vROPS 설치 시, Express Installation이 아닌 일반 Installation을 선택하면 다음 화면과 같이 NTP 설정하는 단계가 확인됩니다.
## 아래 화면은 7.x 지만 8.x 에도 동일
이 단계에서 vROPS Node가 바라볼 NTP 서버 주소를 기입하면 되는데요.
최초 Node 구성 후에 추가로 구성하는 Node들은 자동으로 위 단계에서 설정한 NTP 서버를 바라보도록 추가 시에 설정됩니다.
이는 각 Node의 /etc/ntp.conf 파일에서 확인 가능합니다.
아래는 vROPS Master Node에 추가한 Remote Collector에서 확인한 /etc/ntp.conf 파일 결과입니다.
보시면 초기 설치 시점에 NTP로 지정했던 192.168.1.2 IP를 확인하실 수 있습니다.

현재 상태에서 NTP 정보는 Product UI와 Admin UI 양 쪽에서 모두 확인 가능합니다.
Product UI는 Administration > Cluster Management 로 이동한 후, Actions에서 Network Protocol Time Settings 메뉴를 선택하면 확인할 수 있습니다.
Admin UI에서는 우측 상단의 아래 빨간색으로 표시한 아이콘을 클릭하면 동일한 내용을 확인할 수 있습니다.
