Design And Implementation Of Cluster Monitoring On Information Security Audit System

With the information security audit system is running on-line in each Province of State Grid Corporation, it has impact on the efficiency of operating that the amount of operation is gradually increased and server overload operation often appeared. The audit system is made into server cluster, which greatly improves the load capacity of the system, and also enhances system robustness and reliability. Due to the large number of nodes and their components in the cluster, in order to improve system resource utilization and availability, and enhance the overall performance of the system. Administrator need to get some real-time information from each node in server cluster, like memory usage, CPU usage, the details of each service. Therefore, it is necessary to design a cluster monitoring system of information security audit system.This paper designs and implements a cluster management and monitor system based on information security audit system. The system is divided into four layers, which are cluster monitoring layer, data storage layer, cluster management layer and graphical user interface layer. The system adopts the B/S model, based on linux virtual server cluster system. This paper will introduce the system requirement analysis, design principles and system design, and introduce the design and implementation of all layers of system in detail. In addition, this paper creatively proposes health diagnosis model based server nodes, to assess the robustness of the whole system, and detect the problems of system in time. Users can get access to the system with Web interface, and there is no need of any complex command input to monitor and control the cluster system. Experiments are conducted to test the function and performance of the system, and show that the system can monitor and control the audit system cluster well, also it has a good user experience and a high reliability.
