网络应用软件监控系统管理信息存储优化设计

对SNMP中MIB信息和协议数据单元扩充的基础上,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。论文详细介绍了其管理信息存储的优化设计过程。包括三种存储设计方案及其优缺点的比较、内存映射文件的存储数据结构设计、插入类节点、变量节点和删除节点等数据管理算法、数据刷新算法等。通过内存映射文件方式存储管理信息,高效地完成了收集各应用程序实例的监控信息任务并实现了监控信息的存储、共享和监控模块与管理代理间实时信息交换的功能。

Optimization Storage Design of Management Information in Net Monitoring System for Application Software

On the basis of expansion of management information base and protocol data unit,a net monitoring system for application software has been designed and implemented.The monitoring system plays a monitoring role for the member variable and function of the class in the applying procedure.This paper introduces in detail optimization storage design of management information,including three design schemes of storing management information,advantages and disadvantages of them,storage structure design of file mapping,managing data algorithm consisting of insertion of class node,variable node and node deletion,as well as updating data algorithm,etc.By means of this storage method,on the one hand,the task of collecting management information from the applying procedure is accomplished efficiently.On the other hand,monitoring module has function of management information of storing,sharing,and exchanging for management agent timely.
