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.

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
Enter . Designed as an add-on to the legendary SolarWinds Network Performance Monitor (NPM) or as a standalone module, NTA transforms raw flow data (NetFlow, sFlow, J-Flow, IPFIX) into actionable intelligence. Designed as an add-on to the legendary SolarWinds
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.
In the modern digital ecosystem, the network is the silent circulatory system of every organization. While it’s relatively simple to know if a link is up or down (thanks to standard uptime monitors), the real challenge lies in answering the harder questions: Who is using all the bandwidth? What application is causing latency? Where is that mysterious traffic spike coming from at 3:00 AM?
