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!
