    Abstract: 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.

    Abstract: 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.

    Abstract: The present invention is related to a method for providing dynamic indexer discovery. The method comprises receiving, from an index manager, a status indication associated with a plurality of indexers, wherein each of the plurality of indexers indexes events of raw machine-generated data received from a plurality of data collectors. The method further comprises determining a weight associated with each of the plurality of indexers and selecting an indexer from the plurality of indexers. Subsequently, the method comprises allocating data to the indexer in accordance with a respective weight assigned to the indexer and transmitting the allocated data to the indexer.

    Abstract: A processing node selects a first task from a task list and sends, to a task assignment repository, a first write operation with a first task identifier of the first task to assign the first task to the processing node. The processing node detects failure of the first write operation based on the first task already being assigned and selects a second task from the task list. The processing node sends, to the task assignment repository, a second write operation with a second task identifier of the second task to assign the second task to the processing node. The processing node detects success of the second write operation and executes the second task.

    Abstract: A log-to-metrics transformation system includes a log-to-metrics application executing on a processor. The log-to-metrics transformation system receives a format associated with machine data, and further receives, via a first graphical control, a first set of metric identifiers corresponding to a first set of metrics associated with the machine data. The log-to-metrics transformation system generates a first set of mappings between the first set of metric identifiers and a first set of field values included in the machine data. The log-to-metrics transformation system stores the first set of mappings and an association with the format of the machine data. The log-to-metrics transformation system, based on the first set of mappings, causes the first set of field values to be extracted from the machine data. Further, a first metric included in the first set of metrics is determined based on at least a portion of the first set of field values.

    Abstract: 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.
