1.日志内容样式

目前所接触到的日志一种是网页请求日志，一种是埋点日志，一种后端系统日志。

1.1请求日志

请求日志是用户访问网站时，打开网址或点击网站上了项目元素时，向服务器发送或提交的资源请求。

1.2埋点日志

埋点日志是电商网站采用的技术手段，当用户浏览曝光的商时，主动记录曝光的商品列表、停留时间、点击的商品、点击的组件等信息，服务运营，优化商城布局，常见的埋点日志有浏览、点击、曝光日志。

点击、曝光的日志内容与浏览的类似，根据埋点需求不同，采集记录的数据略有不同，记录的核心内容就是body里的内容。

埋点日志是根据需求设计记录的内容，格式齐整，内容规范，一般使用Hive-正则即可进行过滤入库，像这个浏览日志，只需要创建一张表，指定以下正则格式，即可入库使用日志：

'input.regex'='([0-9\\.\\- :,]+) \\- site: ([\\w]+), ip: ([0-9\\.\\- :,]+), refer: (.*), agent: (.*), body: ([\\[\\{].*[\\}\\]])'

1.3后端系统日志

后端系统日志是系统自己主动记录的，通常是前端或其他系统向后端系统请求接口数据，后端系统记录接口请求信息或接口返回结果信息。这种数据通常是系统间约定好的，因此是格式非常规范的日志数据，也可以直接使用Hive的正则技术处理数据。

例如：

格式一：（结果信息）

2018-07-03 06:50:00,142 [XNIO-2 task-28] INFO  com.leeyk99.bi.abt.rest.CoreApiController - 1A42F7C6_B904_A334_AB87_5A69A7034DA0  leeyk99PcRealClass 66 158

格式二：（接口信息）

2018-07-03 20:39:46,043 [XNIO-2 task-211] INFO  com.leeyk99.bi.abt.filter.LogFilter - GET  /api/v1/bi/abt?cid=973EA838_E20E_74E4_41AB_E218DA91D73E&uid=&site=mtw&terminal=leeyk99-M&lan=zh-tw took 1ms and returned 200

(1.2\1.3中的leeyk99是对源数据中某个公司品牌的替换)

关于Hive正则技术处理比较规范的日志数据，可以查看：（博客园）或者（印象笔记）

本篇学习使用Hadoop-MR清洗请求日志。

2.请求日志采集入库

对于日志文件的采集，我们数仓一般不会直接去生产系统去采集，而是由运维或者专门的小组负责日志采集，一般是采集落到HDFS或S3文件系统上或者某台接口机上，数仓采集入库这些文件，进行清洗加工。

ELK结构（Elasticsearch , Logstash, Kibana ）提供了一整套解决方案，并且都是开源软件，之间互相配合使用，完美衔接，高效的满足了很多场合的应用，这个结构是面向平台或系统用户的，用来查看监视日志，跟踪系统运行状况的。

Flume是Cloudera提供的一个高可用的，高可靠的，分布式的海量日志采集、聚合和传输的系统。

Flume+Kafka+Storm+mysql构建大数据实时系统

Flume+HDFS+KafKa+Strom实现实时推荐，反爬虫服务等服务

Flume+Hadoop+Hive的离线分析网站用户浏览行为路径

Flume+Logstash+Kafka+Spark Streaming进行实时日志处理分析

Flume+Spark + ELK数据系统实时监控平台

ftp文件传输也是一种非常重要的文件服务方式，但对于大量的日志可能不太适用。除非是日志离线归档收集好，再传输到接口机上供第三方取用。

关于实时收集等模式，暂无涉猎。

3.配置Maven-Hadoop环境

3.1.项目初始化


       
        com.leeyk99.udp
       
       
        hadoop-mapreduce
       
       
        1.0-SNAPSHOT

目标：创建一个Maven项目，配置Hadoop运行环境需要的Jar文件。

3.2.配置pom.xml

关于IDEA上Maven项目JAR文件自动下载配置，参考笔记

自动下载后，IDEA给该Maven项目下载了很多JAR文件（External Libraries下），除了我们自己配置的核心文件，还有相关必要的文件也被下载了，省去了我们逐个下载的麻烦。
