Abstract: In an open and dynamic network environment，the distributed software system shows characteristics of large scale，loose aggregation，complicated behavior and so on.In order to monitor the interactive behavior effectively，the object of interactive behavior monitoring is analyzed.The design principle of interactive behavior monitoring mechanism is presented and based on which the three-tier architecture of monitoring framework is designed，and the implementation of interactive behavior monitoring mechanism is realized.The monitoring mechanism is applied in the distributed e-commerce application system，and the results show that the monitoring mechanism is effective.

Key words: interactive behavior monitoring, distributed software, trustworthy, component interaction

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，为有效监测其交互行为，分析了交互行为监测对象，明确了对交互行为中哪些可信相关数据进行监测；给出了交互行为监测机制的设计原则，遵循此原则设计了3层结构的监测框架；并在此基础上实现了交互行为监测机制。该监测机制已应用于分布式电子商务应用系统中，结果表明该监测机制是有效的。
