摘要： Embodiments are directed towards managing and tracking item identification of a plurality of items to determine if an item is a new or existing item, where an existing item has been previously processed. In some embodiments, two or more item identifiers may be generated. In one embodiment, generating the two or more item identifiers may include analyzing the item using a small item size characteristic, a compressed item, or for an identifier collision. The two or more item identifiers may be employed to determine if the item is a new or existing item. In one embodiment, the two or more item identifiers may be compared to a record about an existing item to determine if the item is a new or existing item. If the item is an existing item, then the item may be further processed to determine if the existing item has actually changed.

摘要： 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.

US10268755B2 Systems and methods for providing dynamic indexer discovery 有权

摘要： The present disclosure is directed to providing dynamic indexer discovery. An index manager, which may also be known as a cluster master, is configured to track the statuses and capabilities of indexers and provide the statuses and capabilities obtained from the indexers to data collectors, such as forwarders. The data collectors may use the statuses and capabilities associated with the indexers to load balance transmission of data to the indexers. Dynamic indexer discovery may eliminate the need to manually reconfigure data collectors when the status of an indexer changes because the information may be obtained from the index manager without the need to reinitialize the data collectors.

摘要： In a computer-implemented method for configuring a distributed computer system comprising a plurality of nodes of a plurality of node classes, configuration files for a plurality of nodes of each of the plurality of node classes are stored in a central repository. The configuration files include information representing a desired system state of the distributed computer system, and the distributed computer system operates to keep an actual system state of the distributed computer system consistent with the desired system state. The plurality of node classes includes forwarder nodes for receiving data from an input source, indexer nodes for indexing the data, and search head nodes for searching the data. Responsive to receiving changes to the configuration files, the changes are propagated to nodes of the plurality of nodes impacted by the changes based on a node class of the nodes impacted by the changes.

摘要： Embodiments are directed towards a dynamic change evaluation mechanism, whereby items having a detected possible change are scheduled for re-evaluation for possible changes at a higher frequency than items detected to not have previously changed, while those items detected as not to have changed are dynamically scheduled for re-evaluation based on an evaluation backlog that may be in turn based, in part, on a time from when an item is assigned an expiration time to when the item is evaluated. In one embodiment, a possibly changed item may be assigned a new expiration time independent of the evaluation backlog. In another embodiment, if no change is detected, then the item may be assigned a new expiration time as a function of a previous expiration time and on the evaluation backlog.

摘要： Embodiments are directed towards managing within a cluster environment having a plurality of indexers for data storage using redundancy the data being managed using a generation identifier, such that a primary indexer is designated for a given generation of data. When a master device for the cluster fails, data may continue to be stored using redundancy, and data searches performed may still be performed.

摘要： According to various embodiments, techniques are described for managing data within a multi-site clustered data intake and query system. A data intake and query system as described herein generally refers to a system for collecting, retrieving, and analyzing data. In this context, a clustered data intake and query system generally refers to a system environment that is configured to provide data redundancy and other features that improve the availability of data stored by the system. For example, a clustered data intake and query system may be configured to store multiple copies of data stored by the system across multiple components such that recovery from a failure of one or more of the components is possible by using copies of the data stored elsewhere in the cluster.
