Shell script that plots iPerf3's JSON file

This is a simple shell script that accepts the JSON output of iPerf3 and plots the results using gnuplot. Basically, there are two shell scripts:

This script converts iPerf3's JSON file to a Comma-separated value (CSV) file. It also uses AWK to format the fields.

This script accepts iPerf3's JSON file, calls preprocessor, and calls gnuplot to create PDF outputs for the following fields extracted from the JSON file:

• socket
• start
• end
• start
• seconds
• seconds
• bytes
• bits_per_second
• retransmits
• snd_cwnd
• rtt
• rttvar
• pmtu
• omitted

This script requires jq and gnuplot. Run the following command in the script's directory. It installs the dependencies, and makes the scripts accessible anywhere.

sudo make

preprocessor.sh <iperf_json_input> <output_directory>
Example: preprocessor.sh my_test.json simulation_results

plot_iperf.sh <iperf_json_file>
Example: plot_iperf.sh my_test.json

1. Launch mininet and create your topology
2. Launch the xterms of the hosts
3. Start the iPerf3 server:

iperf3 -s

4. Start the iPerf3 client: (-J to create a JSON output, -P to start multiple flows, -t to specify the transmission time, and finally, redirect the stdout to a file).

iperf3 -c 10.0.0.2 -J -P 4 -t 60 > my_test.json

5. Use the plot_iperf.sh script to generate the output. This will create a results directory containing the plots of all fields.

iperf_plot.sh my_test.json

Test the script on the my_test.json file provided in the sample directory
