LoadRunenr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= ",
                       "Ord=1",
                       LAST);

    web_reg_save_param("http_CurrentThreadBusy",
                       "LB=Current thread busy: ",
                       "RB= ",
                       "Ord=1",
                       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}")));

    lr_user_data_point("Tomcat JVM MaxMemory", atof(lr_eval_string("{JVM_MaxMemory}")));

    lr_user_data_point("Tomcat http MaxThreads", atof(lr_eval_string("{http_MaxThreads}")));

    lr_user_data_point("Tomcat http CurrentThreadCount", atof(lr_eval_string("{http_CurrentThreadCount}")));

    lr_user_data_point("Tomcat http CurrentThreadBusy", atof(lr_eval_string("{http_CurrentThreadBusy}")));

    lr_user_data_point("Tomcat http MaxProcessingTime", atof(lr_eval_string("{http_MaxProcessingTime}")));

    lr_user_data_point("Tomcat http ProcessingTime", atof(lr_eval_string("{http_ProcessingTime}")));

    lr_user_data_point("Tomcat http RequestCount", atof(lr_eval_string("{http_RequestCount}")));

    lr_user_data_point("Tomcat http ErrorCount", atof(lr_eval_string("{http_ErrorCount}")));

    lr_user_data_point("Tomcat http BytesReceived", atof(lr_eval_string("{http_BytesReceived}")));

    lr_user_data_point("Tomcat http BytesSent", atof(lr_eval_string("{http_BytesSent}")));

return 0;

}

上述需要哪些值，可以根据实际需求来取舍！

我试了一下监控tomcat http_8080，数据好像是不正确的！请问是什么问题？double atof(const char *strin.


如果使用的端口是8080
web_set_user("admin", "123456","192.168.146.146:80");
"URL=http://192.168.146.146/manager/status",
这些URL相关的都要增加对应的8080端口

为什么我的tomcat的conf目录下的tomcat-users.xml中原先设置好的<tomcat-users>
  <role rolename="manager"/>
  <user username="admin" password="pass" roles="manager"/>
</tomcat-users>总是会消失！很郁闷！
