presume that you are referring to some other report from ganglia 3.1
not being able to get its own data here based on the subject, but
the behaviour observed is from 3.0 based on the body, could you provide a
reference to the original report as it might be an unrelated problem.
running `gmond -d10` should generate a log of what is going on that
could help trace the problem, but from the configuration shown below it might
be just an unintended misconfiguration.

you have to match the mode used (multicast or unicast) for udp_send_channel
and udp_recv_channel even if we allow the configuration of mismatching sets
which will result in problems like the one you are observing (that is a bug)
but mainly because the flexibility of the configuration allows for some
strange settings that we would be otherwise not able to predict (like having
additional unicast messages sent somewhere different than a gmond for reporting)
the following should work in your case :
* plain multicast configuration as used by default (you need multicast support
working for your system and enabled/routed correctly)
udp_send_channel {
mcast_join = 239.2.11.71
port = 8649
ttl = 1
}
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8649
}
* plain unicast configuration through localhost (not what you want in the long
run as it will use "localhost" as the node name)
udp_send_channel {
host = 127.0.0.1
port = 8649
}
udp_recv_channel {
port = 8649
}
* plain unicast configuration through working interface (assuming that
10.50.54.31 is configured in one of your interfaces)
udp_send_channel {
host = 10.50.54.31
port = 8649
}
udp_recv_channel {
port = 8649
}
