Abstract: Techniques are presented for recommending queries to search log information. The system provides useful insights and recommendations based on user needs and queries by utilizing the user context, with information about the user activities (e.g., recent alerts) and the user configuration in the system (e.g., applications configured by the user), to provide recommendations. There may not be enough context for a new user to provide good recommendations, so the system determines the context based on the activities of other users, such as more experienced users or users investigating the same type of problem. Based on the context, the user recommends natural language queries (NLQ) or system queries to accelerate the search process and assist the user during an investigation. Further, NLQs may be converted to complex search queries that use the search query language, and the NLQs may also be used as part of the context for the subsequent recommendations.

Abstract: Data storage optimization techniques determine predicted values for I/O statistics using an ARIMA (auto-regressive integrated moving average) model. The ARIMA model may be used to capture periodic patterns and trends of workload I/O access to predict the future load demand. A current set of I/O statistics is collected for a current time period T. Using the current set and one or more ARIMA models, a predicted set of I/O statistics is determined for a next time period T+1. Each of the ARIMA models is characterized by model parameters including P denoting a number of auto-regressive terms, D denoting a number of nonseasonal difference needed for stationarity, and Q denoting a number of lagged forecast errors of prediction. A data storage optimizer may determine one or more data portions for movement from a current storage tier to a target storage tier using the predicted set of I/O statistics.

Abstract: A flash-optimized, log-structured layer of a file system of a storage input/output (I/O) stack executes on one or more nodes of a cluster. The log-structured layer of the file system provides sequential storage of data and metadata (i.e., a log-structured layout) on solid state drives (SSDs) of storage arrays in the cluster to reduce write amplification, while leveraging variable compression and variable length data features of the storage I/O stack. The data may be organized as an arbitrary number of variable-length extents of one or more host-visible logical units (LUNs) served by the nodes. The metadata may include mappings from host-visible logical block address ranges (i.e., offset ranges) of a LUN to extent keys, as well as mappings of the extent keys to SSD storage locations of the extents. The storage location of an extent on SSD is effectively “virtualized” by its mapped extent key (i.e.

Any later transactions are discovered and used to update the recovered metadata so that the metadata correctly represents the stored data.

Abstract: A logging system includes an event receiver and a storage manager. The receiver receives log data, processes it, and outputs a data “chunk.” The manager receives data chunks and stores them so that they can be queried. The receiver includes buffers that store events and a metadata structure that stores metadata about the contents of the buffers. The metadata includes a unique identifier associated with the receiver, the number of events in the buffers, and, for each “field of interest,” a minimum value and a maximum value that reflect the range of values of that field over all of the events in the buffers. A chunk includes the metadata structure and a compressed version of the contents of the buffers. The metadata structure acts as a search index when querying event data. The logging system can be used in conjunction with a security information/event management (SIEM) system.

Abstract: Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application.

The refined log data assists a user in evaluating an enterprise application.

Abstract: This patent application relates to enhanced logical recovery techniques for redo recovery operations of a system with an unbundled storage engine. These techniques can be implemented by utilizing an enhanced logical recovery approach in which a dirty page table (DPT) is constructed based on information logged during normal execution. The unbundled storage engine can include a transaction component (TC) that is architecturally independent of a data component (DC). These techniques can enhance redo recovery operations by mitigating the resources needed to determine whether previously executed operations sent from the TC to the DC are to be repeated in response to a recovery-initiating event. This can include using the DPT to avoid fetching every data page corresponding to every previously executed operation received by the DC during recovery and/or pre-fetching data pages and/or index pages that correspond to PIDs in the DPT.
