A CONCEPT FOR CENTRALIZED COMPUTER NETWORK MONITORING WITH SNMP

Vse več organizacij in podjetij je odvisnih od svojih računalniških omrežij, posel pa je zelo odvisen od statusa le-teh. Če podjetjem, ki so zelo odvisna od računalniškega omrežja, le-to izpade samo za nekaj minut, lahko izgubijo veliko denarja in tudi ugled ter zaupanje strank. Ko je pomembna vsaka sekunda delovanja računalniškega omrežja, ga moramo neprekinjeno nadzorovati. Najbolj učinkovit način za to je, da uporabimo avtomatizirana orodja za nadzor in upravljanje. V diplomskem delu bomo izpostavili problem nadzora in upravljanja centraliziranega računalniškega omrežja in opisali osnovni koncept nadzorovanja. Predstavili bomo tudi osnovna orodja za nadzor in upravljanje, SNMP-protokol, njegovo vlogo in namen uporabe. Izdelali bomo programsko opremo za analizo SNMP-paketov, skozi katero bomo predstavili strukturo in delovanje SNMP-protokola.More and more organizations depend on their computer networks. If a network dependent businesses go down for even a few minutes, they can loose a lot of money in sales and customer\u27s confidence. When every second of network time counts the system must be monitored continuously. The most cost effective way to do this is to use an automated network management tool. In this thesis we will raise the issue of centralized control and management of computer networks and describe the basic concept of it. We will present the basic tools for monitoring and management, SNMP-protocol, the role and purpose of it. We will implement the software for analyzing SNMP-packets, through which we will present the structure and operation of the SNMP-protocol
