LoadRunner 实现监控Tomcat

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="admin" roles="manager"/>
</tomcat-users>

2、LR脚本开发

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_url("status", 
        "URL=http://{ServerName}/manager/status", 
        "Resource=0", 
        "RecContentType=text/html", 
        "Referer=", 
        "Snapshot=t1.inf", 
        "Mode=HTTP", 
    LAST);
 
   lr_end_transaction("monitor tomcat", LR_AUTO);
 
// Tomcat JVM metrics
  lr_user_data_point("Tomcat JVM Free memory", atof(lr_eval_string("{JVMFreeMemory}")));
  lr_user_data_point("Tomcat JVM Total memory", atof(lr_eval_string("{JVMTotalMemory}")));
   lr_user_data_point("Tomcat JVM Max memory", atof(lr_eval_string("{JVMMaxMemory}")));
