![]() NetFlow exporter: When a client request is sent to a server, the device operating as an exporter tool reads the data packet headers and creates a flow record containing data about the IP addresses and ports the data is traveling to and from, the protocol number, and the size of the data and number of packets.NetFlow monitoring solutions are made up of three primary tools: an exporter, a collector, and an analysis application: Released as a feature on Cisco routers, NetFlow allows you to monitor IP network traffic information as data packets enter or exit an interface. NetFlow solutions are a commonly used standard for monitoring network flow data. Many NetFlow monitoring solutions also include reporting functions with at-a-glance understanding of current and historical network issues. Knowing the root cause of a network flow problem is a necessary first step to resolving the issue. Troubleshooting issues: If you experience a network slowdown or sudden changes in traffic, NetFlow data can be useful in determining exactly what devices or processes are causing the bottleneck. ![]() ![]() Security: NetFlow tools can be used to spotlight anomalies in baseline network behavior, providing admins with forensic evidence and tools to examine cybersecurity events in detail.NetFlow analysis can help identify under-provisioned resource pools and provide clear evidence of what needs to be prioritized as the company grows. Scaling: If network utilization increases without the proper resources and tools to support it, insufficient bandwidth will create chokepoints in network traffic.Quality of service: NetFlow data can help admins ensure sufficient bandwidth is allocated for all service agreement levels. ![]()
