Hi, If you want all open source, there are a couple of options: Cacti + weathermap - native-ish integration Librenms + weathermap - This one doesn't have netflow/sflow but is based on interface's bandwidth (SNMP) Nfdump + weathermap - you would have to integrate it yourselves and probably use something like ELK stack for dashboards.

Para: 'NANOG list' <nanog@nanog.org> Asunto: sFlow/NetFlow Weathermap     Hi,     We're looking for suggestion for a "cost effective" sFlow/NetFlow solution with dynamic Weathermap for a MAN.     As the usual most open source solution got grabbed by corporation and put behind paywall without much development.     ntopng seems to be a good candidate we might try it with a site but with when your basic interconnect are 40Gb... that ain't gonna fly.     Thanks. -- ----- Alain Hebert ahebert@pubnix.net PubNIX Inc. 50 boul.
