Analiza delovanja računalniških omrežij s programskim orodjem CACTI : diplomsko delo

Gazvoda, Silvo (author), Mraz, Miha (mentor), Moškon, Miha (comentor)

V diplomski nalogi smo opredelili tehnike in pristope, ki jih najpogosteje srečamo pri izvajanju nadzora in upravljanja omrežij. Izbira tehnike, s katero se lotimo nadzora omrežja, zavisi od kompleksnosti nadzorovalnih metrik in vzpostavljene infrastrukture. Pri nadzoru zmogljivosti smo spoznali arhitekturo, v kateri centralizirani upravljavec pošilja poizvedbe upravljanim napravam. Naprave svoje zmogljivostne parametre izpostavijo v objekte definirane znotraj baze upravljavskih informacij. Vrednosti parametrov se med upravljavcem in napravami najpogosteje prenašajo v podatkovnih enotah protokola SNMP (angl. Simple Network Management Protocol). Nadaljevali smo z analizo programskega orodja Cacti. Orodje omogoča opazovanje različnih metrik zmogljivosti omrežnih virov skozi množico grafov. V zadnjem delu smo se lotili vzpostavitve sistema za nadzor omrežja v katerem smo opazovali lokalne in oddaljene naprave. Orodje Cacti se je izkazalo kot prilagodljivo orodje za nadzor omrežij.

• Title: Computer networks analysis with Cacti

Abstract

In this thesis, we have identified techniques and approaches that are most commonly encountered in network management systems. We have described availability and performance monitoring techniques. Selection of monitoring technique depends on the complexity of monitored parameters and preliminary established architecture. Network monitoring suggests architecture in which centralized manager collects and analyses data from managed devices. Managed devices expose their network statistics through objects defined within the Management Information Base. Simple Network Management Protocol allowing the manager to communicate with the managed hosts. Afterwards we analyse network monitoring and graphing tool Cacti. Cacti allows a manager to poll managed devices and graph the gathered data. In the last part we cover the details of establishing network management system in which we monitor local and remote network resources. Cacti has emerged as adaptable tool for monitoring computer networks.
