Network monitoring for ISPs and IT teams

NetNMS software to watch routers, switches, OLTs, ONUs and any SNMP device, including servers with SNMP enabled. Small or large network, with alerts on WhatsApp.

  • SNMP v2c / v3
  • OLT · ONU
  • NetFlow · BGP
  • WhatsApp
Live demo preview (simulated data)

Simulated example: two core routers connect three aggregation switches, which connect OLTs and ONUs. Link colours show utilisation. The demo plays a busy link, a link failure, a WhatsApp alert and a recovery.

Alerts

  1. Link recovered: ‎THANE-SW ↔ KALYAN-OLT‎
  2. WhatsApp alert sent to the NOC team

Why NetNMS

Monitoring that stays simple

Many monitoring setups mean installing and joining several components. NetNMS ships as one simple software and covers what ISP and IT teams watch every day.

NetNMS software

Go backend and React web UI in a single software. Runs on Linux and Windows. PostgreSQL stores configuration and events, and a built-in time-series database stores metrics.

Made for ISP networks

OLT and ONU status, optical power, BGP sessions, NetFlow and LLDP topology live in one web UI.

Alerts where your team is

WhatsApp, Telegram, e-mail and webhook notifications, with routing by severity, escalation and a delivery log.

  • 2Operating systems for the server

Who it is for

For ISPs and for IT teams

NetNMS began with ISP networks. It works for any organisation that runs devices speaking SNMP, from a small office to a large network.

Internet service providers

  • GPON and EPON OLT and ONU status with optical Rx/Tx power
  • BGP sessions and a NetFlow / BGP NOC view
  • LLDP topology maps with live link colours
  • Availability and 95th percentile traffic reports
ISP network monitoring

IT companies and enterprises

  • Routers, switches and any device that speaks SNMP v2c or v3
  • Linux and Windows servers with SNMP enabled, plus ICMP ping up/down
  • From a small office to a large multi-site network
  • Syslog and SNMP trap receivers in the same place
IT company monitoring

Live network map

See what is wrong, and where

Maps use live colours, so a failing link or a down device stands out at once. Click through to the port, the OLT or the ONU.

  • LLDP neighbours are discovered automatically and drawn as links between ports.
  • Link colours follow utilisation and status.
  • Sub-maps and a background image let you match your own sites.
  • Open any port to watch a live 1-second traffic graph.

How it works

Up and running in three steps

  1. We install it for you

    Our team installs NetNMS on your server, usually in about 10 minutes. You do not have to do anything.

  2. Add devices

    Create sites, import devices from CSV and add SNMP v2c or v3 credentials. Templates are matched automatically.

  3. Watch and get alerts

    Use dashboards, maps and reports. Alerts go to WhatsApp, Telegram, e-mail or webhook.

Where it runs

Light on hardware, flexible on where it runs

Run NetNMS on an Ubuntu server of your choice, in the cloud or on site, and reach remote networks over VPN.

  • Ubuntu Server recommended

    We recommend Ubuntu Server for the best results. Any Ubuntu version works. Windows is possible, but we do not prefer it.

  • Cloud or your own server

    Run NetNMS on a cloud server or on a server you own. Both work.

  • Remote networks over VPN

    Monitor remote or customer networks through a VPN or a tunnel, or from the customer end with a MikroTik or another VPN router.

  • Low CPU and RAM

    NetNMS needs little CPU and RAM, so it can monitor many devices even on modest hardware.

Coming soon

Which devices can it monitor?

Any device that speaks SNMP v2c or v3, plus ICMP ping up/down. Ready templates exist for Cisco, Huawei (including NE40E), Juniper EX, V-SOL and BDCOM OLTs, Grandstream and generic SNMP.

Can it monitor Linux and Windows servers?

Yes, when SNMP is enabled on the server. NetNMS reads what the server exposes over SNMP and checks it with ICMP ping.

Does it monitor OLTs and ONUs?

Yes. GPON and EPON OLT and ONU monitoring shows ONU status, serial and optical Rx/Tx power. Some devices do not expose optical power over SNMP.

How does it send alerts?

Through a WhatsApp gateway, Telegram, e-mail or webhook, routed by severity, with escalation, grouping and a delivery log.

What do I need to run it?

An Ubuntu Server is recommended, and any Ubuntu version works. Windows is possible, but we do not prefer it. NetNMS uses PostgreSQL for configuration and events and has its own built-in time-series database for metrics. It needs little CPU and RAM, and it can run on a cloud server too. We install it for you.
