# OLD BASH SCRIPT
# ---------------

# (1) Empty only monitoring queue:
#celery -A pyros amqp queue.purge monitoring_q

# (2) Empty ALL queues
#celery -A pyros purge -f

# (3) THE HARD WAY : something like that...
#ps aux | grep \"celery worker\" | awk '{print $2}' | xargs kill -9



# NEW PYTHON SCRIPT
