监控tomcat 首先要在tomcat的conf下的 tomcat-users.xml中增加user

代码：

Action_Tomcat(){
        double atof(const char * string);    web_set_user("tomcat","tomcat","localhost:8080");    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);    web_reg_save_param("HTTP_MaxThreads",                      "LB=Max threads: ",                      "RB= ",                      "Ord=1",                      LAST);    web_reg_save_param("HTTP_MaxProcessingTime",                      "LB=Max 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_BytesReceived",                      "LB=Bytes received: ",                      "RB= MB",                      "Ord=1",                      LAST);    lr_think_time(5);    web_url("status",            "URL=http://localhost:8080/manager/status",            "TargetFrame=",            "Resource=0",            "Referer=",            "Snapshot=t1.inf",            "Mode=HTML",            LAST);    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_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_BytesReceived",atof(lr_eval_string("{HTTP_BytesReceived}")));    return 0;}

脚本完成，单击运行，然后···

检查了一下发现

这俩Action不一致，修改后运行脚本，ok了。

监控Tomcat的这段脚本代码放在新插入一个Action里面，并且放在之前录制来的业务脚本后面

然后就可以从Controller中观察到tomcat的运行状态了。

值得一提的是只有应用lr_user_data_point()函数，“User Defined Data Points”才处于可用状态。
