If you’re trying to set up multiple munin nodes in EC2, you need to use the internal hostname to reference slave nodes.

munin.conf

[web01]
    address domU-22-31-38-12-25-04.compute-1.internal
    use_node_name yes

munin-node.conf

host_name web01
allow ^.*$

Voila!

Also be sure to open 4949 if you’ve got a security group set up.
