Redid the way of how zabbix-sender is being used. 

Hey!

I'd used your idea of RabbitMQ monitoring and noticed that you call zabbix_sender so oooooooften! We have big overhead when you have, saying, 20...40 queues. I propose to collect all the data into single file and then use zabbix-sender once in order to send the data back to the Zabbix Server.
