해결 방안
The persistent hostname list used in syslog-ng is written into the /opt/syslog-ng/etc/hosts file, which functions similarly to the /etc/hosts file. This file is for syslog-ng's use.
The DNS is case insensitive, therefore from a technical perspective, uppercase hostnames have minimal added value.
It's recommended to use lowercase hostnames in the persistent hostname list to avoid validation errors.
