Are these nodes clustered or not?

The management plug-in will report on all nodes in a cluster, assuming 
the rabbitmq-management-agent plug-in is enabled on them, but it cannot 
report on nodes across different clusters.

The OP is running multiple nodes on a single machine. The default 
'enabled plugins' file location is 
${install_prefix}/etc/rabbitmq/enabled_plugins, which means it is 
*shared* between all nodes on that machine. The same goes for the 
rabbitmq.config file. So it's not immediately obvious how one would go 
about enabling/disabling the management plug-in for specific nodes in 
such a setup, or configure different ports for it.

One could possibly make the file locations node specific by construction 
a rabbitmq-env.conf file that sets CONFIG_FILE/ENABLED_PLUGINS_FILE 
based on the node name.
