摘　　要：在研究如何获取单个Linux集群服务器节点性能参数的基础上,利用CGI(Common Gateway Interface)技术,通过HTTP协议实现了异步采集Linux集群服务器节点性能参数的方法。在监控节点上利用QT编程实现Linux集群系统性能的实时监测及其可视化。通过定时器、CGI技术、HTTP协议、专用算法的有机结合,实现无序返回结果的有序化,达到实时、异步采集Linux集群服务器节点性能参数目的,是一种具有创新性的Linux集群系统性能实时监测方法。与传统的网络监测方法相比,具有占用系统资源少、可靠、实用的特点,可广泛应用于各种Linux集群系统,也为下一步实施Web服务器动态负载均衡打下基础。Based on study of single Linux cluster system node performance and its extraction methods,performance parameters of nodes are collected asynchronously by HTTP protocol and CGI（common gateway interface）technology.At last,the whole performance of Linux cluster system can be monitored on one node by coding on QT platform,which is a combination result of timer,CGI,HTTP protocol and special algorithm.It is a kind of innovational performance real-time monitoring method of Linux cluster system.It is proved that this solution is not only a reliable and practical monitor for different kinds of Linux cluster system,but also it is the basics of implementation of Web dynamic load balance based on Linux cluster system.
