ganglia-集群的配置

gmetad：

data_source "Namenode" 192.168.1.28:8653
data_source "Datanode" 192.168.1.27:8649
data_source "Portal" 192.168.1.43:8650
data_source "Collector" 192.168.1.35:8651
data_source "DB" 192.168.1.51:8652

gmond：

cluster {
    name = "Portal"
    #对应gmetad中的Portal，名称一定要写对。
    owner = "unspecified"
    latlong = "unspecified"
    url = "unspecified"
}
/* Feel free to specify as many udp_send_channels as you like.    Gmond
     used to only support having a single channel */
udp_send_channel {
    #bind_hostname = yes # Highly recommended, soon to be default.
                                             # This option tells gmond to use a source address
                                             # that resolves to the machine's hostname.    Without
                                             # this, the metrics may appear to come from any
                                             # interface and the DNS names associated with
                                             # those IPs will be used to create the RRDs.
    mcast_join = 239.2.11.71
    port = 8650
	#gmetad中的Portal所分配的端口号。
    ttl = 1
}

/* 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
}

/* You can specify as many tcp_accept_channels as you like to share
     an xml description of the state of the cluster */
tcp_accept_channel {
    port = 8650
}

不同的集群需要用不同的端口

只需配置队长节点，其他节点只需要端口和集群名相同，便可以自动加到同一个集群里
