Abstract: Aspects of the technology provide solutions for determining a time period (“epoch”) required to monitor or analyze a tenant network. Some implementations of the technology include a process for making automatic epoch determinations, which includes steps for identifying one or more network parameters for a tenant network, analyzing the tenant network using the network parameters to discover one or more configuration settings of the tenant network, and determining a first epoch for the tenant network, the first epoch corresponding with a period of time to complete analysis of the tenant network using the network parameters. In some aspects, the process can further include steps for generating a tenant profile for the tenant network, the tenant profile based on the network parameters, the first epoch, and the one or more configuration settings of the tenant network. Systems and machine-readable media are also provided.

Abstract: Systems, methods, and computer-readable media for aggregating and presenting network events in a network environment. In some embodiments, a system can maintain event correlation rules for aggregating \network events occurring in a network based on characteristics of previously occurring network events. Network events occurring in the specific network environment can be identified. The network events can be aggregated to form an aggregated network event using the event correlation rules maintained based on the characteristics of previously occurring network events. The aggregated network event can subsequently be presented to a user.

Abstract: Systems, methods, and computer-readable media for discovering a network's topology and health. In some examples, a system can obtain, from at least one of a plurality of controllers on a network, a logical model of the network, the logical model including configurations of one or more objects defined for the network. Based on the logical model, the system can identify a respective location of the plurality of controllers in the network and a plurality of nodes in a fabric of the network. Based on the respective location of the plurality of controllers and plurality of nodes, the system can poll the plurality of controllers and plurality of nodes for respective status information, and determine a health and topology of the network based on the logical model, the respective location, and respective status information.

Abstract: According to some embodiments, a system comprises a computer system comprising a processing unit, an interrupt controller, an internal watchdog, and a computer system reset interface. The system further comprises a watchdog controller comprising a secondary watchdog timer. Expiry of the computer system internal watchdog triggers the interrupt controller to cause the processing unit to collect debug information and triggers the watchdog controller to start a secondary watchdog timer. Expiry of the secondary watchdog timer triggers the watchdog controller to reset the computer system.

Abstract: Aspects of the technology provide systems and methods for interleaving a processing task in a network monitoring appliance. A process of the technology could include steps for identifying operators in the network monitoring appliance, wherein the operators are sequentially arranged to form a processing pipeline, determining an epoch for the processing pipeline, wherein the epoch corresponds with a time duration required for a processing task to traverse the pipeline, and determining a time window in which a supplemental processing task can be interleaved into the processing pipeline, wherein the time window is based on the epoch. Machine-readable media are also provided.

Abstract: A system and method for parallel file system traversal using multiple job executors is disclosed. The system includes a pool of job executors, a job queue, and a trigger tracker. An object, representative of a node in the filesystem, is added (i.e., pushed) to the job queue for processing by an job executor. The job queue assigns (i.e., pops) objects to job executors in accordance to a LIFO (Last In First Out) ordering. Then the job executor performs an action such as copy. In one embodiment, the trigger tracker follows the processing of a child nodes to a particular child node. Thus, the filesystem is being traversed by several job executors at the same time.

Abstract translation: 公开了一种使用多个作业执行器并行文件系统遍历的系统和方法。 该系统包括一组作业执行器，一个作业队列和一个触发器跟踪器。 代表文件系统中的节点的对象被添加（即被推送）到作业队列以供作业执行器处理。 作业队列根据LIFO（先进先出）排序将（即弹出）对象分配给作业执行器。 然后，作业执行器执行诸如复制的操作。 在一个实施例中，触发跟踪器遵循对特定子节点的子节点的处理。 因此，文件系统同时被多个作业执行器遍历。
