  • Loadrunner监控Tomcat

    2010-07-01 18:00:27

     

    Lo转adRunenr没有监控Tomcat的专用监控器，为了用lr达到监控tomcat的目的可以通过打开Tomcat自带的Status页面之后，利用lr的关联技术得到相关的数据，把数据输出到lr自定义的监控器中。

    　　1、打开Tomcat的status页面，方法为编辑Tomcat的conf目录下的tomcat-users.xml文件，在文件中添加

    <tomcat-users>
      <role rolename="manager"/>
      <user username="admin" password="pass" roles="manager"/>
    </tomcat-users>

     

    修改配置并重启服务后：

    访问：http://192.168.146.228/manager/status

    输入用户名密码，即可以看到相应信息；　

    　2、开发lr脚本

    vuser_init()

    {

     double atof(const char *string); //一定要记得声明函数，否则得到的数据都是错误的；

       //保存JVM内存数值
        web_reg_save_param("JVM_FreeMemory",
                           "LB=Free memory: ",
                           "RB= MB",
                           "Ord=1",
                           LAST);

        web_reg_save_param("JVM_TotalMemory",
                           "LB=Total memory: ",
                           "RB= MB",
                           "Ord=1",
                           LAST);

        web_reg_save_param("JVM_MaxMemory",
                           "LB=Max memory: ",
                           "RB= MB",
                           "Ord=1",
                           LAST);


        //保存http-80连接数值
        web_reg_save_param("http_MaxThreads",
                           "LB=Max threads: ",
                           "RB= ",
                           "Ord=1",
                           LAST);

        web_reg_save_param("http_CurrentThreadCount",
                           "LB=Current thread count: ",
                           "RB= ",

                           LAST);

        web_reg_save_param("http_CurrentThreadBusy",
                           "LB=Current thread busy: ",
                           "RB= ",

                           LAST);

        web_reg_save_param("http_MaxProcessingTime",
                           "LB=Max processing time: ",
                           "RB= ms",
                           "Ord=1",
                           LAST);

        web_reg_save_param("http_ProcessingTime",
                           "LB=Processing time: ",
                           "RB= s",
                           "Ord=1",
                           LAST);

        web_reg_save_param("http_RequestCount",
                           "LB=Request count: ",
                           "RB= ",
                           "Ord=1",
                           LAST);

        web_reg_save_param("http_ErrorCount",
                           "LB=Error count: ",
                           "RB= ",
                           "Ord=1",
                           LAST);

        web_reg_save_param("http_BytesReceived",
                           "LB=Bytes received: ",
                           "RB= MB",
                           "Ord=1",
                           LAST);

        web_reg_save_param("http_BytesSent",
                           "LB=Bytes sent: ",
                           "RB= MB",
                           "Ord=1",
                           LAST);

      //定义tomcat内存使用情况的监视器事务； 

     lr_start_transaction("status");

     web_set_user("admin", "123456","192.168.146.146:80");


     web_url("status",
      "URL=http://192.168.146.146/manager/status",
      "Resource=0",
      "RecContentType=text/html",
      "Referer=",
      "Snapshot=t1.inf",
      "Mode=HTML",
      LAST);

     lr_end_transaction("status", LR_AUTO);

    //使用lr_user_data_point（）添加数据到图表中去

        lr_user_data_point("Tomcat JVM FreeMemory", atof(lr_eval_string("{JVM_FreeMemory}")));

        lr_user_data_point("Tomcat JVM TotalMemory", atof(lr_eval_string("{JVM_TotalMemory}")));
