It seems http://${INFLUX_SERVER}:8086 can not be connected. I'd suggest to check the connection manually. And firewalld might be blocking the requests.

感谢您的回复，上述问题已经解决，原因是esmon_config中的server：reinstall为false，改为true即可安装成功。

安装成功后登陆grafana界面，查看了lustre的statistis发现有些指标的数据采集失败。查看mds的节点

不知道是哪里的配置有误，请指教，期待您的回复，谢谢

I noticed the following errors:

Please check your Lustre version is compatible with es3 (2.10). Otherwise, the data wo't be collected properly. If 2.10 is not the closest version with your Lustre version, please change the Lustre version in /etc/esmon_install.conf.

我安装的lustre是2.12，esmon为esmon-1.3.ge627284.x86_64.iso。

尝试一：将/etc/esmon_install.conf配置文件中的lustre version修改为es4仍然存在数据收集失败的消息：
