摘要
随着网络规模的扩大,日志审计系统中单个日志服务器受到处理能力的限制,已经成为系统的瓶颈。采用具备高可用性和负载均衡的日志服务器集群系统来解决这个问题,提出一个基于集群的日志审计系统。分析了该系统的体系结构、总体结构模型,以及各个组成模块的功能,并给出一个综合负载统计的动态负载均衡策略。最后,用排队论的方法来分析集群系统的性能。
With the expanding of network size, the transacting capability of the single log server in log audit system is limited, which has already become the bottleneck of that system. To address this problem, a log server cluster equipped with the features of high availability and load balancing, was introduced and a log audit system based on cluster was presented. The system architecture, the structure model of the system and the main modules were described, and a dynamic load balancing algorithm with synthetic loading statistic was provided. Finally, the performance of the log server cluster system was analyzed with the queue theory.
