A Windows service installed on your SolarWinds server (or a dedicated Additional Polling Engine). It listens on standard ports (UDP 2055, 6343, 4739, etc.). The collector ingests millions of flow records per minute, aggregates them, and stores them in the SolarWinds database. solarwinds netflow traffic analyzer
Routers, switches, and firewalls (Cisco, Juniper, Fortinet, Arista, etc.) generate flow records. Each record contains key fields: Source/Destination IP, Port, Protocol, Type of Service (ToS), and bytes/packets. | Feature | SolarWinds NTA | PRTG NetFlow
This article provides a comprehensive deep dive into SolarWinds NTA—its architecture, key features, deployment strategies, and how it separates itself from standard bandwidth monitors. At its core, SolarWinds NTA is a traffic analysis and bandwidth monitoring tool that leverages flow protocols exported from network devices. Unlike Simple Network Management Protocol (SNMP), which tells you how much data moved through an interface (utilization), NTA tells you who (IP address), what (application/protocol), and where (conversation pairs). At its core, SolarWinds NTA is a traffic
