By using monitoring data, feedback data, and pooling of failure data from a plurality of electronic devices, real-time failure prediction and diagnoses of electronic systems operating in a network environment can be achieved. First, the diagnostic system requests data on the state of a machine and / or its components and collections thereof as part of the machine's normal operation. Secondly, real-time processing of the data either at the machine site or elsewhere in the distributed network allows for predicting or diagnosing system failures. Having determined and / or predicted a system failure, a communication to one or more remote observers in the network allows the remote observers to view the diagnostic information and / or required action to repair the failure. Furthermore, interrogation of either the particular electronic system, or a database containing data on similar electronic systems by the diagnostic server allows the diagnostic server to refine original diagnoses based on this population data to achieve a comprehensive failure predication / diagnosing system.

A system and method for providing an accurate root cause failure by linking user incident reports to the root cause failure in a diagnostic database that reflects the system's current configuration. The system is pre-populated with pre-identified symptoms that are associated with assets in the system. The pre-identified symptoms are inactive until actual failures with assets are detected by a monitoring application. After the pre-identified symptoms become active, they are presented to service representatives who also answer calls from users. The activated pre-identified symptoms are used to assist the service representatives to solve problems observed by the users.

A system (830) and method (800) for diagnosing a malfunctioning machine. A fault event is selected (806) together with sequential operating parameter data (808) from a selectively focused time interval about the fault event for evaluation of a machine (810). The selectively focused time interval may include data occurring just before, just after, or spanning the fault event. Characterizing information such as slope, rate of change, and absolute sign of the data may be derived (809) from the operating parameter data over the selectively focused time interval and used in the diagnosis. The fault event and operating parameter data may be compared to existing cases in a case database (834). A set of rules (817) or candidate anomalies (841) may be executed over the operating parameter data to further improve the accuracy of the diagnosis.

A technique for determining a root cause of a condition (e.g., service outage) of at least one subject component in a computing environment comprises the following steps / operations. First, one or more components in the computing environment upon which the at least one subject component depends (e.g., antecedents) are identified. Identification comprises traversing at least a portion of a model representative of an existence of one or more relationships associated with at least a portion of components of the computing environment and which is capable of accounting for a full lifecycle (e.g., including deployment, installation and runtime) associated with at least one component of the computing environment. Then, one or more procedures are performed in accordance with the one or more identified components to determine a condition status associated with each of the one or more identified components. By way of example, the inventive techniques may be applied to a distributed computing environment. The computing environment may also be an autonomic computing environment.

The present invention relates to the generation of trace elements within a data processing apparatus having one or more components whose behaviour is to be traced. A trace module is disclosed which is operable to trace changes in a subset of architectural state of a data processing apparatus with which the trace module is coupled. The trace module comprises a trace generation unit operable to receive input signals from one or more components of the data processing apparatus indicative of a change in the subset of architectural state and to generate from one or more of the input signals a number of trace elements indicative of the change so as to enable a recipient of the trace elements to subsequently reconstruct the subset of architectural state. The trace module also comprises a table maintained by the trace generation unit to identify architectural state derivable from previously generated trace elements, the trace generation unit referencing the table in order to determine which trace elements to generate during the trace generation. By providing a table which identifies architectural state which is derivable from previously generated trace elements, the number of trace elements that need to be generated is significantly reduced. This reduction is achieved because the table provides a record of the architectural state which has already been provided to the recipient. Knowing the architectural state which has already been provided to the recipient enables the trace generation unit to determine whether changes in architectural state can be derived by the recipient. Accordingly, the trace generation unit can refer to the table and only those trace elements relating to changes in architectural state which are not derivable by the recipient need be generated. Hence, if the trace generation unit determines that the recipient is able to derive architectural state then no trace elements relating to those changes need be generated.

In many systems, computer software is a common source of failure or instability. The proliferation of multiple interacting applications from several different software vendors leads to “emergent” problems that are difficult or impossible to predict or prevent. The problems are compounded by the use of networks, which introduce the added complexity of applications on multiple machines interacting in complex scenarios. As a result, many business and home users are hindered from using software-based systems to their fullest potential. More effective use of these systems can be aided by an application which can provide services for monitoring, diagnosing, and solving problems that occur in the operation of the machines at a customer facility. In the system described herein, a database contains entries with executable code that can make use of these services in order to monitor, diagnose, and solve specific problems. Each entry in the database addresses a specific problem. The executable code is designed to isolate and recognize the problem, and then implement a fix or workaround for that problem. The executable code is designed to completely automate the entire process of detection and resolution of the problem. Further, manual intervention may be employed to complete the diagnosis or solution.

A method and data processing system assesses the security vulnerability of a network. A system object model database is created and supports the information data requirements of disparate network vulnerability analysis programs. Only the required data from the system object model database representing the network is imported to the programs, which then analyze the network to produce data results from each program. These data results are stored in a common system model database and within the data fact base. Goal oriented fuzzy logic decision rules are applied to determine the vulnerability posture of the network.

An apparatus and method shares predictive failure information between computer system in a computer network. The shared predictive failure information allows dynamically rerouting a network request to avoid a computer system that may fail according to its predictive failure information. According to a first embodiment, if the requested resource on the network has predictive failure information that indicates the resource may soon fail, a message is returned to the requesting computer with information that includes possible alternative sites from which the information may be obtained. If there is an alternative site, the requesting computer system may access the alternative site, thereby avoiding the computer system that may soon fail. If there is no alternative site, the requesting computer system may return an error message, or may simply access the original resource on the chance that is has not yet failed. According to a second embodiment, a router in the network may indicate one or more alternative paths to a resource if the predictive failure information for the router indicates it may soon fail. The requesting computer system may then access the requested resource via the alternative path. In this manner, predictive failure information can be used in rerouting network traffic between computer systems on a network to minimize the effect of a failing, computer system.

A network management system (10) includes a fault diagnosis system (12) connectable to a communications network (20). The fault diagnosis system includes a fault object factory, a path determination module, and a fault diagnosis engine. The fault object factory is constructed and arranged to receive fault data and create fault objects. The path determination module is constructed to determine, in a communications network, a path related to the fault data. The fault diagnosis engine is constructed to perform, using the determined path, a fault analysis on the fault data to diagnose a fault related to the communications network. The network management may also include a help desk system (18), a topology mapper (14) or an impact analyzer (16).

An apparatus and method shares predictive failure information between computer systems in a computer network. The shared predictive failure information allows a requester of a network resource to determine whether the resource will be available to perform the request based on its predictive failure information. According to a first embodiment, predictive failure information is written by each computer system on the network to a common storage that is accessible by one or more other computer systems on the network. When a computer system on the network needs a resource on another system, the requesting computer system can check the predictive failure status of the system that contains the needed resource by reading the predictive failure information in the common storage. If the predictive failure information indicates that the resource may perform the requested function, the requesting computer system issues the request to the resource. In a second embodiment, one or more network protocols for communicating between computer systems on the network are modified so that messages given in response to resource requests include the predictive failure status of the requested system. Thus, if a requester needs data from another computer system, a message returned from that system in response to the request preferably includes predictive failure status or information indicating whether or not the request can be granted. If the predictive failure status or information indicates that the request can be granted, the requester performs the operation on the requested computer system. In this manner, predictive failure information can be used in granting access to resources between computer systems on a network, which allows accesses to be prevented if the predictive failure information indicates that the resource is likely to fail before completing the request.

Various repair actions may be associated based on a probabilistic model. Additional information may be utilized to modify or improve respective probabilities associated with causes and / or repair actions. This additional information may utilize other automated diagnostic information or may query users for additional information.
