A helpdesk ticket reports “the network is slow.” Using SolarWinds NetFlow Analyzer, an engineer identifies that a single IP address is streaming 4K video during business hours. The engineer applies a QoS policy or notifies the user.
| Feature | Description | |---------|-------------| | | Real-time and historical traffic graphs per interface, application, or conversation. | | Application Visibility | Identifies top applications (e.g., YouTube, Office 365, Dropbox) consuming bandwidth. | | CBQoS Analysis | Monitors Class-Based Quality of Service policies to verify traffic shaping effectiveness. | | Security Forensics | Detects DDoS attacks, botnet activity, or data exfiltration by spotting abnormal flow patterns. | | Custom Alerting | Triggers alerts based on thresholds (e.g., sudden spike in traffic to a geographic region). | | Capacity Planning | Generates trend reports to forecast when interfaces will reach saturation. | netflow analyzer solarwinds
Leveraging SolarWinds NetFlow Analyzer for Network Traffic Visibility and Performance Optimization A helpdesk ticket reports “the network is slow
In modern network environments, understanding bandwidth consumption and traffic patterns is critical for maintaining performance and security. SolarWinds NetFlow Analyzer is a prominent tool designed to collect, analyze, and report on flow data (NetFlow, sFlow, J-Flow, IPFIX). This paper examines the architecture, key features, and practical applications of SolarWinds NetFlow Analyzer. It discusses how the tool enables network administrators to identify bandwidth bottlenecks, detect anomalous traffic, enforce QoS policies, and conduct capacity planning. The paper also explores integration with SolarWinds Orion Platform and compares the solution to alternative flow analysis tools. 1.

A sudden surge in outbound traffic to an unfamiliar external IP address triggers an alert. Flow analysis shows an internal host encrypting and uploading large files. The security team isolates the host and investigates.
