网络应用软件监控系统中监控模块的设计与实现

Design and Implementation of Monitor Module inNet Monitor System for Application Softwares

在对SNMP中MIB信息和协议数据单元扩充的基础上,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。介绍了其监控模块的功能设计、工作逻辑设计、应用程序中变量的获取技术和监控信息的存储以及共享技术。监控模块是整个监控系统中最基础、最核心的单元,是提供给软件开发人员使用的一个通用接口模块,为此,在监控模块内部封装了与外界进行通信和对本地监控信息进行管理的内部实现模块,并向软件开发人员提供了一系列接口来操作该模块。将监控模块集成到应用程序中后,通过该模块,使得这个监控系统对应用程序类中成员变量和成员函数具有监控功能。

On the basis of expansion of management information base and protocol data unit, a net monitor system for application softwares based on object-oriented technology was designed and implemented. This paper introduces in detail the functional design, logical design for working, technology of gaining variables among the applying procedure, as well as the storing and sharing of monitored message in the monitoring module. Monitoring module is the basic and core unit for the whole monitoring system, an common module enveloped internal reality of communication with the external world, and the management for the native monitoring message. Moreover, it provides software explorers with a series of interfaces for operating the model. After monitoring module is integrated in the applying procedure, monitoring system plays a monitoring role for the member variable and its function of the class in the applying procedure.
