No, I don't think so.
I have a server that collects metrics from three different ganglia
"clusters", and just have multiple udp_recv_channel stanzas, one for
each unicast port, and another for each multicast port. I only have
gmond process running, bound to multiple ports. For example:
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8649 /* cluster */
bind = 239.2.11.71
}
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8648 /* workstations */
bind = 239.2.11.71
}
udp_recv_channel {
port = 8649 /* cluster */
}
udp_recv_channel {
port = 8648 /* workstations*/
}
# lsof -i |grep gmond
gmond 3950 nobody 3u IPv4 32629 UDP 239.2.11.71:8649
gmond 3950 nobody 4u IPv4 32633 UDP 239.2.11.71:8648
gmond 3950 nobody 6u IPv4 32635 UDP *:8648
gmond 3950 nobody 7u IPv4 32636 UDP *:8649
gmond 3950 nobody 8u IPv4 32637 TCP *:8649 (LISTEN)
Now, the gmond.conf files in the "cluster" and "workstation" groups
are different, since they need to send to differen port numbers.

Every cloud has a silver lining, except for the mushroom-shaped ones,
which come lined with strontium-90.
