ELK由Elasticsearch、Logstash和Kibana三部分组件组成；
Elasticsearch是个开源分布式搜索引擎，它的特点有：分布式，零配置，自动发现，索引自动分片，索引副本机制，restful风格接口，多数据源，自动搜索负载等。
Logstash是一个完全开源的工具，它可以对你的日志进行收集、分析，并将其存储供以后使用
kibana 是一个开源和免费的工具，它可以为 Logstash 和 ElasticSearch 提供的日志分析友好的 Web 界面，可以帮助您汇总、分析和搜索重要数据日志。
四大组件
Logstash: logstash server端用来搜集日志；
Elasticsearch: 存储各类日志；
Kibana: web化接口用作查寻和可视化日志；
Logstash Forwarder: logstash client端用来通过lumberjack 网络协议发送日志到logstash server；
