基于TB+树云服务性能监控数据索引算法研究

云计算为充分发挥计算性能提供了解决方案，为了能更好支持云计算，对其进行监控成为了一个重要的问题。随着监控数据的增加，快速、准确地访问监控数据成为监控处理的约束。通过构建合适的索引，可以较好地改善大数据量查询的效率。本文给出了一个拥有大数据量的虚拟服务监控系统的存储模型，并给出了基于该模型之上的TB 树(Time B -Tree)二级索引模型。该索引提供了时间点和时间段的两种数据访问方式，经过实验验证，该索引方案获得了较好的访问性能。

Index Algorithm Research of Cloud Service Performance Monitoring Data Based on TB+ Tree

It will be an important problem to monitor the cloud computing for supporting it better, which provides the solution of computing performance adequately. As the increasing of the data, to access the monitoring data accurately and rapidly becomes a limit. It can be improved the efficiency of inquiries for massive data by creating suitable index. In the paper, a storage model was suggested for the large-scale data, and a Two_Layer Index called TB tree (Time B -Tree) which was based on the model is given. The time_piont and time_region access methods were provided on the index, and a good performance was proved by the experiment.
