오픈스택 기반 클라우드 컴퓨팅 시스템의 모니터링에 관한 연구

Abstract

Cloud computing systems are an ever-growing field, and OpenStack is one of the open source platforms can provide IaaS that the third largest cloud computing service in market. Because IaaS is a key goal of providing virtual machines to cloud service consumers, the ability of cloud service providers to monitor the health of resource pools such as compute, storage and networks is critical. However, ceilometer, an OpenStack existing metric collection project, is not enough to monitor the status of the resource pools because it collects metrics centrally on virtual machines. Therefore, this paper analyzes the existing monitoring system and proposes a monitoring system architecture that adds a metric collection agent to monitor the resource pools. In addition, it is proposed a way to express collected metrics to make it easier to grasp the status of the resource pool at a glance.
