# NetNMS
> NetNMS is a web-based network monitoring system for ISPs and IT companies: SNMP devices, Linux and Windows servers, OLT/ONU, NetFlow, BGP, maps and WhatsApp alerts.

One small binary to watch routers, switches, OLTs, ONUs and any SNMP device, including servers with SNMP enabled. Small or large network, with alerts on WhatsApp. NetNMS began with ISP networks. It works for any organisation that runs devices speaking SNMP, from a small office to a large network.
