Hello,
I found another way by modifying gmond.conf:
/* You can specify as many udp_recv_channels as you
like as well. */
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8650
bind = 239.2.11.71
}
/* ==>add eth0<==*/
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8650
bind = 239.2.11.71
mcast_if = eth1
}
in this way, I don't need gmetad on node2.
