Abstract: The disclosed embodiments relate to a system that gathers telemetry data while testing a computer system. During operation, the system obtains a test script that generates a load profile to exercise the computer system, wherein a running time of the test script is designed to be relatively prime in comparison to a sampling interval for telemetry data in the computer system. Next, the system gathers telemetry data during multiple successive executions of the test script on the computer system. The system merges the telemetry data gathered during the multiple successive executions of the test script, wherein the relatively prime relationship between the running time of the test script and the sampling interval for the telemetry data causes a sampling point for the telemetry data to precess through different points in the test script during the multiple successive executions of the test script, thereby densifying sampled telemetry data points gathered for the test script.

Abstract: One or more techniques and/or computing devices are provided for implementing synchronous replication. For example, a synchronous replication relationship may be established between a first storage controller hosting local storage and a second storage controller hosting remote storage (e.g., replication may be specified at a file, logical unit number (LUN), or any other level of granularity). Data operations and offloaded operations may be implemented in parallel upon the local storage and the remote storage. Error handling operations may be implemented upon the local storage and implement in parallel as a best effort on the remote storage, and a reconciliation may be performed to identify any data divergence from the best effort parallel implementation. Storage area network (SAN) operations may be implemented upon the local storage, and upon local completion may be remotely implemented upon the remote storage.

Abstract: Methods and systems for performing mainframe batch testing and/or property-based validation testing using a finite-state machine are provided. According to certain aspects, a validation server may receive a set of batch data designed to validate a property under test, such as during mainframe batch testing. A validation server may validate that the set of batch data is in a proper format. The validation server may then cause a finite-state machine to process instructions contained within the set of batch data. Once the finite-state machine processes the set of batch data, the validation server may then validate that the finite-state machine adheres to the property under test. If the validation fails, the validation server may generate an error report describing the failure.

Abstract: Environmental data, associated with a first computer, is received. Social media data, associated with the first computer, is also received. A first severity value, based on the environmental data, is determined. A second severity value, based on the social media data, is determined. A first weighted severity score is determined. The first weighted severity score is a combination of the first and second severity values. One or more actions is determined. The determined action is one of a recovery point objective action or a recovery time objective action. Each action has a threshold. Whether the first weighted severity score is equal to or greater than any threshold associated with any action is determined. In response to determining that the first weighted severity score is equal to or greater than one or more thresholds, each action associated with each threshold is implemented.

Abstract: A framework for improving robustness in the execution of software workflows is described herein. One such workflow is a testing scenario, where multiple testing modules are to be executed sequentially, with some of the modules receiving as input the output of other modules. Many types of modules are contemplated, such as Application Program Interface (API) modules, User Interface (UI) modules, Database (DB) modules, and the like. Each of these modules may invoke, respond to, and/or extract data from various subjects of the testing scenario, among other operations. One aspect of the invention wraps each of these modules in a software component, such that disparate module types can be operated on with a common interface. In one embodiment, the common interface enables a test executor to retry and/or debug the software components in novel ways.

Abstract: Quorum based anomaly detection utilizes multiple entities to detect and attempt to configure a repair task for an anomaly. Once the repair task is generated, a system is used to assign the task to a worker entity while recording the responsibility of that task with the worker in a persistent storage. If the worker entity crashes, the degraded worker status will eventually be detected, and all tasks associated with that worker will be re-assigned. Once a worker finishes a task, the assignment information for the task is transitioned to a completed state.

Abstract: A low latency digital clock fault detector has an edge detector including a delay line generating pulses on edges o an incoming clock signal of a width determined by the length of said delay line. A watchdog timer with flip-flops in a pipeline configuration has a first input held at a static logic level, a second input receiving a reference clock, and a third reset input. The watchdog is being responsive to the pulses to maintain a stable output in the presence of said pulses and generate a fault indication in the absence of the pulses.

Abstract: 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.
