good day all,
i'm having a bit of trouble getting 3.1.2 running correctly on my cluster. its
an SLES10sp2 x86_64 cluster. i have gmetad and gmond running oh head node, and
gmond running on nodes 1 and 2. the head node is multihomed as usual with eth0
the internal network:
viper:/etc/ganglia # netstat -ar
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
239.2.11.71 * 255.255.255.255 UH 0 0 0 eth0
xxx.xxx.xxx.xxx * 255.255.252.0 U 0 0 0 eth1
link-local * 255.255.0.0 U 0 0 0 eth0
172.16.0.0 * 255.255.0.0 U 0 0 0 eth0
172.17.0.0 * 255.255.0.0 U 0 0 0 ib0
172.17.0.0 * 255.255.0.0 U 0 0 0 ib1
loopback * 255.0.0.0 U 0 0 0 lo
default defaultrouter 0.0.0.0 UG 0 0 0 eth1
and i've fixed gmond to eth0 on the head node with:
/* Feel free to specify as many udp_send_channels as you like. Gmond
used to only support having a single channel */
udp_send_channel {
mcast_if=eth0
mcast_join = 239.2.11.71
port = 8649
ttl = 1
}
/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
mcast_if=eth0
mcast_join = 239.2.11.71
port = 8649
bind = 239.2.11.71
}
i've left the gmond.conf the default i made with gmond -t other than changing
the name of the cluster in the cluster container:
/*
* The cluster attributes specified will be used as part of the <CLUSTER>
* tag that will wrap all hosts collected by this instance.
*/
cluster {
name = "Viper Cluster"
owner = "mgx"
latlong = "unspecified"
url = "unspecified"
}
the head node and nodes all report only themselves with gstat
node001:~ # gstat -a

the network on the nodes looks like this:
node001:~ # netstat -ar

link-local * 255.255.0.0 U 0 0 0 eth0

loopback * 255.0.0.0 U 0 0 0 lo
default viper 0.0.0.0 UG 0 0 0 eth0
i'm clearly missing something simple, but i sure cannot see what it is at this
point,
any help greatly appreciated.
