Netflow v9 Datagram Knowledge Series: Part 7 - SolarWinds NetFlow Traffic Analyzer

Level 12

Welcome to SolarWinds NetFlow v9 Datagram Knowledge Series.  This is a 7 part series of blogs to provide the IT professional a basic understanding of how flow technology works, specifically Cisco’s NetFlow v9, what metrics are being captured, and how they are interpreted to help you perform comprehensive network traffic monitoring.

Today's topic is an overview of SolarWinds NetFlow Traffic Analyzer.

SolarWinds NetFlow Analyzer (NTA) monitors network traffic by capturing flow data from network devices, including Cisco® NetFlow v5 or v9, Juniper® J-Flow, IPFIX, sFlow®, and Huawei NetStream™, and identifies which users, applications, and protocols are consuming the most bandwidth and highlights the IP addresses of the top talkers.

SolarWinds NTA is an effective network traffic monitoring software that helps you capture Cisco NetFlow (v5 or v9) data from continuous streams of network traffic passing through NetFlow-enabled network devices and convert the raw metrics of the Export Packet into easy-to-interpret charts and tables that quantify exactly how, by whom, and for what purpose the corporate network is being used.
