Monitoramento contínuo de redes - desenvolvimento de uma solução automatizada com Zabbix

Abstract

This work presents the development of a complete solution for continuous network monitoring using the Zabbix platform integrated with Grafana, applied to the operational environment of Internet Service Providers. The aim is to replace reactive diagnostic practices — based on manual checks, disconnected tools, and late fault detection — with an automated system capable of collecting real-time metrics, generating advanced visualizations, and accelerating technical decision-making. To achieve this, requirement elicitation was conducted with the network operations team, followed by analysis of current processes, mapping of the infrastructure architecture, and identification of the main performance and availability indicators. Based on this analysis, customized dashboards were specified, configured, and validated in Zabbix, complemented by dynamic Grafana panels that enhance graphical visualization and support historical analyses. The solution includes monitoring of BGP stability, optical power levels, link utilization, PPPoE sessions, CGNAT pool usage, and VLAN distribution, in addition to automated alerts delivered via Telegram. The results demonstrate that the Zabbix–Grafana integration eliminates reliance on manual checks, increases diagnostic accuracy, reduces Mean Time to Repair, and improves the predictability and operational stability of the network. The proposed system promotes greater efficiency in infrastructure management and can be easily adapted to different ISP environments, highlighting its potential for scalability, automation, and strategic support to service continuity.
