Greetings, I have an 18 node cluster (1 master node, 17 slave nodes), and I am running the cluster on the 192.168.0 private network. The master node is 192.168.0.1, and the slave nodes are 192.168.0.1xx. I have installed ganglia-gmetad and ganglia-web on the master node, and ganglia-gmond on each of the slave nodes. The only change from the default installation of gmetad on the master node are the lines
data_source "RayleighCluster" 192.168.0.1 gridname "RayleighGrid" trusted_hosts 127.0.0.1 all_trusted on The gmond is the default installation on the master node and all slave nodes. All nodes have two network interfaces. The masternode's eth0 is a connection to the outside world, and the slave nodes eth0 is used only for booting via PXE off the master. All nodes' eth1 is used to connect to the private network (192.168.0). I have performed a route command to add 239.2.11.71 to eth1 on the master node. The output of '/sbin/route' on the master node looks like this: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 239.2.11.71 * 255.255.255.255 UH 0 0 0 eth1 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 131.215.42.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth1 default default-42.calt 0.0.0.0 UG 0 0 0 eth0 The Ganglia output can be seen here: http://rayleigh.cds.caltech.edu It looks like all the data from all the nodes is lumped together. Nothing happens when I select an individual node or try to change metrics. How can I get Ganglia to display colored output of each node, rather than showing the cumulative output 18 times. Thanks.
