如何设置监控目标服务器cpu，内存等信息

[wanxi3]

我把ngrinder-monitor拷贝到了目标服务器，sh run_monitor_bg.sh后，创建测试用例，添加了目标服务器的IP。但是测试完成后，还是没有目标服务器的信息，是我哪里没有做对么

Did you check the firewall b/w controller and target?

You can try to see it's connectable from controller by using

> # in your controller sever, run following.
> telnet {your_target_ip} 13243

执行时，加上-o参数，指定配置文件为本目录下的配置文件__agent.conf, 并将monitor.binding_port设置为你的controller端的ip;

如需搜集自定义数据，可以查看如下文章：

ngrinder服务器IP：192.168.84.140
目标服务器IP：192.168.84.174

将monitor.binding_port修改成192.168.84.140

[root@localhost ngrinder-monitor]# cat __agent.conf
common.start_mode=monitor
# If you want to monitor bind to the different local ip not automatically selected ip. Specify below field.
#monitor.binding_port=hostname_or_ip
monitor.binding_port=192.168.84.140

运行./run_monitor.sh -o 报错：

关于配置文件的疑问：
1、monitor.binding_port 这个难道不应该是端口吗？我一开始写成：13243，如果是Controller的IP 我觉得应该是：monitor.binding_host

[熊金飞]

各位好，问题已经解决，是配置文件说明有误：

cat /root/.ngrinder_agent/agent.conf
common.start_mode=monitor
# If you want to monitor bind to the different local ip not automatically selected ip. Specify below field.
monitor.binding_ip=192.168.84.174
monitor.binding_port=13243

这里monitor.binding_port=hostname_or_ip修正为：monitor.binding_ip=hostname_or_ip

备注:看了ngrinder的源码ngrinder/ngrinder-core/src/main/java/org/ngrinder/common/constants/MonitorConstants.java:，描述如下：

public interface MonitorConstants {
        public static final String PROP_MONITOR_BINDING_IP = "monitor.binding_ip";
        public static final String PROP_MONITOR_BINDING_PORT = "monitor.binding_port";

        /**
         * Monitor Constant
         */
        public static final int DEFAULT_MONITOR_COLLECTOR_INTERVAL = 1;
        public static final String DEFAULT_MONITOR_DOMAIN = "org.ngrinder.monitor";
        public static final String SYSTEM = "name=System";
        public static final String MONITOR_FILE_PREFIX = "monitor_system_";
}


但是模板配置文件：ngrinder/ngrinder-controller/src/main/resources/ngrinder_agent_home_template/agent_monitor.conf
写的有误：
common.start_mode=monitor
# If you want to monitor bind to the different local ip not automatically selected ip. Specify below field.
#monitor.binding_port=hostname_or_ip
monitor.binding_port=${monitorPort}

Thanks. We fixed this issue by https://github.com/naver/ngrinder/pull/179
