It's not on a machine I have access to right now, but I'm fairly certain it went something like:

    while [ "true" ]
    do
        printf 'google_ping %f %s' $(ping -c1 www.google.com | awk '/ms/ {print $7};' | awk -F '=' '{print $2};') $(date +%s) | nc graphite_host 2003
        sleep 10
    done
