Abstract: A storage system has a plurality of storage nodes having equal non-volatile storage capacity that is subdivided into equal size cells. Host application data that is stored in the cells is protected using RAID or EC protection groups each having members stored in ones of the cells and distributed across the storage nodes such that no more than one member of any single protection group is stored by any one of the storage nodes. Spare cells are maintained for rebuilding protection group members of a failed one of the storage nodes on remaining non-failed storage nodes so full data access is possible before replacement or repair of the failed storage node.

Abstract: Systems and methods for selective rebuild of interrupted data storage devices in storage arrays are described. A controller determines an operating interruption of a data storage device in a redundant array of independent disks (RAID) configuration. In response to the interruption, the controller determines a last block time value for the last successfully stored RAID block in the interrupted storage device and one or more incomplete RAID stripes that the interrupted storage device did not complete. The controller then selectively rebuilds the incomplete RAID stripes from the other storage devices in the RAID configuration.

The electronic device includes a plurality of software modules, each software module controlling functions of the electronic device. Each of a plurality of failure events are associated in advance with one or more of the software modules. A current event is detected on the electronic device that corresponds to a matching failure event of the plurality of failure events. A predetermined logging level is automatically enabled for the one or more of the software modules associated with the matching failure event at the time of the detected current event. Log messages are captured at the predetermined logging level for the one or more of the software modules for which the predetermined logging level has been automatically enabled. The predetermined logging level is automatically disabled when the current event has ended.

Abstract: An error incident is determined to have occurred on an electronic device. Responsive to the error incident, a remote error logging system is queried for reports of the error incident by one or more additional electronic devices. The error incident is determined to have or have not been reported by the one or more additional electronic devices. A report of the error incident is transmitted to the remote error logging system based on the determination. An adjustment to the electronic device is applied to resolve the error incident. The adjustment is, for example, an amendment to the behavior of a component of the electronic device where the error incident occurred.

Abstract: Arrangements for providing API failure detection and processing are provided. In some aspects, call logs including calls made to one or more APIs as well as a response code for each call may be received and a severity for each API may be determined. For instance, an API having a third severity may be detached from an associated application to disable functionality associated with that API. If an API is assigned a second severity, additional calls may be made to the API to confirm that the API is actually failing. The results of the additional calls may be analyzed and if a sufficient number of failures are detected, an instruction to detach the API may be generated and transmitted. In some arrangements, the error causing the failure may be remedied and the API may be reattached to the application.

Abstract: Automated methods and systems for identifying problems associated with objects of a data center are described. Automated methods and systems are performed by an operations management server. For each object, the server determines a baseline distribution from historical events that are associated with a normal operational state of an object. The server determines a runtime distribution of runtime events that are associated with the object and detected in a runtime window of the object. The management server monitors runtime performance of the object while the object is running in the datacenter. When a performance problem is detected, the management server determines a root cause of a performance problem based on the baseline distribution and the runtime distribution and displays an alert in a graphical user interface of a display.

Abstract: The described technology is generally directed towards processing time series (e.g., device telemetry) data, including identifying missing data (gaps in the time series data), and delayed data. The time series data are converted to ternary data, e.g., zero if timely, one if delayed or two if missing, and counts are obtained for each. If the missing data and/or delayed counts are significant, e.g., exceed a threshold percentage of the total data, the time series data indicates a problem that can be narrowed down to a more specific cause. For example, the time series data can be filtered by customer products/offers and customer locations, and if a filtered dataset's ternary data are similar to the problematic data, as determined via unsupervised clustering as similarity data (occurring at a similar time), the potential problem or problems can be narrowed to a potential cause based on that filtered dataset's similarity.

Abstract: A system includes a data store and a data management server. The data store stores a plurality of backup snapshots that capture states of a device at different times. The data management server receives a request to restore the device that is potentially malware affected. The data management server retrieves a first backup snapshot of the device. The data management server determines that a first file stored in the first backup snapshot is malware affected. The data management server checks one or more corresponding versions of the first file captured in one or more previous backup snapshots to identify a clean version of the first file. The data management server determines that a second file stored in the first backup snapshot is clean. The data management server restores data in the device.
