Abstract: A method, system, and product for monitoring the availability of a data processing system are proposed. The system runs a management application involving the periodic transmission of blocks of data from multiple local computers to a central computer. Whenever a block of data must be transmitted by a generic local computer, an expected transmission delay of a next block of data (with respect to the current one) is estimated and attached to the block of data. The central computer receiving the updated block of data can calculate an expected receiving time of the next block of data accordingly. If the next block of data is not received in due time, the central computer determines a failure of the local computer. The central computer also scans a subset of ports of the local computer, to ascertain whether the problem is due to a temporary unavailability of the application.

Abstract: Embodiments are directed to predicting the health of a computer node using health report data and to proactively handling failures in database services. In an embodiment, a computer system monitors various health indicators for multiple nodes in a database cluster. The computer system accesses stored health indicators that provide a health history for the database cluster nodes. The computer system then generates a health status based on the monitored health factors and the health history. The generated health status indicates the likelihood that the node will be healthy within a specified future time period. The computer system then leverages the generated health status to handle current or predicted failures. The computer system also presents the generated health status to a user or other entity.

The method comprises acquiring brake pedal measurements from a brake pedal sensor, determining a state of the brake pedal sensor, and providing a notification of the state. Each brake pedal measurement comprises a brake pedal deflection amount. The brake pedal sensor test algorithm may be conducted at regular intervals, in preparation for aircraft landing, at the request of a human operator, and the like.

Abstract: Disclosed are methods and apparatus for error handling within jobs that utilize a plurality of tasks for data transfer of individual data records to a storage destination. For each task, one or more failed records may be logged to a file for later insertion. If a high percentage of a task's output (e.g., writes to another data storage system) is determined to be failing, the task short-circuits itself. Each task is also configured to perform checkpoint logging as the task completes work. If the entire job later short-circuits and is to be restarted, the restarted job only repeats a minimal amount of previously completed work for the tasks which have not already completed their data insertions. Together, these techniques can ensure that in the face of periodic failures, the job completes long-running job in a minimal time with minimal effects.

Abstract: A method is provided for detecting when users are being adversely impacted by poor system performance. A system health indicator is determined that is based on the amount of work that is blocked waiting for each of a set of an external events and combined with a heuristic that is based on the number of users waiting for the work to complete.

However, the system health indicator is designed so that an alert is only generated when a significant user base is or will in the near future experience a problem with the system. Furthermore, the system health indicator is designed to vary smoothly to maintain its suitability for the application of predictive technology.

Requests to perform the service may not be transmitted during an exclusion time associated with a service or its corresponding service computer.

Abstract: Disclosed is a data processing system capable of detecting a sign of abnormality in such a manner as to increase the degree of safety and availability of the system. The data processing system uses a prediction circuit that detects a sign of abnormality in accordance with a cumulative history of significant events encountered during the processing of CPUs. The prediction circuit retains latest notification timing information about periodic notification from the CPUs in association with the CPUs, acquires elapsed time from the latest notification timing at predetermined intervals, and successively retains history information corresponding to changes in the elapsed time from a target value in association with the CPUs. When the retained history information reaches a predetermined threshold value, the prediction circuit concludes that there is a sign of abnormality.

Abstract: A method of detecting impending analytical failure in a networked diagnostic clinical analyzer is based upon detecting whether the operation of a particular analyzer is statistically distinguishable based on one or more thresholds. A failure occurs when one or more components or modules of the analyzer fails. A method to detect such an impending failure is disclosed. Baseline data on a pre-selected set of analyzer variables for a population of diagnostic clinical analyzers is used to generate an impending failure threshold. Subsequently, operational data comprising the same pre-selected set of analyzer variables allows generation of a time series of operational statistics. If the operational statistic exceeds the impeding failure threshold in a prescribed manner, an impending analytical failure is predicted. Such detection of impending analytical failures facilitates intelligent scheduling of service for the analyzer in question to maintain high assay throughput and accuracy.

Abstract: Processes in a cluster maintain a historical record of problem events as those events occur in the cluster. The record may describe (a) attributes of each event and (b) the resolution action that was performed to resolve each event. Whenever a new event occurs, a process determines whether any entries in the record reflect occurrences of an event with attributes like those of the new event. If a “matching” entry exists, then the process increments that entry's counter. If the historical record indicates that similar events have previously occurred more than a specified number of times, then the process may select and perform a resolution action that differs from the resolution action that is indicated in the entry. Additionally, patterns in the attributes of a recurring problem may be used to predict when the problem is likely to recur. Preventative actions may be taken to avoid recurrence of the problem.

A warning system evaluates the historical data in the data log to identify one or more devices that have a soft failure condition, wherein an alarm is output for each soft failure identified. A display module combines the historical data from the data log and one or more alarms from the warning system into a single display for review.

Abstract: The network fault manager described herein may include one or more processors configured to detect alarms. For example, the one or more processors may periodically sample rates at which similar events that relate to occurrences on a network arrive, compare the periodically sampled rates to a first threshold, and determine whether a preexisting alarm exists. In response to a number of the periodically sampled rates that exceeded the first threshold within a preceding time window exceeding a second threshold and the preexisting alarm not existing, the one or more processors may assert a first alarm. Otherwise, if the number of periodically sampled rates that exceeded the first threshold within the preceding time window exceeds the second threshold but the preexisting alarm does exist, the one or more processors may maintain the preexisting alarm for a predetermined time period.
