摘要： A method is provided to diagnose one or more malfunctions in a virtual network having a network functionality implemented in a distributed manner by hypervisors, each performing part of the network functionality. The method includes receiving user input of observed facts about the virtual network, where the observed facts include identifiers of virtual components in the virtual network, and adding the observed facts to a knowledge base. The method further includes, in response to the identifiers of the virtual components, querying agents on the hypervisors for collected facts related to the virtual components, receiving and adding the collected facts to the knowledge base, and applying logic rules to the knowledge base to produce one or more diagnoses of the virtual network.

摘要： A calculation unit calculates, for each of a plurality of systems in which a countermeasure is taken, a maturity index of the system, indicating the degree of operational stability of the system, based on a value related to a non-functional requirement of the system. An evaluation unit evaluates usefulness of the countermeasure for a particular system based on similarity of configuration between the particular system and the system, timing that the countermeasure is taken, effects of the countermeasure, and the calculated maturity index.

摘要： In various embodiments, methods and systems for coordinating, between a host and a tenant, fault recovery of tenant infrastructure in a distributed system is provided. A fault occurrence is determined for a tenant infrastructure in the distributed system. The fault occurrence may be a software failure or hardware failure of the tenant infrastructure supporting a service application of the tenant. A fault recovery plan is communicated to the tenant to notify the tenant of the fault occurrence and actions taken to restore the tenant infrastructure. It is determined whether a fault recovery plan response is received from the tenant; the fault recovery plan response is an acknowledgement from the tenant of the fault recovery plan. Upon receiving the fault recovery plan response or at the expiration of a predefined time limit, the fault recovery plan is executed to restore the tenant infrastructure.

摘要： In a set of problem log entries from a computing system, a subset of the set of problem log entries are identified, which pertain to a failed request. The subset is compared to a reference model which defines log entries per request type under a healthy state of the computing system, to identify a portion of the subset of problem log entries which deviate from corresponding log entries in the reference model. In the portion of the subset, at least one high-value log entry is identified. The at least one high-value log entry is output.

摘要： A management system manages a computer system including multiple monitoring-target devices. A storage device of the management system stores a general rule, general plan information, unresolved information, and configuration information. A control device of the management system creates multiple expanded rules based on the general rule and the configuration information, and if an event related to any of the multiple monitoring-target devices has occurred, identifies, based on the multiple expanded rules, a first conclusion event constituting a candidate for the cause of the occurred event, creates, based on the general plan information, one or more expanded plans, which are recovery plans that can be implemented if the first conclusion event is a cause, identifies an unresolved event based on the unresolved information, identifies a risk site based on the identified unresolved event, and displays data showing the first conclusion event, expanded plan, and risk site.

摘要： A method, system, and computer program product for performing user-initiated logging and auto-correction in hardware/software systems. Embodiments commence upon identifying a set of test points and respective instrumentation components, then determining logging capabilities of the instrumentation components. The nature and extent of the capabilities and configuration of the components aid in generating labels to describe the various logging capabilities. The labels are then used in a user interface so as to obtain user-configurable settings which are also used in determining auto-correction actions. A measurement taken at a testpoint may result in detection of an occurrence of a certain condition, and auto-correction steps can be taken by retrieving a rulebase comprising a set of conditions corresponding to one or more measurements, and corrective actions corresponding to the one or more conditions. Detection of a condition can automatically invoke any number of processes to apply a corrective action and/or emit a recommendation.

摘要： A method for performing data processing through a pipeline of components includes receiving a set of training observations, each including partial user feedback relating to error in data output by the pipeline for respective input data. Some pipeline components commit errors for at least some of the input data, contributing to an error in the respective output data. A prediction model models a probability of a pipeline component committing an error, given input data. Model parameters are learned using the training observations. For a new observation which includes input data and, optionally, partial user feedback indicating that an error has occurred in processing the new input data, without specifying which pipeline component(s) contributed to the observed error in the output data, a prediction is made as to which of the pipeline components contributed to the error in the output (if any).
