Quick script to get the statistics of traffic on Tor Project's Snowflake proxy instance running locally on docker

snowstats.sh

#!/bin/bash --posix

docker logs snowflake-proxy 2>&1 | grep --color=auto 'Traffic Relayed' | awk '
{
    # Extract the download and upload values
    down[1] = $14
    down[2] = $15
    gsub(/[^a-zA-Z]/, "", down[2])
    up[1] = $17
    up[2] = $18
    gsub(/[^a-zA-Z]/, "", up[2])

    # Convert to bytes
    if (down[2] == "B") down_total += down[1];
    else if (down[2] == "KB") down_total += down[1] * 1024;
    else if (down[2] == "MB") down_total += down[1] * 1024 * 1024;
    else if (down[2] == "GB") down_total += down[1] * 1024 * 1024 * 1024;

    if (up[2] == "B") up_total += up[1];
    else if (up[2] == "KB") up_total += up[1] * 1024;
    else if (up[2] == "MB") up_total += up[1] * 1024 * 1024;
    else if (up[2] == "GB") up_total += up[1] * 1024 * 1024 * 1024;

    count++;
}
END {
    print "Sum of down traffic on Snowflake: " down_total / 1024/ 1024 / 1024 " GB";
    print "Sum of up traffic on Snowflake: " up_total / 1024 / 1024 / 1024 " GB";
    print "Total connections established: " count
}'

now it's correct:
root@DietPi:~# ./snowstats.sh
Sum of down traffic on Snowflake: 69.8545 GB
Sum of up traffic on Snowflake: 3.73765 GB
Total connections established: 100

I'm using this to run snowflake:

https://gitlab.torproject.org/tpo/anti-censorship/docker-snowflake-proxy

I updated this script to work with the newest version of the snowflake docker. Also changed it to only show stats for the past 24 hours, and cleaned up the output to look a bit better for the terminal (and in my case a widget for the KDE Plasma 6 desktop too).
