Abstract: A Data Storage Device (DSD) includes at least one disk and at least one memory storing an active Primary defect List (P-List) indicating defective sectors identified during formatting, a Grown defect List (G-List) indicating defective sectors identified after formatting, and an inactive P-List including entries for accepting entries from the G-List. Entries of the G-List are merged into the P-List by successively reassigning descending sets of logical addresses from respective sets of sectors to a temporary storage area and reserving at least a portion of the sectors for a set of shifting P-List entries. Entries of the shifting P-List entries are retained in the inactive P-List for grown defect sectors, and the set of shifting P-List entries is reduced by the number of retained entries before shifting toward a next set of sectors. The descending sets of logical addresses are reassigned from the temporary storage area back to non-defect sectors.

Abstract: Embodiments of the present disclosure are directed to sampling telemetric values of computing devices in an efficient manner. Generally speaking, embodiments described herein are directed to sampling counters and gauges of computing devices in a network, data center, etc. in a way that reduces redundant and non-informative signals, while being adaptive when sampling with high granularity desirable. According to one embodiment, counters can be correlated with each other, sharing residual information, and therefore, sampling only a subset of them, or a “representative” can be sufficient in representing a current state. When there is a notable change in the representative, the telemetry sampling procedure can increase its granularity and sample not only the representative but also the underlying group of telemetric values.

Abstract: A power state framework executes a workload in supported computing device types and configurations during a sequence of power state transitions to simulate user experiences. Workloads can be combined, e.g., default workload plus add-on workload(s). Device states are monitored, collected, reported, and analyzed to identify faults, which are prioritized for repair, e.g., based on the projected impact of the faults on users, e.g., if the users were to experience the faults. Computing device states include states of attached peripheral devices and wireless or wired connectivity before and after power state transitions. Device state indicates device stability throughout supported device power state transitions. Devices under test can be on debuggers during execution of workload and power state transitions.

Abstract: A logging system is disclosed, which is set with a primary filtering level and a secondary filtering level. A log message is saved in a log stream with a log level higher than or equal to the secondary filtering level in a buffer region. In response to a log filtering flag being set to the primary filtering level, a log message in the buffer region is output with the log level higher than or equal to the primary filtering level to a target region. In addition, all log messages in the buffer region to the target region are output in response to the log filtering flag being set to the secondary filtering level. Beneficially, unnecessary log messages are avoided from being output to the target region, while ensuring that required log messages are output to the target region, thereby improving the quality of log files.

Abstract: An approach is provided for controlling an alert suppression policy. Using historical training data and for a time period, an expected alert reduction for an alert suppression policy (ASP) is computed. The ASP is recommended for an information technology (IT) environment. During runtime and for the time period, an observed alert reduction for the ASP is computed. A visualization of a benefit of the ASP is generated by generating a visualization of a comparison of the observed alert reduction and the expected alert reduction. An explanation of why the ASP is recommended for the IT environment is generated by determining persistent regions for respective event time series from the historical training data and generating a visualization of the persistent regions on a time graph that includes a duration and a number of events for a given persistent region. Each event time series corresponds to a given resource for the ASP.

Abstract: Accuracy, efficiency, and speed improvements for error alerting are provided herein, particularly in the context of error detection and alerting. There are provided systems and methods for scalable error alerts threshold based on conversion metrics for data processing flows. A service provider may utilize different computing services for data processing to provide different computing services to users, such as via websites and/or applications of the service provider. Due to timeouts, failures, and other errors, users may be unable to complete a data processing flow. To provide dynamic error alerting, thresholds for reporting of the errors may be adjusted based on conversion metrics for users abandoning the processing flow at different steps. A threshold for a number of users that fail to complete the flow at certain steps may be adjusted to account for users that may abandon due to errors or other reasons.
