The below is for setting up unicast, not multicast. AWS does not support multicast networking.

Key concepts: gmond daemons run on every server and use C code to collect the server's stats; this data is stored in local memory. Multiple gmonds can send their data on to one central gmond to hold, call this a gmond "bank"; this "bank" also uses only memory to store the server stats. gmetad comes along and collects the data from the gmond "banks" and stores in it rrds, these are files; the web interface uses these rrd files, and it usually runs on the same server as gmetad.

Cluster name: cluster name is key in grouping data and getting it from gmond to gmond and then on to gmetad. data_source is the way gmetad find the "banks"; and, by the way, you can have redundant "banks" for one cluster data_source.

Getting rid of multicast settings: comment out all references to multicast: bind_hostname, mcast_join, bind. Comment them all out.
