What is a NetFlow analyzer?
What is a NetFlow analyzer?
A NetFlow analyzer is a tool deployed to perform monitoring, troubleshooting and in-depth inspection, interpretation, and synthesis of traffic flow data. Analyzing NetFlow facilitates more accurate capacity planning and ensures that resources are used appropriately in support of organizational goals.
What is NetFlow Collector software?
A NetFlow collector is part of a flow monitoring system designed to receive, process, and store IP traffic data packets from these network devices. Once the data has been properly formatted, NetFlow collectors forward the data to another application for analysis.
Is Traffic Analyzer a networking device?
A network traffic analyzer is designed to capture or log traffic as it flows across the network. At a glance this helps with the following: Identify what applications/protocols are running on the network. Identify bandwidth hogs down to a user, application or device level.
What is network traffic analyzer?
Network traffic analysis (NTA) is a method of monitoring network availability and activity to identify anomalies, including security and operational issues. Common use cases for NTA include: Collecting a real-time and historical record of what’s happening on your network. Detecting malware such as ransomware activity.
How does NetFlow collect data?
How to Collect NetFlow Data
- Flow exporter: a network device (a router or firewall) in charge of obtaining flow data and exports it to a flow collector.
- Flow collector: a device that collects the exported flow data.
- Flow analyzer: an application that examines and analyses the flow data collected by the flow collector.
How do I add a router to NetFlow Analyzer?
How to add a device in NetFlow Analyzer?
- Navigate to Settings > Discovery > Export Flow.
- Enter the device Hostname / IP Address.
- Select respective SNMP credential or Add new SNMP credential (if credential does not exist)
- Provide the below information to communicate to the device in sequence.

What is NetFlow Traffic Analyzer (NTA)?
SolarWinds ® NetFlow Traffic Analyzer (NTA) provides unmatched network analysis to let you know what’s using bandwidth. NTA can also run as a module in SolarWinds Network Performance Monitor (NPM). It’s well worth trying out both solutions, called Network Bandwidth Analyzer Pack, because these two tools are amazing together.
What is NetFlow and how does NetFlow work?
Routers with NetFlow tools enabled create NetFlow reports, which are then processed and exported to a NetFlow collector. The NetFlow collector processes and compresses the data; the analyzer performs the necessary traffic analysis, and then breaks the analysis down into an easily digestible format.
What are the best open source tools for monitoring NetFlow?
Another NetFlow monitoring open source tool, ntopng is a traffic analysis solution that captures packets to monitor flow data. To get the data, it relies on an open-source NetFlow collector called nProbe. The web-based interface consolidates packet data into flows. Then you can sort flows according to criteria like IP address, protocol, and
