What is NetFlow collector?

NetFlow Collector: an application responsible for receiving flow record packets, ingesting the data from the flow records, pre-processing and storing flow record from one or more flow exporters.

Where can I collect NetFlow?

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 is NetFlow collected?

NetFlow records are traditionally exported using User Datagram Protocol (UDP) and collected using a NetFlow collector. The IP address of the NetFlow collector and the destination UDP port must be configured on the sending router. A single UDP packet loss can cause a huge impact on the statistics of some flows.

What is Ipfix collector?

IPFIX Collector: an application responsible for receiving flow record packets, ingesting the data from the flow records, pre-processing and storing flow record from one or more flow exporters.

How do I check my network flow?

Access your router by entering your router’s IP address into a web browser. Once you sign in, look for a Status section on the router (you might even have a Bandwidth or Network Monitor section depending on the type of router). From there, you should be able to see the IP addresses of devices connected to your network.

How do I record NetFlow data?
