NetFlow Traffic Analyser

Real-time network utilisation and bandwidth monitoring Contact us for a quote

SolarWinds® NetFlow Traffic Analyser (NTA) allows you to capture data from continuous streams of network traffic, and convert those raw numbers into easy-to-interpret charts and tables that quantify exactly how the corporate network is being used, by whom, and for what purpose.

With SolarWinds® NTA, it’s easier than ever to collect and analyse Cisco® NBAR2 and NetFlow, Juniper® J-Flow™, IPFIX, sFlow®, Huawei NetStream™, and other flow data.

Key Features

More Features


Bandwidth Threshold Alerting
Delivers an instant alert notification, including a list of top talkers when an interface exceeds its bandwidth utilisation threshold.

Bandwidth Usage by Application
Provides valuable insights into which applications are consuming the most network bandwidth, and tracks application traffic arriving from designated ports, source IPs, destination IPs, and even protocols.

Bandwidth Usage by IP Groups
Analyses network traffic with custom overlapping IP address groups. Create your own IP address groups to view network traffic the way that you want to see it.


Traffic Analysis Dashboard
Delivers a comprehensive, customisable view of your network traffic on a single pane of glass, allowing you to spot potential problems quickly with top ten views of network traffic data. Get to the root cause of bandwidth issues with an intuitive point-and-click interface.

Cross-stack Network Data Correlation
Accelerate identification of root cause by dragging-and-dropping network performance metrics on a common time line for immediate visual correlation across all of your network data.

Network Traffic Forensics
Enables you to drill down into any element’s traffic using multiple views to get the perspective you’re looking for. You can investigate and isolate excessive network bandwidth utilisation and unexpected application traffic.

CBQoS Performance Views
Enables you to view network traffic segmented by Class of Service methods, measure effectiveness of your CBQoS policies, and quantify bandwidth consumption by class map.

Border Gateway Protocol
Enables you to set up customised views of internet traffic for ISPs and organizations to better understand how traffic is balanced across providers.


Multi-Vendor Device Support

  • Analyzes NBAR2, NetFlow v5, NetFlow v9, sFlow v2, v4, v5, IPFIX, J-Flow, and Huawei NetStream data
  • Supports devices from Cisco, Extreme Networks, HP®, Juniper, Nortel Networks, Huawei, and other leading vendors
  • Supports NetFlow traffic from VMware® vSwitch

Flow-based Reporting
Enables you to create in-depth network traffic reports with a few clicks, or schedule automatic weekly delivery to your team.

Flow Navigator
Enables you to create and access personalized network traffic views by filtering NBAR2, NetFlow, J-Flow, sFlow, IPFIX, and Huawei NetStream data.

Top-Talker Optimisation
Determines which flows are representative of the majority of bandwidth usage. It stores those flows while disregarding flow data from users and applications that have a negligible impact on overall bandwidth. Boost overall performance of SolarWinds NTA up to 10x when capturing flows that represent 95% of the total network traffic.


Integrated Fault, Performance, and Configuration Management
Integrates with SolarWinds Network Performance Monitor (NPM), SolarWinds Network Configuration Manager (NCM), and SolarWinds User Device Tracker (UDT). This integration provides a unified solution for fault, performance, configuration management, automated device tracking, and switch port management.

Microsoft® Active Directory® Integration
Leverages your existing Active Directory user accounts to simplify login and account management.
