filebeat是用于"转发"和"集中日志数据"的轻量级数据采集器。 filebeat会监视指定的日志文件路径，收集日志事件并将数据转发到elasticsearch，logstash，redis，kafka存储服务器。 当您要面对成百上千，甚至成千上万的服务器，虚拟机的容器生成的日志时，请告别SSH吧。 Filebeat将为您提供一种轻量级方法，用于转发和汇总日志与文件，让简单的事情不再繁杂。
| Filebeat的组件 Filebeat包含两个主要组件，input(输入)和Harvester(收割机)，两个组件协同工作将文件的尾部最新数据发送出去。 Harveste组件: 负责逐行读取单个文件的内容,然后将内容发送到输出。 input组件: 输入负责管理收割机并找到所有要读取的源。该参数的源文件路径需要使用者手动配置。 Spooler(缓冲区): 将Harvester组件采集的数据进行统一的缓存,并发往目的端,可以是 Elasticsearch, Logstash , kafka 和 Redis 等。 | Filebeat工作原理 filebeat工作流程如下: 1、filebeat启动后，filebeat通过Input读取指定的日志路径; 2、为该文件日志启动收割进程harvester,每个收割进程读取一个日志文件的新内容,并发送这些新的日志数据到处理程序spooler; 3、spooler会集合这些事件,最后filebeat会发送集合的数据到你指定的位置。 Filebeat如何保持文件的状态? Filebeat保持每个文件的状态,并经常将状态刷新到注册表文件(data/registry/filebeat/log.json)中的磁盘。 该状态用于记住收割机读取的最后一个偏移量,并确保发送所有日志行。 Filebeat如何确保至少一次交付? Filebeat保证事件将至少传送到配置的输出一次并且不会丢失数据。 Filebeat能够实现这种行为，因为它将每个事件的传递状态存储在注册表文件中。
