Getting different metrics from mininet

[Mohamed Oualla]

Hello all, I am glad to be here with you

Please I need help, I want to ask if there is a way or a tool to make results of packets statistics from mininet into a csv file or a plot , for example getting the results of iperf test or http test and plot it to see metrics like delay, jitter or lost packets...?

Why do I need that? Because I want to show results of how packets are treated with and without an SDN controller. Please if I am wrong or have another suggestion let me know.

Thank you!

You may want to take mininet-dashboard:

https://github.com/sflow-rt/mininet-dashboard

The dashboard provides an up to the second view of traffic flowing over the Mininet topology. 

Unfortunately, the Mininet dataplane (OVS) doesn't include the instrumentation needed to support sFlow latency / queuing and dropped packet measurements:

https://sflow.org/sflow_drops.txt

Instrumentation to support these extensions is included in current generation switch ASICs.
