Nfdump displays the traffic among network devices and thereby allows seeing how much bandwidth is consumed by the single flows. This may be a useful information, but indeed, it is not very meaningful. Since Nfdump just lists the single flows between two ports (including the generated traffic), it is difficult to understand at a glance:
- To which service a flow belongs
- How many flows (and traffic) a certain service generates
Nfdump just allows to display the traffic among network devices and thereby, seeing how much bandwidth is consumed by the single flows.
Actually, we want to know, which service generated most traffic during a certain period. To get this information, we have to associate the single flows to a certain service. How can we do this? – Based on the network ports we can identify, which flows belong to which service. Summarizing all flows, which belong to one service, we can see at a glance, how much bandwidth was consumed by the single services.
Traffic generated by different services
We integrated a new functionality to the NetEye Reporting to visualize the generated traffic by the different IT service.
