Abstract: Embodiments of the present disclosure provide solutions for determining an elected search head captain is unqualified for the position, identifying a more qualified search head, and transferring the captain position to the more qualified search head. A method is provided that includes referencing qualification parameters in an elected search head captain, determining whether the newly elected search head captain is qualified for the position based on the parameters, identifying a more qualified search head to be the search head captain if the newly elected search head captain is determined to be unqualified for the position, and transferring the position of captain to the more qualified search head. The qualification parameters may include, for example, a pre-determined static flag set by an administrator of the search environment, and configuration replication status that corresponds to the most recent configuration state of the search head as recorded by the previous search head captain.

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.

Abstract: The present disclosure provides solutions for determining the divergence (delta) between the current and previous reference data structures for mutable data in a search head. A method is provided that includes updating a pre-existing lookup table in a search head, generating a delta file that identifies the divergence between the updated and previous lookup table, and distributing the delta file to other components in the search environment. The compatibility of the delta file is checked with the local instance of the lookup table in each search component, and the lookup table is applied if compatibility is determined. However, if the delta file is determined to not be compatible with the current version of a local lookup table in an indexer, the entire lookup table sent to the requesting indexer instead.

Abstract: Systems and methods are disclosed for monitoring features of a computing device of a distributed computing system using a self-monitoring module. The self-monitoring module can include multiple feature-specific monitoring modules and one or more parent nodes for the feature-specific monitoring modules. A feature-specific monitoring module can identify or detect a fault status change, such as a fault condition or fault resolution, for one or more features. Based on the identified fault conditions or fault resolutions, the feature-specific monitoring module can determine an internal status and communicate an updated status to a parent node.

Abstract: 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.

Abstract: A method of dynamic cluster manager failover includes routing data traffic associated with managing a plurality of indexers in a cluster to a first cluster manager, wherein the first cluster manager is associated with an active role and is operable to manage the plurality of indexers in the cluster. The method also includes transmitting periodic heartbeat request messages from a second cluster manager of the cluster to the first cluster manager, wherein the second cluster manager is associated with a standby role. Further, the method includes detecting, at the second cluster manager, a loss of heartbeat response messages from the first cluster manager. Also, the method includes receiving information from a set of indexers regarding a status of the first cluster manager and in response to a determination that the status of the first cluster manager is offline, promoting the second cluster manager to switch over to the active role.

Abstract: A computer-implemented method of providing for dynamic cluster manager failover includes routing data traffic associated with managing network components in a cluster to an active cluster manager, where the active cluster manager manages a plurality of network components in the cluster. The method also includes transmitting periodic heartbeat request messages from a standby cluster manager to the active cluster manager. Further, the method includes detecting a loss of heartbeat response messages from the active cluster manager, where the heartbeat response messages are transmitted from the standby cluster manager to the active cluster manager in response to the periodic heartbeat request messages. The method also includes promoting the standby cluster manager to an active role and re-routing the data traffic associated with managing the network components to the currently active cluster manager.
