<![CDATA[This study addresses the critical need for proactive network management in MSMEs, where reliance on stable connectivity is high but existing monitoring tools are often costly or reactive. We propose a low-cost, proactive monitoring framework that integrates the open-source Zabbix platform with ICMP Ping detection and real-time Telegram Bot notifications. Developed using the Network Development Life Cycle (NDLC) methodology, the system’s novelty lies in its practical integration of instant messaging to achieve near real-time fault notification in a scalable environment. Implemented at an ISP (CV Media Computindo) managing over 250 active clients, the framework was evaluated using 61 client devices on a virtualized Ubuntu Server. Experimental results demonstrate high operational impact: failure notifications were delivered in under two seconds with a 100% success rate, significantly reducing average device downtime from 30 minutes to just 3 minutes. Despite minor limitations regarding polling intervals and external messaging dependencies, the system proved highly effective and cost-efficient. This research provides a scalable foundation for resource-constrained organizations to enhance network reliability through open-source tools and offers a benchmark for future comparative studies with enterprise platforms like PRTG, Nagios, and Prometheus.]]>
