hadoop 网站日志分析

时间:2015-10-08 12:49来源:linux.it.net.cn 作者:IT

一、项目要求

 

  • 本文讨论的日志处理方法中的日志，仅指Web日志。其实并没有精确的定义，可能包括但不限于各种前端Web服务器——apache、lighttpd、nginx、tomcat等产生的用户访问日志，以及各种Web应用程序自己输出的日志。  

 

二、需求分析： KPI指标设计

 PV(PageView): 页面访问量统计
 IP: 页面独立IP的访问量统计
 Time: 用户每小时PV的统计
 Source: 用户来源域名的统计
 Browser: 用户的访问设备统计

下面我着重分析浏览器统计



 

三、分析过程

1、 日志的一条nginx记录内容

222.68.172.190  - - [18/Sep/2013:06:49:57 +0000] "GET /images/my.jpg HTTP/1.1" 200 19939 
"http://www.angularjs.cn/A00n" 
"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.66 Safari/537.36"

2、对上面的日志记录进行分析

remote_addr : 记录客户端的ip地址, 222.68.172.190
remote_user :  记录客户端用户名称, –
time_local:  记录访问时间与时区, [18/Sep/2013:06:49:57 +0000]
request: 记录请求的url与http协议, “GET /images/my.jpg HTTP/1.1″
status:  记录请求状态,成功是200, 200
body_bytes_sent:  记录发送给客户端文件主体内容大小, 19939
http_referer:  用来记录从那个页面链接访问过来的, “http://www.angularjs.cn/A00n”
http_user_agent:  记录客户浏览器的相关信息, “Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.66 Safari/537.36″  

3、java语言分析上面一条日志记录（使用空格切分）

String line = "222.68.172.190 - - [18/Sep/2013:06:49:57 +0000] \"GET /images/my.jpg HTTP/1.1\" 200 19939 \"http://www.angularjs.cn/A00n\" \"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.66 Safari/537.36\"";
        String[] elementList = line.split(" ");
        for(int i=0;i<elementList.length;i++){
            System.out.println(i+" : "+elementList[i]);
        }

测试结果：

6、算法模型: 并行算法 

Browser: 用户的访问设备统计
– Map: {key:$http_user_agent,value:1}
– Reduce: {key:$http_user_agent,value:求和(sum)}

8 R制作图片

 

data<-read.table(file="borwer.txt",header=FALSE,sep=",") 

 names(data)<-c("borwer","num")

 qplot(borwer,num,data=data,geom="bar")

 

 

 

解决问题

1、排除爬虫和程序点击，对抗作弊

解决办法：页面做个检测鼠标是否动。

2、浏览量 怎么排除图片

3、浏览量排除假点击？

4、哪一个搜索引擎访问的？

5、点击哪一个关键字访问的？

6、从哪一个地方访问的？

7、使用哪一个浏览器访问的？
