Abstract: Various methods and systems for tracking incomplete purchases in correlation with application performance, such as application errors or crashes, are provided. In this regard, aspects of the invention facilitate monitoring transaction and application error events and analyzing data associated therewith to identify data indicating an impact of incomplete purchases in relation to an error(s) such that application performance can be improved. In various implementations, application data associated with an application installed on a mobile device is received. The application data is used to determine that an error that occurred in association with the application installed on the mobile device correlates with an incomplete monetary transaction initiated via the application. Based on the error correlating with the incomplete monetary transaction, a transaction attribute associated with the error is determined.

Abstract: Techniques for incrementally increasing media size in data storage systems using grid encoded data storage techniques are described herein. A grid of shards is created where each shard of the grid of shards has a first index, a second index and each shard also has an associated storage device configured with a storage capacity that is large enough to store the largest set of data on a shard. Upon determining to replace the storage devices of the grid with storage devices that have a different storage capacity, the storage devices can be incrementally replaced within the grid by first padding each shard of the grid of shards with a set of data values, replacing a data shard storage device with a device of the different storage capacity, and replacing a set of derived shard storage devices with devices of the different storage capacity.

Abstract: In order to perform system-capability testing, an application in an application layer may provide predefined system capabilities and/or requirements of or associated with the application to a communication plugin in a data-link layer, such as availability of communication via a network and/or a latency of the network less than a predefined value. In response, the communication plugin may determine feedback information that specifies whether the predefined system capabilities are available and whether the predefined requirements are satisfied. Then, the communication plugin may provide the feedback information to the application. When the feedback information indicates that a system capability is unavailable, remedial action may be performed. For example, the remedial action may include updating a version of the application, updating a version of the communication plugin, and/or updating a path to a location in a network.

Abstract: The present disclosure provides a system that includes an array of disk drives and a controller communicatively coupled to the array of disk drives. The controller is to identify, within the array of disk drives, a predictive failed disk. The controller also rebuilds data of the predictive failed disk on a spare drive in a regeneration mode and determines a regeneration time baseline. The controller also rebuilds data of the predictive failed disk on the spare drive in a copy mode and determines the copy mode execution time. The controller switches to regeneration mode if the copy mode execution time is greater than the regeneration time baseline.

Abstract: Concepts and technologies are disclosed herein for using diversity to provide redundancy of virtual machines. A server computer that executes an orchestrator application can receive a virtual machine instantiation request. The server computer can analyze the request to determine needs associated with a virtual machine (including a redundancy requirement). The server computer can obtain resource availability data that indicates availability of resources and includes diversity data used to provide diversity-based redundancy of the virtual machine. The server computer can identify a pool of resources and identify, among the pool, two or more resources. The two or more resources can include a most diverse group of resources of the pool of resources and can be identified based upon the diversity data. The server computer can trigger instantiation of the virtual machine and a copy of the virtual machine on the resources.
