Yup, that's the next question: what's your recv channel in gmond.conf
on that node? You can just send along the whole gmond.conf if you're
not sure.
If you set the metrics to be logged to a file, do they appear there?
I.e., have you verified the metrics are working at all for the node?

My hadoop-metrics looks like this:

(That is, I'm using the multicasting address as specified in my
gmond.conf:
[..]
udp_send_channel {
mcast_join = 239.2.11.42
mcast_if = eth1
port = 8649
ttl = 1

udp_recv_channel {
mcast_join = 239.2.11.42
mcast_if = eth1
port = 8649
bind = 239.2.11.42

[..])
