Modularni strežnik syslog z vhodnim filtrom : diplomsko delo

Markelj, Matej (author), Marolt, Matija (mentor)

Spremljanje omrežnih naprav se tradicionalno opira na ICMP, SNMP in syslog. Slednji je s stališča enostavnosti in razumljivosti prava izbira, v kolikor v spremljanju sodeluje večje število računalnikarjev, ki niso nujno omrežni strokovnjaki. V tem diplomskem delu so prestavljeni protokoli za spremljanje omrežnih naprav, njihove prednosti in slabosti ter primeri uporabe. Poleg tega je predstavljen tudi razvoj, testiranje in implementacija modularnega strežnika syslog. Razviti so bili štirje moduli, ki sporočila shranjujejo na strežnik SQL in v tekstovno datoteko, ali pa jih posredujejo prek e-pošte in kratkih tekstovnih sporočil. Ključni del sistema je vhodni filter, ki, glede na nastavitve, prepušča oziroma zavrača prihajajoča sporočila. Rešitev je bila razvita z namenom, da porabi malo resursov, testirana pa je bila na velikem številu ter različnih omrežnih napravah.

• Title: A modular syslog server with input filter

Abstract

Network device monitoring traditionally depends on ICMP, SNMP and syslog. The latter is, due to its simplicity, used in environments where network devices are monitored by IT personnel that do not necessarily work in networking field. In this thesis, network monitoring protocols have been assessed in detail, and typical usage explained. Also, development, testing and implementation of a modular syslog server is presented. Four modules have been developed to save messages to SQL server or text file, or to forward them using e-mail or SMS. Key component of this system is the input filter which lets only relevant messages through. The solution was designed to consume little resources and has been tested on a large number and different types of network devices.
