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: https://www.cnblogs.com/leeyuki/p/9548811.html (博客园)或者 ABT日志入库记录 (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
<groupId>com.leeyk99.udp</groupId>
<artifactId>hadoop-mapreduce</artifactId>

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
配置Hadoop运行需要的JAR文件

关于IDEA上Maven项目JAR文件自动下载配置,参考笔记 Maven
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。
