Network and Server Performance Monitoring Using LibreNMS, Telegram, and UniFi Controller

Universities heavily depend on information technology to support their academic activities. Universitas Muhammadiyah Semarang (Unimus) currently operates with a total bandwidth of 1.3 Gbps. The primary issue is the current monitoring system's inability to provide comprehensive resource usage information or real-time notifications during network disruptions. This leads to an average network repair time exceeding three days. This research aims to enhance network management effectiveness at Unimus by utilizing the Network Development Life Cycle (NDLC) method. Implementing this method provides accurate bandwidth and resource usage information for routers and servers. The findings demonstrate that the average uptime of network devices and servers reached 99% within one day, with peak bandwidth usage of 944 Mbps. Real-time notifications significantly reduced the network repair time to one day, enhancing network maintenance effectiveness by 66.6%. Beta testing results indicated that 69% of respondents strongly agreed, and 31% agreed that the monitoring system simplifies network management. Implementing the UniFi Controller and upgraded access points improved the campus wireless network quality. Test results showed wireless network users achieving speeds of 10 Mbps. Quality of Service (QoS) tests yielding a throughput of 1276 kbps, 0% packet loss, and 4.8 ms jitter, indicating optimal internet access performance.
