Method and system for performing root cause analysis

Номер: US20120117573A1

Автор: Takahiro Fujita, Tetsuya Masuishi, Tomohiro Morimura, Yutaka Kudo

Принадлежит: HITACHI LTD

A root cause analysis engine uses event survival times and gradual deletion of events to improve analysis accuracy and reduce the number of required calculations. Certainty factors 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 survival time, and when the time 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 certainty factor of each rule by only performing the re-calculation with respect to affected rules that are related with the deleted event. The calculation cost can be reduced because analysis engine processes events incrementally or decrementally.

Fault detection and recovery as a service

Номер: US20120254652A1

Автор: Atul KATIYAR, Chinna Babu POLINATI

Принадлежит: Microsoft Corp

The monitoring by a monitoring node of a process performed by a monitored node is often devised as a tightly coupled interaction, but such coupling may reduce the re-use of monitoring resources and processes and increase the administrative complexity of the monitoring scenario. Instead, fault detection and recovery may be designed as a non-proprietary service, wherein a set of monitored nodes, together performing a set of processes, may register for monitoring by a set of monitoring nodes. In the event of a failure of a process, or of an entire monitored node, the monitoring nodes may collaborate to initiate a restart of the processes on the same or a substitute monitored node (possibly in the state last reported by the respective processes). Additionally, failure of a monitoring node may be detected, and all monitored nodes assigned to the failed monitoring node may be reassigned to a substitute monitoring node.

Принадлежит: Telcordia Technologies Inc

A method for distributed computations for fault-diagnosis in a system whose fault propagation model has deterministic couplings between faults and symptoms includes creating a ‘relation graph’ in which the nodes correspond to the potential faults, with two nodes connected by a ‘relational link’ if their corresponding faults have an observed symptom in common. Each relational link is assigned a weight equal to the sum, taken over the symptoms represented by the relational link, of the reciprocal of the number of distinct fault-pairs that produce each such symptom. The relation graph is then partitioned into several domains, while minimizing the number of cross-domain relational links, which correspond to cross-domain symptoms. In each domain, all the optimal local solutions to the domain's sub-problem are first determined, and then a combination is selected of the local solutions, one from each domain, that explains the maximum number of cross-domain symptoms, where the optimal solution is supplemented, if necessary, with additional faults to explain any remaining unexplained cross-domain symptoms, determining also a bound on the deviation from optimality of the global solution.

Автор: James T. Koo

Принадлежит: SHEYU GROUP LLC

A relatively small amount of programmable logic may be included in a mostly ASIC device such that the programmable logic can be used as a substitute for a fault-infected ASIC block. This substitution may occur permanently or temporarily. When an ASIC block is temporarily substituted, faulty outputs of the ASIC block are disabled just at the time they would otherwise propagate an error. The operations of the temporarily deactivated ASIC block(s) may be substituted for by appropriately programmed programmable logic. Thus, a fault-infected ASIC block that operates improperly 1% of the time can continue to be gainfully used for the 99% of the time when its operations are fault free. This substitution can be activated in various stages of the ASIC block's life including after: initial design; pilot production; and mass production. This provides for cost saving and faster time-to-market, repair, and maintenance even years after installation and use.

Systems, methods, and other embodiments associated with detecting a node death in a clustered distributed system are described. In one embodiment, a method includes transmitting a ping message to a peer node in the network. If a reply to the ping message is not received from the peer node, a query is sent to table of port identifiers that lists ports in the cluster. In one embodiment, the query includes a port identifier associated with the peer node. The peer node is declared as inactive/dead when the query fails to locate a match in the table for the port identifier. When the query locates a match in the table for the port identifier, another ping message is periodically transmitted to the peer node.

Detecting anomalies in real-time in multiple time series data with automated thresholding

Номер: US20140006325A1

Автор: Alain E. Biem

Принадлежит: International Business Machines Corp

An approach is provided for detecting an anomaly in a processing environment. The approach includes using a processor to obtain a series of values collected within a processing interval of the processor in the processing environment. The processor normalizes this first series of values to obtain a first series of normalized values. A second series of normalized values is generated by applying a predictive filter to the first series of normalized values. A comparison score is generated from the normalized values by comparing the first series of normalized values and the second series of normalized values. The approach then determines whether the comparison score represents an anomaly relative to at least one other comparison score derived from values collected within the processing interval.

Systems and methods are provided for any party in a cloud ecosystem (cloud providers of such resources, the intermediate management software for such resources, and the end user of such resources) to detect and resolve faulty resources synchronously or asynchronously, before said faults adversely affect the users' workloads. The system requests a service or set of one or more resources within a cloud, automatically checking the infrastructure for various faults that would cause it to be non-functional, including pre-defined and user-defined checks, and resolving them before including the infrastructure in the working service cluster of resources. The system presents an API to the user that returns only functional, production-quality resources that are not in a faulty state. An API that tests and resolves bad infrastructure can be registered during the request or a preceding/subsequent API call, removing the need for the end-user to deal with various types of infrastructure faults.

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 checks other computers 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.
