Sensu / Nagios compatible plugin to check RabbitMQ queue item counts. Requires RabbitMQ management plugin to be enabled:
$ rabbitmq-plugins enable rabbitmq_management
$ check-rabbitmq -host http://somehost:15672 \
-user admin -password secret
-error 10 -warn 5 \
-queue 'pattern' \
-exclude '^some_queue$'
