前言

相信作为一个资深的搬砖人，在处理问题的时候免不了查看应用系统日志，且可以根据这个日志日志精准、快速的解决实际的问题。一般情况下我们的系统日志都放置在包的运行目录下面，非常不便于查看和分类。那么。今天我们就引入ELK的日志处理架构来解决它。

技术积累

ELK组成及功能

ELK是logstash、elasticsearch、kibana的简称，和其名字一样，elk架构就是将这三个中间件进行整合搭建一个日志系统。

首先我们应用系统集成logstash客户端并采集日志上传到logstash服务端进行过滤、转换，转换后的日志写入elasticsearch，es的强大功能提供数据存储，分词和倒排索引提升查询效率；最后的kibana直接是渲染日志数据的分析和可视化平台。

框架搭建基础

为方便我们架构的搭建，我们用docker-compose进行容器化编排，只要保存elk三个组件同网络下它们就能够根据服务名进行通讯。

当然，对于向外暴露的接口我们仅仅需要暴露logstash的进行数据上传，es的进行数据外部查询即可。每个应用服务都必须有自己的logstash配置，在配置中提供输入、输出路径和过滤参数，对于的端口我们也需要向外暴露以便于数据的上传。

写在最后

ELK环境部署并采集springboot项目日志还是比较简单，我们只需要用docker容器化技术搭建起elk框架，然后在自己的项目中进行数据采集上传即可。当然对于elk组成元素的logstash、elasticsearch、kibana还是需要一些基础的了解，方便在实战的时候进行操作。文章来源地址https://www.toymoban.com/news/detail-582472.html
