Answer “the internet is slow” with evidence
Find the IPs, applications and ports eating your bandwidth within seconds of a bottleneck.
NetFlow, sFlow, IPFIX
Flow records exported by your routers, switches and firewalls are stored by an nfdump-based collector on the Netronus appliance. Explore top talkers, applications, protocols, countries and subnets live or over any time range; subnets that exceed their thresholds and suspicious traffic are flagged automatically.
