Hi Hardik,

You can replace the sections with mcast_join with these:

udp_send_channel {
  host = foo01.plaxo.com
  port = 8649
}
udp_send_channel {
  host = foo02.plaxo.com
  port = 8649
}
udp_recv_channel {
  port = 8649
  family = inet4
}
tcp_accept_channel {
  port = 8649
}

The config above is for the gmond instance(s) that'll receive info from 
other gmonds in the same cluster. Then you can configure gmetad to poll 
gmond in foo02 and foo02 (in this case).
