I also had a problem with ganglia when setting up an oscar cluster.
I use unicast, with a number of the following sections
udp_send_channel {
/* mcast_join = 239.2.11.71 */
host = 10.0.0.12
port = 8649
}
udp_send_channel {
/* mcast_join = 239.2.11.71 */
host = 10.0.0.11
port = 8649
}
and pointed gmetad at the hosts 10.0.0.11-12
that worked for me.
