Abstract: A method for troubleshooting abnormal behavior of an application hosted on a networked computer system. The method may be implemented by a root cause analyzer. The method includes tracking a single application performance metric across all the clients of an application hosted on a networked computer system and analyzing an aggregated application based on the single application metric. The method involves determining outlier client attributes associated with an abnormal transaction of the application and ranking the outlier client attributes based on comparisons of historical and current abnormal transactions. The method associates one or more of the ranked outlier client attributes with the root cause of the current abnormal transaction. Association rule learning is used to associate one or more of the ranked outlier client attributes with the root cause.

Abstract: The disclosure describes techniques that enable detection of memory leaks of software executing on devices within a computer network. An example network device includes memory and processing circuitry. The processing circuitry monitors a usage of the memory by a software component operating within the network device. The processing circuitry periodically determines a memory growth pattern score for the software component based on the usage of the memory. The processing circuitry also predicts whether the user-level process is experiencing a memory leak based on the memory growth pattern score. The processing circuitry applies confirmation criteria to current memory usage of the software component to confirm that the software component is experiencing the memory leak. When the software component is experiencing the memory leak, the processing circuitry generates an alert.

Abstract: At least one processing device is configured to detect a failure event impacting at least a first storage node of a plurality of storage nodes of a distributed storage system, and responsive to the detected failure event, to modify an input-output (IO) shaping mechanism in each of the storage nodes in order to at least temporarily reduce a total number of IO operations that are concurrently processed in the distributed storage system. For example, modifying an IO shaping mechanism in each of the storage nodes illustratively comprises transitioning the IO shaping mechanism in each of the storage nodes from a first operating mode to a second operating mode that is different than the first operating mode. The second operating mode of the IO shaping mechanism illustratively has a relatively faster responsiveness to changes in IO operation latency as compared to the first operating mode of the IO shaping mechanism.

Abstract: An actuator to execute on a server may be automatically selected based on risk of failure and damage to the server. Requirement specification and environment parameters may be received. A subset of actuators may be selected based on a risk threshold from an actuator catalog database storing actuator information and actuator risk metadata associated with a plurality of actuators. The actuator risk metadata may be augmented with risk information. A ranked list of the subset of actuators may be generated based on the actuator risk metadata associated with each actuator in the subset. An actuator in the ranked list may be executed on the server.

The method, performed by a processing unit of a bridge integrate circuit (IC), includes: determining whether a temperature of a motherboard has exceeded a threshold through a temperature sensor IC after receiving a host read or write command from a host side; requesting a flash memory card to enter a sleep state when the temperature of the motherboard has exceeded the threshold; and instructing the flash memory card to perform an operation corresponding to the host read or write command when the temperature of the motherboard hasn't exceeded the threshold. The bridge IC and the temperature sensor IC are disposed on the motherboard, the flash memory card is inserted into a card slot on the motherboard, and the bridge IC is coupled to the temperature sensor IC and the flash memory card through a circuit of the motherboard.

Abstract: A medical device arrangement (100) tests processing of data sets to be processed during operation of the medical device arrangement. The arrangement includes a data interface (110), analysis modules (120) and a test module (130). The analysis modules process a received medical data set (105). Each analysis module (122, 123, 124) forms a processing instance (390) for the medical data set or for the medical data set (125, 125?) already preprocessed by at least one other analysis module. The test module outputs a test data set (132) to one of the analysis modules during operation such that this analysis module processes the test data set in the same manner as the medical data set. The test module compares a correspondingly outputted, processed test data set (134) with a reference result (136) associated with the test data set and determines a test result (137) based on this comparison.

Abstract: An apparatus and a method of operating a data processing apparatus, and simulators thereof, are disclosed. Data processing circuitry performs data processing operations in response to instructions, where some sets of instructions may be defined as a transaction which are to be performed atomically with respect to other operations performed by the data processing circuitry. When a synchronous exception occurs during a transaction the transaction is aborted and an exception counter is incremented. When the counter reaches a threshold value a transaction failure signal is generated, allowing, if appropriate a response to this number of exceptions causing transaction aborts to be carried out.

Abstract: Methods, systems, and devices for persistent health monitoring for volatile memory devices are described. A memory device may determine that an operating condition associated with an array of memory cells on the device, such as a temperature, current, voltage, or other metric of health status is outside of a range associated with a risk of device degradation. The memory device may monitor a duration over which the operating condition is outside of the range, and may determine whether the duration satisfies a threshold. In some cases, the memory device may store an indication of when (e.g., each time) the duration satisfied the threshold. The memory device may store the one or more indications in one or more non-volatile storage elements, such as fuses, which may enable the memory device to maintain a persistent indication of a cumulative duration over which the memory device is operated with operating conditions outside of the range.

Abstract: Motherboard connector failures can be predicted. An embedded controller can be employed on the motherboard to monitor when devices are connected to and disconnected from the motherboard's connectors. The embedded controller can maintain an event log and connector information in which it counts the number of times a device is connected to/disconnected from a connector. The BIOS can leverage the event log and the connector information to notify an end user to take action to correct or prevent possible corrosion. Training records may also be employed to predict connector failure. The training records can track and maintain baseline and periodic device training attributes. When the periodic training attributes deviate from the baseline training attributes, an end user can be notified to take action to remove corrosion.
