    • A scheduler manages execution of a plurality of data-collection jobs, assigns individual jobs to specific forwarders in a set of forwarders, and generates and transmits tokens (e.g., pairs of data-collection tasks and target sources) to assigned forwarders. The forwarder uses the tokens, along with stored information applicable across jobs, to collect data from the target source and forward it onto an indexer for processing. For example, the indexer can then break a data stream into discrete events, extract a timestamp from each event and index (e.g., store) the event based on the timestamp. The scheduler can monitor forwarders' job performance, such that it can use the performance to influence subsequent job assignments. Thus, data-collection jobs can be efficiently assigned to and executed by a group of forwarders, where the group can potentially be diverse and dynamic in size.
    • 调度器管理多个数据收集作业的执行,向一组转发器中的特定转发器分配各个作业,并且生成并发送令牌(例如,数据收集任务对和目标源对)到分配的转发器。 转发器使用令牌,以及适用于作业的存储信息,从目标源收集数据,并将其转发到索引器进行处理。 例如,索引器然后可以将数据流中断为离散事件,从每个事件中提取时间戳并基于时间戳索引(例如,存储)事件。 调度程序可以监视转发器的作业性能,使其可以使用性能来影响后续的作业分配。 因此,数据收集作业可以被有效地分配给一组转发器并且由一组转发器执行,其中该组可以在大小上潜在地多样化和动态化。
