Snmp-based Enterprise Server Performance Monitoring System For The Design And Realization

The research and the development mainly is for examine the system face enterprise's performance supervisory system the performance condition,Improvement enterprise efficiency, promote efficiency , improve IT service level This has already become one of the bottlenecks of current enterprise's development gradually. This article revolves the author to participate in the development based on the SNMP enterprise server performance supervisory system design and the realization, to the development theory and the essential technology which involves have carried on the detailed analysis and the comparison Article elaboration main content including following several aspects:Through to network management agreement analysis, we use the SNMP agreement to take the system realization the technology base; Through to three kind of networks overhead constructions comparison, we use the distribution network system structure, and have absorbed the lamination as well as the central structure merit, fundamentally solves between the monitoring network transmission expenses as well as the monitoring ability contradiction Meanwhile in this foundatio, in detail discussed has used the performance supervisory system system structure which expanded based on SNMP This system structure divides the overall system the monitoring proxy, monitors the superintendent, the monitoring agreement as well as monitoring database these four partsThis article proposed the system performance monitoring function and the goal, all carried on in view of the present majority of applications has launched thediscussion, has made the unification in the communication agreement, the message format and the agreement data and so on have all made the standard, like this at your convenience in revision and expansion The article in the security aspect the supervisory system information security communication question conclusion will be two major parts: user identification and data encryption In order to solve these two kind of problems, the system uses in the data encryption aspect will use CBC-DE, wile in identification aspect we extend SNMP's VACM(View-based Access Control Model) and USM(user-based security model), and adds RBAC, and gives the expansion in the time response The article produced the service end host to control the procedure the overall structural design, from aspect and so on user contact surface, system disposition function, message control function controlled the procedure to the server end host the structure and the function has made the detailed analysis and the introduction...
