Study on Real Time Monitoring of Linux Cluster System Performance and Its Visualization

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.
