Abstract
Centri za nadzor telefonije pri operaterjih in manjša podjetja, ki so posredniki telefonskega prometa, uporabljajo sisteme za spremljanje klicev v realnem času. Pozornost namenjajo kakovosti storitve, ki v veliki meri zavzema nadzor nad kakovostjo večjih vzorcev klicev po različnih omrežjih končnih operaterjev. Cilj diplomskega dela je bil implementirati izboljšavo za nadzor kakovosti VoIP telefonije, ki bi omogočala grafično predstavitev kazalnikov kakovosti klicev. Podani so rezultati raziskave obstoječih orodij na trgu ter definirane zahteve sistema. V diplomski nalogi je predstavljena rešitev z implementacijo sklada ELK za urejanje, statistično obdelavo in grafično predstavitev kazalnikov kakovosti klicev. Pri ovrednotenju rešitve je nakazana možnost nadgradnje s pošiljanjem filtriranih podatkov iz orodja Logstash preko izhoda neposredno na Zabbix strežnik. Podane so ugotovitve, ki izhajajo iz vnaprej postavljenih zahtev sistema.

Title:Monitoring of quality indicators in VoIP
Abstract:
Control centres of telephony operators and other smaller companies that route telephone traffic have a system of regularly monitoring calls in real time. Dedicating a lot of attention to the quality of service, mostly monitoring and controlling quality of larger patterns of calls going to different destinations. The aim of the thesis was to implement improvements in the field of controlling quality of VoIP telephony, enabling visual representations of formal quality indicators of calls such as ASR, NER, ACD. Research was made of the existing tools on the market at the moment and summarized the requirements of the system. The thesis presents a solution of implementing ELK stack for editing data, making statistical analysis and visualization of quality indicators of calls. While evaluating this solution an upgrade is suggested for using Zabbix output of data filtered in Logstash to send them directly to Zabbix server. Findings are given resulting from pre-established system requirements.

Keywords:VoIP, quality parameters, elastic stack, Docker, JSON.
