The differences between one form and the other are concentrated in the methodology used. In both techniques, of course, the goal is the same: to obtain information on network traffic that can be presented in an interface that facilitates its evaluation. There are at least two ways to perform network traffic analysis: packet analysis and network traffic flow analysis. This natural first impulse to observe traffic is actually justified, as traffic analysis has proven useful in identifying problems such as configuration errors, server performance deterioration, latency problems in some of the network components, and so many other error conditions. It is easy to understand that when faced with, for example, an application performance problem, we want to be able to observe and evaluate the traffic generated, and this is just what network traffic analysis does. Both fields provide ways to obtain data that allows us to obtain information about the general state of the platform. Monitoring has always relied on both network administration and network traffic analysis.
