Watch the access network
Monitor OLTs and ONUs, optical Rx/Tx power and SFP health, so weak or offline links are easy to find.
NetNMS is a network monitoring system built for ISP private networks. It watches routers, switches, OLTs and ONUs, shows BGP and NetFlow views, draws topology maps with live colours and sends alerts to WhatsApp, Telegram, e-mail or webhook. It is one small binary for Linux or Windows.
Know your core and edge
Check BGP session state and flaps, see top talkers with NetFlow and watch CPU, memory, temperature, fans and power modules on core routers.
Alert the NOC where they are
Send alerts to WhatsApp, Telegram, e-mail or webhook, with maps and reports per site for the whole team.
