ELK 是 Elasticsearch、Logstash、Kibana 的简称，是近乎完美的开源实时日志分析平台
这三者是日志分析平台的核心组件，而并非全部

Elasticsearch：实时全文搜索和分析引擎，提供搜集、分析、存储数据三大功能，具有分布式，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，自动搜索负载等特点

Logstash：它支持几乎任何类型的日志，包括系统日志、错误日志和自定义应用程序日志，它可以从许多来源接收日志，这些来源包括 syslog、消息传递（例如 RabbitMQ）和 JMX，它能够以多种方式输出数据，包括电子邮件、websockets 和 Elasticsearch

Kibana：基于 Web 的图形界面，用于搜索、分析和可视化存储在 Elasticsearch 指标中的日志数据，它利用 Elasticsearch 的 REST 接口来检索数据，不仅允许用户创建他们自己的数据的定制仪表板视图，还允许他们以特殊的方式查询和过滤数据，Kibana 可以为 Logstash 和 Elasticsearch 提供友好的日志分析 web 界面，可以帮助你汇总、分析和搜索重要数据日志
