Network flow monitoring is great for helping you understand how a network is performing. Network flow offers up-to-the-minute information about communications occurring over the network, including who is sending how much data to whom, as well as how and when. Flow data is available from common devices like routers, switches, firewalls, and load balancers and it is easily collected enterprise wide, including the cloud, by a centralized flow analysis and reporting solution. Thus, network flow provides an excellent perspective for end-to-end performance monitoring and incident detection and response.
