Abstract: Aspects of recovery of an application from an error. An error notification is received from an agent associated with an application, the error notification being indicative of an error encountered during execution of the application. The error notification is compared with error patterns stored in a database to determine a matching error pattern. Further, a recovery action is ascertained and the recovery action is provided to the agent to recover the application from the error.

Abstract: A functional test execution engine (“FTEE”) may be configured to execute test scripts with respect to a server stack. The FTEE may be communicatively coupled to a test script storage device, which may store the test scripts. The FTEE may select one or more test scripts for execution with respect to the server stack. The one or more test scripts may carry out maintenance or diagnostic functions for the server stack. The FTEE may determine the processing resources of the server stack and, based on those processing resources, select a first set of test scripts from the one or more test scripts to execute. The FTEE may cause the first set of test scripts selected to execute with respect to the server stack in order to generate test script results. The FTEE may store the test script results for subsequent analysis and use during execution of subsequent test scripts.

Abstract: Embodiments relate to monitoring computing hardware in a computing infrastructure facility. Image data and environmental data are received and a current operational status for a computing hardware component is determined from the image data. A hardware operational status tracking model and environment tracking model for the computing hardware component are updated. Embodiments can perform a root cause analysis if the current operational status is a fault status to determine if the fault status was caused by environmental conditions.

Abstract: Systems and methods for limiting performance variation in a storage device are described. Storage devices receive work requests to perform one or more operations from other computing devices, such as a host computing device. Completing the work requests may take a response time. In some embodiments, if the response time of executing the work request exceeds a threshold, the storage device may assign additional computing resources to complete the work request.

Abstract: A new approach to resiliency management is provided in a data center wherein servers are constructed dynamically, on-demand and based on workload requirements and a tenant's resiliency requirements by allocating resources from these pools. In this approach, a set of functionally-equivalent “interchangeable compute units” (ICUs) are composed of resources from resource pools that have been extended to include not only different resource types (CPU, memory, accelerators), but also resources of different specifications (specs) and flavors. As a workload is being processed, the health or status of the resources are monitored. Upon a performance issue or failure event, a resiliency manager can swap out a current ICU and replace it with a functionally-equivalent ICU. Preferably, individual ICUs are hosted on one of: resources of a same type each with different specifications, and resources of a same type and specification and different flavors.

Abstract: An operation method of a memory system includes performing a first read operation on a word line corresponding to a read command, using a read voltage set including a first read voltage; performing a second read operation on the word line using a second read voltage greater than the first read voltage, depending on whether error correction on data read through the first read operation fails; and determining a memory block that includes a memory cell to which the word line is coupled as a closed memory block, depending on whether the word line is determined to be an erased word line as the result of the second read operation.

Abstract: The technology disclosed relates to learning how to efficiently display anomalies in performance data to an operator. In particular, it relates to assembling performance data for a multiplicity of metrics across a multiplicity of resources on a network and training a classifier that implements at least one circumstance-specific detector used to monitor a time series of performance data or to detect patterns in the time series. The training includes producing a time series of anomaly event candidates including corresponding event information used as input to the detectors, generating feature vectors for the anomaly event candidates, selecting a subset of the candidates as anomalous instance data, and using the feature vectors for the anomalous instance data and implicit and/or explicit feedback from users exposed to a visualization of the monitored time series annotated with visual tags for at least some of the anomalous instances data to train the classifier.

Abstract: A computer program file or a sequence of processing steps from an authoring environment of a data processing system is used to generate a graph including nodes representing the processing steps is generated. Unique identifiers (tags) are assigned to the nodes. One or more processing steps are optionally modified while preserving the original identifiers. If an error occurs during execution, error information is saved including the processing step that failed and data records that triggered the failure. The identifier of the failed processing step is attached to the error information. The error information is collected and processed. The collected error information is used to correlate the error to the failed processing step and to data records triggering the error using the identifier of the failed processing step recorded with the error information. The correlated error information indicates cause and location of the error.

Abstract: In order to enable to output a final state of a message while reducing output of a message, a message input/output method includes: receiving a reception message; and outputting, when a reception time of the reception message falls within a first predetermined time from reception of a related message related to the reception message, the reception message when a next of the related message is not received within a second predetermined time exceeding the first predetermined time from the reception time.

Abstract: First information for a first event of a computer system is captured, including first event parameters. A first event key is generated, based on the first event parameters. The first information and first key are both stored as a first event in a storage structure, in which the first event key indexes the first event and the captured first information. When second information is captured for a second event, a second event key is generated based on second event parameters of the captured second event. If the second event key matches the first event key, then the first event stored in the event collection system is dynamically updated to store the second event information as part of the first event, to minimize additional storage space needed in the storage structure for the second event.

Abstract: A containerized application is executed within a container in a virtualized container environment. The containerized application exposes service and diagnostic interfaces that allow a container manager to interact with and control different code paths that provide different services from the containerized application. Using the exposed service and diagnostic interfaces, responsive to a container crash and prior to bringing the containerized application back online within the virtualized container environment after the container crash, functionality of the different code paths that provide the different services from the containerized application is validated.
