性能测试工具LoadRunner30-LR之监控Tomcat
步骤:
1.通过LR去访问tomcat监控页(安装tomcat的过程可以百度一下)
2.然后通过关联取监控数据
3.通过lr_user_data_point()添加数据到图表中去
1 double atof(const char*string); //把字符串转换成浮点数
2
3 Action()
4 {
5 float freememory,totalmemory,maxmemory; //定义指标变量
6
7 web_set_user("tomcat",
8 lr_decrypt("5bc7f31441549b071635"),
9 "127.0.0.1:8080"); //设置登录tomcat的用户名和密码
10
11 web_reg_save_param("Free memory",
12 "LB=Free memory:",
13 "RB=Total memory:",
14 LAST); //设定监控参数 空闲内存 这里使用的关联函数
15
16
17 web_reg_save_param("Total memory",
18 "LB=Total memory:",
19 "RB=Max memory:",
20 LAST); //总共内存
21
22
23 web_reg_save_param("Max memory",
24 "LB=Max memory:",
25 "RB=",
26 LAST); //最大内存
27
28
29 web_url("web_url",
30 "URL=http://127.0.0.1:8080/manager/status",
31 "TargetFrame=",
32 "Resource=0",
33 "Referer=",
34 LAST); //访问tomcat的status页面
35
36 sleep(5);
37
38 //把获取的字符类型转化为浮点数
39 freememory=atof(lr_eval_string("{Free memory}"));
40 totalmemory=atof(lr_eval_string("{Total memory}"));
41 maxmemory=atof(lr_eval_string("{Max memory}"));
42
43 //自定义数据点,输出各个监控参数
44 lr_user_data_point("Tomcat JVM Free memory",freememory);
45 lr_user_data_point("Tomcat JVM Total memory",totalmemory);
46 lr_user_data_point("Tomcat JVM Max memory",maxmemory);
47
48 sleep(5);

51 return 0;
