LoadRunner监控Tomcat

一、配置被监控的Tomcat

需要在tomcat的conf目录下tomcat-users.xml文件中，配置管理员角色
<tomcat-users>
  <role rolename="manager"/>
  <user username="test" password="test" roles="manager"/>
</tomcat-users>

 二、LR单协议选择WEB(HTTP/TCP)-->将Action部分替换为如下内容：

double atof (const char *string);//此函数在使用前必须先声明

Action()
{
  web_set_user("test", //tomcat用户名
  "test", //tomcat密码
  "192.168.16.107:9090");
 
       lr_start_transaction("monitor tomcat");

       web_reg_save_param("JVMFreeMemory",
              "LB=Free memory: ",
              "RB= MB",
              "Ord=1",
              LAST);
 
       web_reg_save_param("JVMTotalMemory",
              "LB=Total memory: ",
              "RB= MB",
              "Ord=1",
              LAST);
 
       web_reg_save_param("JVMMaxMemory",
              "LB=Max memory: ",
              "RB= MB",
              "Ord=1",
              LAST);
 
       web_reg_save_param("HTTPMaxThreads",
              "LB=Max threads: ",
              "RB= ",
              "Ord=1",
              LAST);
 
       web_reg_save_param("HTTPCurrentThreadCount",
              "LB=Current thread count: ",
              "RB= ",
              "Ord=1",
              LAST);
 
       web_reg_save_param("HTTPCurrentThreadBusy",
              "LB=Current thread busy: ",
              "RB=<br>",
              "Ord=1",
              LAST);
 
       web_reg_save_param("JKMaxThreads",
              "LB=Max threads: ",
              "RB= ",
              "Ord=2",
              LAST);
 
       web_reg_save_param("JKCurrentThreadCount",
              "LB=Current thread count: ",
              "RB= ",
              "Ord=2",
              LAST);
 
       web_reg_save_param("JKCurrentThreadBusy",
              "LB=Current thread busy: ",
              "RB=<br>",
              "Ord=2",
              LAST);

        web_url("status",
  "URL=http://192.168.16.107:9090/manager/status",
  "TargetFrame=",
  "Resource=0",
  "RecContentType=text/html",
  "Referer=http://192.168.16.107:9090",
  "Snapshot=t5.inf",
  "Mode=HTML",
  LAST);
 
       lr_end_transaction("monitor tomcat", LR_AUTO);
 
       // Tomcat JVM metrics
       lr_user_data_point("Tomcat JVM Free memory（当前可用的内存）", atof(lr_eval_string("{JVMFreeMemory}")));
       lr_user_data_point("Tomcat JVM Total memory(当前已经分配的Tomcat JVM内存)", atof(lr_eval_string("{JVMTotalMemory}")));
       lr_user_data_point("Tomcat JVM Max memory(当前允许分配的最大Tomcat JVM内存)", atof(lr_eval_string("{JVMMaxMemory}")));

    /*通过计算得到jvm内存使用率*/
    lr_user_data_point("Tomcat JVM memory %used（内存使用率）", (atof(lr_eval_string("{JVMTotalMemory}"))-atof(lr_eval_string("{JVMFreeMemory}")))/atof(lr_eval_string("{JVMTotalMemory}"))*100);
 
     
       // Tomcat web server metrics
       lr_user_data_point("Tomcat HTTP Max threads（最大线程数）", atof(lr_eval_string("{HTTPMaxThreads}")));
       lr_user_data_point("Tomcat HTTP Current thread count", atof(lr_eval_string("{HTTPCurrentThreadCount}")));
       lr_user_data_point("Tomcat HTTP Current thread busy", atof(lr_eval_string("{HTTPCurrentThreadBusy}")));

    
       // Tomcat servlet container metrics
       lr_user_data_point("Tomcat JK Max threads", atof(lr_eval_string("{JKMaxThreads}")));
       lr_user_data_point("Tomcat JK Current thread count ", atof(lr_eval_string("{JKCurrentThreadCount}")));
       lr_user_data_point("Tomcat JK Current thread busy", atof(lr_eval_string("{JKCurrentThreadBusy}")));

 return 0;
