With the release of rabbitmq v4.0.1 several I/O related metrics are no longer made available by rabbitmq, among others sockets_used and sockets_total. Previously a default value of 0 being returned for these values lead to a crash of the check plugin with a ZeroDivisionError. Now the service will no longer be discovered. As long as the service is not removed, it will become {CRIT} with the message

No available sockets
