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

 double atof(const char*string);    //把字符串转换成浮点数

 Action()
 {
     float freememory,totalmemory,maxmemory;    //定义指标变量

     web_set_user("tomcat",
         lr_decrypt("5bc7f31441549b071635"),
         "127.0.0.1:8080");    //设置登录tomcat的用户名和密码

     web_reg_save_param("Free memory",
         "LB=Free memory:",
         "RB=Total memory:",
         LAST);    //设定监控参数  空闲内存 这里使用的关联函数

     web_reg_save_param("Total memory",
         "LB=Total memory:",
         "RB=Max memory:",
         LAST);    //总共内存

     web_reg_save_param("Max memory",
         "LB=Max memory:",
         "RB=",
         LAST);    //最大内存

     web_url("web_url",
         "URL=http://127.0.0.1:8080/manager/status",
         "TargetFrame=",
         "Resource=0",
         "Referer=",
         LAST);    //访问tomcat的status页面

     sleep();

     //把获取的字符类型转化为浮点数
     freememory=atof(lr_eval_string("{Free memory}"));
     totalmemory=atof(lr_eval_string("{Total memory}"));
     maxmemory=atof(lr_eval_string("{Max memory}"));

     //自定义数据点，输出各个监控参数
     lr_user_data_point("Tomcat JVM Free memory",freememory);
     lr_user_data_point("Tomcat JVM Total memory",totalmemory);
     lr_user_data_point("Tomcat JVM Max memory",maxmemory);

     sleep();

     return ;
 }
