Logstash 简介

Logstash 是一个数据流引擎:

它是用于数据物流的开源流式 ETL(Extract-Transform-Load)引擎

在几分钟内建立数据流管道

具有水平可扩展及韧性且具有自适应缓冲

不可知的数据源

具有200多个集成和处理器的插件生态系统

使用 Elastic Stack 监视和管理部署

Logstash 是如何工作的?

Laravel

Logstash 包含3个主要部分: 输入(inputs),过滤器(filters)和输出(outputs)。 你必须定义这些过程的配置才能使用 Logstash,尽管不是每一个都必须的。在有些情况下,我们可以甚至没有过滤器。在过滤器的部分,它可以对数据源的数据进行分析,丰富,处理等等。

安装

docker pull logstash:7.12.1
----------------------------------
vim logstash.conf

配置文件如下
