A method, system, and program, product for analyzing a computer network comprising one or more domains, each of the one or more domains comprising a plurality of nodes and one or more links, the method comprising calculating the health of the computer network, determining, based on the computer network health, if an infrastructure problem exists, identifying, based on the determination, a domain of the one or more domains of the computer network, further identifying, based on the identified domain, an infrastructure problem selected from the group comprising the plurality of nodes and the one or more links of the identified domain, determining an origin of the cause of the infrastructure problem based on the identified infrastructure problem.

Automated top-down multi-abstraction infrastructure performance analytics-network infrastructure-as-a-service

Methods and apparatus to provide event correlation based on causality equivalence. In one embodiment, a raw notification and a causality notification are generated for a raw event. The causality notification corresponds to a causality equivalence class in a plurality of causality equivalence classes.

Automated top-down multi-abstraction infrastructure performance analytics -network infrastructure-as-a-service perspective

A method, apparatus and computer program product for providing scalability of a resource management and analysis system is disclosed. A method, apparatus and computer program product for providing scalability of a resource management and analysis system is disclosed. The method comprises the steps of receiving and storing information associated with each of the managed elements by a first system, determining a topology of the distributed system from the received managed element information, providing selected information regarding the topology to each of a second and a third system, wherein progressively less specific information is provided to the second and third systems, receiving, at the second system information, regarding status of the managed elements and determining an aggregated status of the managed components and performing, at the third system, an analysis based at least on the aggregated status information and the selected topology information.

Method and apparatus for providing scalability in resource management and analysis system- three way split architecture

A generic analysis model is applicable to a variety of network infrastructure domains, and operable for causal analysis in a common manner independently of the corresponding underlying domain. The generic analysis model may be employed to model root cause analysis and impact analysis for different resource management systems such as enterprise networks, storage area networks, service provider networks and business process management. Such a model improves performance and scalability by simplifying analysis model for a given solution, and decouples the development from topology building and analysis implementation.

Method and apparatus for analyzing network infrastructure

A method, apparatus and computer-program product for performing a system analysis of a system is disclosed. The system is represented as a plurality of independent model domains, wherein the model domain represents selected ones of a plurality of components and the relationships among the components and the method comprises the steps of representing, as proxies, selected ones of the plurality of components of a first domain, wherein the relationships among the components are limited to direct relationships among adjacent ones of the components, wherein the first domain representation is available to a second domain, providing events occurring in the first domain to the second domain, providing a mapping between a plurality events and a plurality of observable events occurring among the proxy components of the first domain and a plurality of observable events occurring among the components of the second domain, wherein the mapping is represented as a value associating each event with each observable event, and performing the system analysis based on the mapping of events and observable events.

Performing model-based root cause analysis using inter-domain mappings

The present invention describes a system and method for managing a complex comprising a reference model store subsystem providing a reference model of the complex, a reference model generation subsystem coupled to the reference model store subsystem, wherein the reference model generation subsystem modifies the reference model to generate a proposed reference model and a change procedure generator subsystem coupled to the reference model store subsystem, wherein the change procedure generator subsystem provides a procedure comprising one or more changes required to transform a complex as represented by a reference model into a complex as represented by the proposed reference model, wherein the change procedure generator subsystem includes a plurality of object templates associated with desired change operations, each of the object templates providing instruction to transform the complex as represented by the reference model into a complex represented by the proposed reference model.

System and method for managing computer networks

A method and apparatus for specifying and generating an alteration in a model representative of a system composed of a plurality of components, the method comprising the steps of associating configuration non-specific representations with corresponding functions operable on the model, each of the configuration non-specific representations includes representations of objects and attributes of, and/or relationships among system components, associating configuration non-specific representations of desired changes to the model for enabling alterations to the objects, attributes, relationships and/or functions of the objects, attributes and relationships subject to constraints imposed by attributes of the system, and applying the configuration non-specific represented changes to the configuration of a baseline model representation of the system to generate a new configuration non-specific model where the changes have been applied.
