hadoop日志分析

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。事实上并没有精确的定义，可能包含但不限于各种前端Webserver——apache、lighttpd、nginx、tomcat等产生的用户訪问日志，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): 页面訪问量统计
 IP: 页面独立IP的訪问量统计
 Time: 用户每小时PV的统计
 Source: 用户来源域名的统计
 Browser: 用户的訪问设备统计

以下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client的ip地址, 222.68.172.190
remote_user :  记录clientusername称, –
time_local:  记录訪问时间与时区, [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client文件主体内容大小, 19939
http_referer:  用来记录从那个页面链接訪问过来的, “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）

1 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\"";
2         String[] elementList = line.split(" ");
3         for(int i=0;i<elementList.length;i++){
4             System.out.println(i+" : "+elementList[i]);
5         }

測试结果：

01 0 : 222.68.172.190
02 1 : -
03 2 : -
04 3 : [18/Sep/2013:06:49:57
05 4 : +0000]
06 5 : "GET
07 6 : /images/my.jpg
08 7 : HTTP/1.1"
09 8 : 200
10 9 : 19939
11 10 : "http://www.angularjs.cn/A00n"
12 11 : "Mozilla/5.0
13 12 : (Windows
14 13 : NT
15 14 : 6.1)
16 15 : AppleWebKit/537.36
17 16 : (KHTML,
18 17 : like
19 18 : Gecko)
20 19 : Chrome/29.0.1547.66
21 20 : Safari/537.36"

4、实体Kpi类的代码：

01 public class Kpi {
02     private String remote_addr;// 记录client的ip地址
03     private String remote_user;// 记录clientusername称,忽略属性"-"
04     private String time_local;// 记录訪问时间与时区
05     private String request;// 记录请求的url与http协议
06     private String status;// 记录请求状态；成功是200
07     private String body_bytes_sent;// 记录发送给client文件主体内容大小
08     private String http_referer;// 用来记录从那个页面链接訪问过来的
09     private String http_user_agent;// 记录客户浏览器的相关信息
10     private String method;//请求方法 get post
11     private String http_version; //http版本号
12
13     public String getMethod() {
14         return method;
15     }
16     public void setMethod(String method) {
17         this.method = method;
18     }
19     public String getHttp_version() {
20         return http_version;
21     }
22     public void setHttp_version(String http_version) {
23         this.http_version = http_version;
24     }
25     public String getRemote_addr() {
26         return remote_addr;
27     }
28     public void setRemote_addr(String remote_addr) {
29         this.remote_addr = remote_addr;
30     }
31     public String getRemote_user() {
32         return remote_user;
33     }
34     public void setRemote_user(String remote_user) {
35         this.remote_user = remote_user;
36     }
37     public String getTime_local() {
38         return time_local;
39     }
40     public void setTime_local(String time_local) {
41         this.time_local = time_local;
42     }
43     public String getRequest() {
44         return request;
45     }
46     public void setRequest(String request) {
47         this.request = request;
48     }
49     public String getStatus() {
50         return status;
51     }
52     public void setStatus(String status) {
53         this.status = status;
54     }
55     public String getBody_bytes_sent() {
56         return body_bytes_sent;
57     }
58     public void setBody_bytes_sent(String body_bytes_sent) {
59         this.body_bytes_sent = body_bytes_sent;
60     }
61     public String getHttp_referer() {
62         return http_referer;
63     }
64     public void setHttp_referer(String http_referer) {
65         this.http_referer = http_referer;
66     }
67     public String getHttp_user_agent() {
68         return http_user_agent;
69     }
70     public void setHttp_user_agent(String http_user_agent) {
71         this.http_user_agent = http_user_agent;
72     }
73     @Override
74     public String toString() {
75         return "Kpi [remote_addr=" + remote_addr + ", remote_user="
76                 + remote_user + ", time_local=" + time_local + ", request="
77                 + request + ", status=" + status + ", body_bytes_sent="
78                 + body_bytes_sent + ", http_referer=" + http_referer
79                 + ", http_user_agent=" + http_user_agent + ", method=" + method
80                 + ", http_version=" + http_version + "]";
81     }
82
83
84
85 }

5、kpi的工具类

01 package org.aaa.kpi;
02
03 public class KpiUtil {
04     /***
05      * line记录转化成kpi对象
06      * @param line 日志的一条记录
07      * @author tianbx
08      * */
09     public static Kpi transformLineKpi(String line){
10         String[] elementList = line.split(" ");
11         Kpi kpi = new Kpi();
12         kpi.setRemote_addr(elementList[0]);
13         kpi.setRemote_user(elementList[1]);
14         kpi.setTime_local(elementList[3].substring(1));
15         kpi.setMethod(elementList[5].substring(1));
16         kpi.setRequest(elementList[6]);
17         kpi.setHttp_version(elementList[7]);
18         kpi.setStatus(elementList[8]);
19         kpi.setBody_bytes_sent(elementList[9]);
20         kpi.setHttp_referer(elementList[10]);
21         kpi.setHttp_user_agent(elementList[11] + " " + elementList[12]);
22         return kpi;
23     }
24 }

6、算法模型: 并行算法 

Browser: 用户的訪问设备统计
– 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")

解决这个问题

1、排除爬虫和程序点击，对抗作弊

解决的方法：页面做个检測鼠标是否动。

2、浏览量 怎么排除图片

3、浏览量排除假点击？

4、哪一个搜索引擎訪问的？

5、点击哪一个keyword訪问的？

6、从哪一个地方訪问的？

7、使用哪一个浏览器訪问的？
