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:
