Design And Implementation Of Remote Host Monitor System Based On SSH

With the rapid growth of Internet users in China, the IT enterprise server is also an ever-growing the server security relationship to the lifeblood of the company. A lot of problems is irregular, unpredictable, systems engineer impossible24hours to refresh pages,24hours on the server, it is impossible24hours a ping server status. Therefore, the remote host server implementation monitoring is necessary.Common faults for the server, such as the service can not log in, slow response, users can not write data, high CPU load, disk usage is too high, the remote host monitoring solution based on log analysis. The program can monitor the real-time operating status of the remote host’s CPU, memory, hard disk, Web servers, database software and other services, an exception occurs, immediately notify the responsible officer.In this paper, SSH development of technology, knowledge-based software engineering theory, based on the business needs of the remote host monitoring, developed to achieve. Firstly, this paper analyzes the background of the remote host monitoring proposed to introduce remote monitoring and system development related technologies used, and presents the main research ideas and research methods. Then, the remote host monitoring system functional requirements are analyzed, shows a flow chart of each module and a brief description; and gives the overall system design, interface design, and database design. Finally, the development of technology in the SSH remote host monitoring implementation, key module gives the core code and description; development is completed, the system is a unit testing and related performance tests.The remote host monitoring system, not only has configurable, versatility, portability and scalability characteristics of high, but also can improve network management personnel to fault location speed and response time, has great practical value and realistic significance.
