and one or more known symptoms generated by the system are detected. A mismatch measure is determined between each of the plurality of groups of possible symptoms in the mapping and the one or more known symptoms using a computer, while disregarding symptoms in the groups of possible symptoms not determined to be known. One or more of the plurality of likely problems is selected corresponding to one of the plurality of groups having the smallest mismatch measure.

  • Patent number: 6249755
    Abstract: A computer implemented method is provided for determining the source of a problem in a complex system of managed components based upon symptoms. The problem source identification process is split into different activities. Explicit configuration non-specific representations of types of managed components, their problems, symptoms and the relations along which the problems or symptoms propagate are created that can be manipulated by executable computer code. A data structure is produced for determining the source of a problem by combining one or more of the representations based on information of specific instances of managed components in the system. Computer code is then executed which uses the data structure to determine the source of the problem from one or more symptoms.
