Action()
{
       

        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);

                                           "LB=Max memory: ",
                                           "RB= MB",

                                           LAST);

        web_set_user("admin","123456","127.0.0.1:8080");

        web_url("status",
                        "URL=http://127.0.0.1:8080/manager/status",
                        "Resource=0",
                        "RecContentType=text/html",
                        "Referer=",
                        "Snapshot=t1.inf",

                        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}")));

        return 0;
}
