网络应用软件监控系统管理代理的设计与实现

对简单网络管理协议中管理信息库和协议数据单元进行扩充，采用面向对象的技术，设计并实现了面向应用软件的网络监控系统．该系统提供了对应用程序类中成员变量和成员函数的监控功能．研究了管理代理的功能模块设计、内存文件映射与同步机制应用、报文分组算法与差错控制机制等．管理代理作为系统的通信中心，一方面，完成收集各应用程序实例的监控信息任务．另一方面，具有发送受控站点的管理信息以及转发管理站点的控制信息功能．从而实现了管理代理与监控模块及管理站点间监控信息实时、准确的交换．

Design and Implementation of Management Agent in Net Monitoring System for Application Software

Based on an expansion of the management information base and protocol data unit of simple network management protocol, a net monitoring system for application software was designed and implemented by adopting object-oriented technology. The monitoring system offers a monitoring function for the member variable and function of the class in the applying procedure. Then a careful study was made of the functional design of management agent, of its application of file mapping and synchronism mechanism, and of its algorithm design of datagram grouping and technology of error control. As the center of communication, management agent accomplishes collecting information of applying procedures and on the other hand, it plays a role in transmitting control command or management information. Therefore, the exact and timely exchange for information can be attained from monitor module to management agent and to management station.
