while sleep 1; do
  attemps=$(grep -A 2 "KAFKA_CLIENT_PRODUCER_ATTEMPT" /srv/minted/logs/www-wsgi.log | grep -c "KAFKA_CLIENT_PRODUCER_ATTEMPT")
  sent=$(grep -A 2 "KAFKA_CLIENT_PRODUCER_GOOD" /srv/minted/logs/www-wsgi.log | grep -c "KAFKA_CLIENT_PRODUCER_GOOD")
  fail=$(grep -A 2 "KAFKA_CLIENT_PRODUCER_BAD" /srv/minted/logs/www-wsgi.log | grep -c "KAFKA_CLIENT_PRODUCER_BAD")
  echo $sent / $attemps
done;

the result looks like this:

(mono-venv) root@web-devxenial:/home/vagrant# sudo service uwsgi restart
(mono-venv) root@web-devxenial:/home/vagrant# while sleep 1; do   attemps=$(grep -A 2 "KAFKA_CLIENT_PRODUCER_ATTEMPT" /srv/minted/logs/www-wsgi.log | grep -c "KAFKA_CLIENT_PRODUCER_ATTEMPT");   sent=$(grep -A 2 "KAFKA_CLIENT_PRODUCER_GOOD" /srv/minted/logs/www-wsgi.log | grep -c "KAFKA_CLIENT_PRODUCER_GOOD");   fail=$(grep -A 2 "KAFKA_CLIENT_PRODUCER_BAD" /srv/minted/logs/www-wsgi.log | grep -c "KAFKA_CLIENT_PRODUCER_BAD");   echo $sent / $attemps; done;
