Scaling Up ntopng Flow and Packet Processing
As traffic rate increases, it is important to tune packet processing in order to avoid drops and thus educe visibility. This post will show you a few tricks for improving the overall performance and better exploit modern multicore systems. The Problem ntopng packet processing performance depends on the number of ingress pps (packets per second) as well the number of flows/hosts being monitored and number of enabled behavioural checks. With ntopng you can expect to process (your mileage varies according to the CPU/system you are using) a few (< 5) …
