  8. EMS란 무엇인가? Event Monitoring Service • Event Monitoring Services는 다음과 같은 내용을 제공하는 하나의 구조체 입니다.: • 자원 감시 설정을 위한 일반적인 툴 제공 • 특정 자원에서 event또는 critical value 발생시 여러 경로를 통해 통보 • 표준 API를 통해 새로운 resource monitor를 쉽게 적용 가능 Configuration Clients Notification Methods Configuration Core/ Framework Target Apps EMS Monitors Resources

  9. HW Event Monitoring 구성 요소 Event Monitoring Service • EMS • Event 통보를 위한 구조체 • Monitoring request manager ( monconfig) • Hardware Monitors • 환경설정 files 및 툴 • Support Tools Manager • Event를 기록 및 보여주는데 사용되는 low-level error handling components. • STM 은 하나의 Map을 제공하는데, 이는 감시해야 될 장치와 그것을 결정하는 HW monitors 에 의해 사용된다.
