티스토리 뷰

이 스크립트 하나만 있으면 오픈스택 배포를 위한 디렉터 노드부터 컨트롤러, 컴퓨트 노드의 하드웨어 상태를 점검하고, 서비스 상태까지 한꺼번에 점검을 할 수 있다. 물론 단점은 글씨로 나온다는 것이지만, 엔지니어가 퀵하게 오버클라우드 전 노드를 살펴보는용으로는 매우 훌륭하다고 생각한다. 게다가 로그도 남겨주니 1석 2조가 아닌가?

내용이 다소 길기는 하지만, 다음에 시간이 되면 중복되는 기능들을 함수로 변경하는 작업을 하면 좋을 것 같기는 하다. 그래도 이렇게 한번 스크립트를 짜 놓으면 모든 노드에 매번 들어가서 정보를 확인하지 않아도 되서 매우 편리하다.
