摘要
云平台监控系统是有效保障云服务质量的重要环节,本文在Openstack云平台上进行相应的虚拟服务器监控系统设计.系统结合Openstack的开源性和强大的可扩展性的特点,以Openstack中的网络组件Neutron面对庞大虚拟服务器流量转发时所出现的瓶颈问题为出发点,结合SDN软件定义网络技术及其重要的南向接口协议OpenFlow解决流量瓶颈问题,设计基于Libvirt和sFlow协议的监控系统,负责获取虚拟机群数据流量信息,并且向上层控制模块以及用户反馈最新的平台负载情况,使用控制模块和流表控制流量转发,最终使整个系统平台达到负载均衡.
Cloud platform monitoring system is an important segment to effectively guarantee the quality of cloud services. In this study, the corresponding virtual server monitoring system is designed on the Openstack cloud platform.The system combines the characteristics of Openstack＇s open source and strong scalability. At the same time, it starts with the bottleneck problem which appears when Neutron, the network component in Openstack faces the huge virtual server traffic forwarding. This study combines SDN technology and openflow, its important southward interface protocol, to solve the traffic bottleneck problem. At the same time, it designs the monitoring system based on Libvirt and sFlow protocol responsible for obtaining data flow of virtual cluster, giving feedbacks of the latest platform load to the upper control module and user, and using control module and flow table to control traffic forwarding. Finally, the whole system platform can achieve load balancing.
