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
1 <tomcat-users> 2 <role rolename="manager"/> 3 <user username="admin" password="admin" roles="manager"/> 4 </tomcat-users>
2、LR脚本开发
1 lr_start_transaction("monitor tomcat"); 2 web_reg_save_param("JVMFreeMemory", 3 "LB=Free memory: ", 4 "RB= MB", 5 "Ord=1", 6 LAST); 7 web_reg_save_param("JVMTotalMemory", 8 "LB=Total memory: ", 9 "RB= MB", 10 "Ord=1", 11 LAST); 12 13 web_reg_save_param("JVMMaxMemory", 14 "LB=Max memory: ", 15 "RB= MB", 16 "Ord=1", 17 LAST); 18 19 web_url("status", 20 "URL=http://{ServerName}/manager/status", 21 "Resource=0", 22 "RecContentType=text/html", 23 "Referer=", 24 "Snapshot=t1.inf", 25 "Mode=HTTP", 26 LAST); 27 28 lr_end_transaction("monitor tomcat", LR_AUTO); 29 30 // Tomcat JVM metrics 31 lr_user_data_point("Tomcat JVM Free memory", atof(lr_eval_string("{JVMFreeMemory}"))); 32 lr_user_data_point("Tomcat JVM Total memory", atof(lr_eval_string("{JVMTotalMemory}"))); 33 lr_user_data_point("Tomcat JVM Max memory", atof(lr_eval_string("{JVMMaxMemory}")));
搞定！
