Design And Implementation Of Email Server Monitoring Systyem

At present, email has replaced traditional mail and played a very important role in the field of the whole life. However, various mail transceiver errors brought many problems. Because of all sorts of questions, many important mails cannot reach users' hands and brought huge losses to users. In many cases, a fault of mail server occurs,but the user doesn't know, this sort of loss will be greater. In view of this situation, we developed the monitoring system.The advantages of this system are very obvious. First of all, the monitoring system excluded the situation that mail problems have happened but users didn't know, because the monitoring system is timely monitoring, timely alarm. Secondly, the monitoring system has auto-detection function, so give a lot of troubleshootings to save time, when the system fails, user is difficult to get the cause of the error immediately according to the phenomenon, such a procedure for automatic detection is more effective than that user detects the error step by step. In addition, the alarm works in two ways in circulation, this situation ensures users get error informations from many channels, and also saved time for trouble-shooting.The function of this system is ensuring E-mail server functions are normal by constantly monitoring. This process includes monitoring, detection and alarm.First of all,the monitoring.We are monitoring by sending a simulation mail timly, the monitoring period and the business class are choosed when users registerd. If monitoring has discoverd a error, alarm to monitoring system and users at the first time, and start-up the detection function. Second,the detection.it has PING and DNS for testing the user server, eventually the system got the generate diagnosis reports by the detection result,and sent to user to grate errors.In addition, this system also has the funtions of working of user's data including thickening removing checking and instant status query. Users can query history data of different periods anytime because of the storage of vast amount of historical data, and also, the data generation line chart would display the image of the different periods of server status. Of course, these data are available to of the same server in different periods and the state contrast of different servers in the same period, and it can improve the function of server functions with the state.My main job. First,analyzed the email server's composition and working principle, through principle analysis and organization of fine ground analyzed data, the potential failure E-mail server, this system's necessity and the objective demand will naturally come out; On the demand sexual analysis, functional requirements is the most important part, detailed analysis of the system's main function, in non-functional analysis, also gives the system characteristics and optimal hot link; Then the main structure gives the system of system function, let everybody have a clear understanding of realization, first give function module level figure, is actually the main function of work flowchart. In module design are given before the first among various modules such contact figure. The following content is well designed to function modules, each module is a class figure said. The fourth part, several important module implementation flow chart, the algorithm and some important function display.
