I try to use the different port. But all nodes contains in one list.
What is the problem? Must I run the gmetad daemon on main nodes of
clusters? Please send to me a example of configuration files.
P. S.
I used the next configurations:
cluster {
name = "cluster1"
}
udp_send_channel {
host = 127.0.0.1
port = 8649
}
cluster {
name = "cluster2"
}
udp_send_channel {
host = 127.0.0.1
port = 8648
}
cluster {
name = "cluster3"
}
udp_send_channel {
host = 127.0.0.1
port = 8647
}
