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

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！
