RabbitMQ

Alternative version also provided, which uses rabbitmqctl instead of REST API of management-plugin. This could be useful when management-plugin leaks memory or timeouts requests. Also rabbitmqctl provides atom tab stats, but as it is ran by root - you also need to add to cron:

$ cat /etc/cron.d/rabbit-status
*/3 * * * * root /etc/zabbix/rabbitmqctl-status.sh
*/5 * * * * root /etc/zabbix/rabbitmqctl-status.sh queues

Unfortunately rabbitmqctl lacks some info provided only by REST API, for example - rates. This could be send as traps by adding one more line to cron:

* * * * * root /etc/zabbix/rbrates.py
