  • Publication number: 20190095062
    Abstract: Embodiments include generating data models that may give semantic meaning for unstructured or structured data that may include data generated and/or received by search engines, including a time series engine. A method includes generating a data model for data stored in a repository. Generating the data model includes generating an initial query string, executing the initial query string on the data, generating an initial result set based on the initial query string being executed on the data, determining one or more candidate fields from one or results of the initial result set, generating a candidate data model based on the one or more candidate fields, iteratively modifying the candidate data model until the candidate data model models the data, and using the candidate data model as the data model.

  • Patent number: 10235345
    Abstract: A method, system, and processor-readable storage medium are directed towards calculating approximate order statistics on a collection of real numbers. In one embodiment, the collection of real numbers is processed to create a digest comprising hierarchy of buckets. Each bucket is assigned a real number N having P digits of precision and ordinality O. The hierarchy is defined by grouping buckets into levels, where each level contains all buckets of a given ordinality. Each individual bucket in the hierarchy defines a range of numbers—all numbers that, after being truncated to that bucket's P digits of precision, are equal to that bucket's N. Each bucket additionally maintains a count of how many numbers have fallen within that bucket's range. Approximate order statistics may then be calculated by traversing the hierarchy and performing an operation on some or all of the ranges and counts associated with each bucket.

  • Publication number: 20190042610
    Abstract: A method and system for managing searches of a data set that is partitioned based on a plurality of events. A structure of a search query may be analyzed to determine if logical computational actions performed on the data set is reducible. Data in each partition is analyzed to determine if at least a portion of the data in the partition is reducible. In response to a subsequent or reoccurring search request, intermediate summaries of reducible data and reducible search computations may be aggregated for each partition. Next, a search result may be generated based on at least one of the aggregated intermediate summaries, the aggregated reducible search computations, and a query of adhoc non-reducible data arranged in at least one of the plurality of partitions for the data set.

  • Patent number: 10162863
    Abstract: A method, system, and processor-readable storage medium are directed towards generating a report derived from data, such as event data, stored on a plurality of distributed nodes. In one embodiment the analysis is generated using a “divide and conquer” algorithm, such that each distributed node analyzes locally stored event data while an aggregating node combines these analysis results to generate the report. In one embodiment, each distributed node also transmits a list of event data references associated with the analysis result to the aggregating node. The aggregating node may then generate a global ordered list of data references based on the list of event data references received from each distributed node. Subsequently, in response to a user selection of a range of global event data, the report may dynamically retrieve event data from one or more distributed nodes for display according to the global order.

  • Publication number: 20180246918
    Abstract: Embodiments are directed are towards the transparent summarization of events. Queries directed towards summarizing and reporting on event records may be received at a search head. Search heads may be associated with one more indexers containing event records. The search head may forward the query to the indexers the can resolve the query for concurrent execution. If a query is a collection query, indexers may generate summarization information based on event records located on the indexers. Event record fields included in the summarization information may be determined based on terms included in the collection query. If a query is a stats query, each indexer may generate a partial result set from previously generated summarization information, returning the partial result sets to the search head. Collection queries may be saved and scheduled to run and periodically update the summarization information.

  • Publication number: 20180218037
    Abstract: Embodiments of the present disclosure provide techniques for using an inverted index in a pipelined search query. A field searchable data store is provided that comprises a plurality of event records, each event record comprising a time-stamped portion of raw machine data. Responsive to the reciept of an incoming search query, the search engine accesses an inverted index, wherein each entry in the inverted index comprises at least one field name, a corresponding at least one field value and a reference value associated with each field name and value pair that identifies a location in the data store where an associated event record is stored. Once the inverted index is accessed, it can be used to filter out a subset of the plurality of event records, wherein the subset comprises one or more event records with corresponding reference values in the inverted index.

  • Publication number: 20180089290
    Abstract: The disclosed embodiments include a method performed by a data intake and query system. The method includes ingesting each metric including at least one key value and a measured value taken of a computing resource, and storing each metric in an index of a metrics store, where the index defines at least one dimension populated with the at least one key value and a measure populated with the measured value. The method further includes cataloging metadata in a metrics catalog, where the metadata is related to the metrics stored in the metrics store, performing an analysis of metrics data included in the metrics store and/or the metrics catalog to obtain results, and causing display of the results or an indication of the results on a display device.

  • Publication number: 20180089289
    Abstract: The disclosed embodiments include a method performed by a data intake and query system. The method includes receiving a real-time search query including search criteria, and receiving a stream of metrics, where each metric includes a measured value taken of a computing device. The method further includes filtering the metrics to obtain filtered metrics satisfying the search criteria, creating an in-memory summarization data structure based on the filtered metrics, communicating the summarization data to a search head, and providing search results including the summarization data, where the summarization data or data indicative of the summarization data is displayed on a display of a display device.

  • Patent number: 9817862
    Abstract: Embodiments are directed towards determining and tracking metadata for the generation of visualizations of requested data. A user may request data by providing a query that may be employed to search for the requested data. The query may include a plurality of commands, which may be employed in a pipeline to perform the search and to generate a table of the requested data. In some embodiments, each command may be executed to perform an action on a set of data. The execution of a command may generate one or more columns to append and/or insert into the table of requested data. Metadata for each generated column may be determined based on the actions performed by executing the commands. The table of requested data and the column metadata may be employed to generate and display a visualization of at least a portion of the requested data to a user.
