What Is Netflow

NetFlow is an open but proprietary network protocol developed by Cisco Systems to run on Cisco IOS-enabled equipment for collecting IP traffic information.

Cisco routers that have the Netflow feature enabled generate netflow records; these are exported from the router in User Datagram Protocol (UDP) or Stream Control Transmission Protocol (SCTP) packets and collected using a netflow collector.

High level analysis of network traffic
View top level utilization information with Scrutinizer and see the amount of traffic being generated through specific interfaces of a router.

Information without limitations
Scrutinizer can accept multiple flows, there are no limitations on the number of flows that can be received; however, the Vital Signs should be monitored to make sure the hardware can handle the amount of data it is receiving.
