摘  要:在开放动态的网络环境中,分布式软件呈现出规模庞大、松散聚合、行为复杂等特点,需要对其进行动态监测。提出了一种由策略驱动的监测模型,该模型由适应性策略选择AOP切面,监测模型的监测器由这些切面组成。利用动态织入机制,在目标系统运行过程中,随着监测值的变化,适应性策略动态地增加或删除监测器。因此,监测模型能自适应程序和当前系统的变化,动态调整监测强度,以使监测负载保持均衡,从而取得最佳监测效果,达到动态监测的目的。模拟实验结果表明,所设计的监测模型是合理的。In an open and dynamic network environment,distributed software shows the characteristics of large-scale,loose aggregation and complex behavior,which needs dynamically monitor.Proposes a strategy-driven monitoring model in which AOP(Aspect Oriented Programming) aspects are selected by adaptive strategy.With dynamic weaving mechanisms,the monitor composed by the aspects can be added and deleted according to the change of monitor value in the running process of target system.Therefore the model is able to adapt procedures and current system conditions changing and dynamically adjust the monitoring intensity to keep a balance of monitoring load,so as to get best monitoring results and achieve dynamic monitoring purposes.Simulation results show that the design of the monitoring model is reasonable.
