Off-hand, that appears to be correct.

I think I am a bit unclear as to what exactly you are trying to achieve here.
If you configure the second node's gmond.conf to send to itself
(192.168.0.221), then the first node will never receive any metrics from it,
and it won't appear in the web interface. But you say that when you configure
the second node to send metrics to the first node, it doesn't work. Can you
explain more about what doesn't work?
I recommend trying this configuration:
gmond.conf on 192.168.0.220:
udp_send_channel {
host = 192.168.0.220
port = 8649
}
udp_recv_channel {
port = 8649
}
tcp_accept_channel {
port = 8649
}
gmond.conf on 192.168.0.221:
udp_send_channel {
host = 192.168.0.220
port = 8649
}
udp_send_channel {
host = 192.168.0.221
port = 8649
}
udp_recv_channel {
port = 8649
}
tcp_accept_channel {
port = 8649
}
On 192.168.0.221, you should be able to run "telnet localhost 8649" and see
the metric data for that host. On 192.168.0.220, you should be able to run
"telnet localhost 8649" and see the metrics for both hosts. If that doesn't
work, then you may need to take a closer look at your network to make sure
that packets are being sent between the hosts properly.
