Designand Implementation Of The View Layer Of A Monitoring System For Domestic System Software

With the continuous development of computer network technology, the Web application is one of the domestic research hot spot. At the same time of satisfying the informationization work and life, People also hope the Web applications to achieve more complex business logic and higher friendly interaction experience demand. In this topic, the enterprise users need to grasp the running situation of the domestic system software of anytime and anywhere. Based on this requirement, we develope a resource monitoring system.The whole system used B/S architecture which including the presentation layer and the business layer of two parts. Based on the system structure,we took the modular development and realized the monitoring system by calling the module interface. When we developed the system, I was responsible for monitoring results display function which was also need to use RIA technology to achieve.The RIA technology mainly includes Flex and Ajax. In the early stage of the system development,we used Flex technology which can realize the function systems show layer. Flex technology includes the using of the MXML page interface language to structures view layer, using the WebService component to call the background data interface for monitoring data, using AcitonScript language to complete data processing package business logic and so on.By hanging the data in the chart to Flex components,we display the result to the user. Later with the deepening understanding of the system view layer, we used Ajax technology as a follow-up study of paper work. We used HTML+CSS technology to build page and the j Query framework to complete Ajax requests. Through the Python language, we developed the application as a middle bridge to call the back-end data interface and return the background data processing. Finally,we encapsulated into a json data format to the front and then mounted the monitoring data to HighCharts chart component.Practice shows that through the Flex and Ajax technology we successfully achieve the display the function of monitoring results. In real-time monitoring, as time goes on we can show the real-time running status of the monitoring server; At the end of the monitoring, we can also show all the historical monitoring data from the beginning to the end.
