Hi, I am trying to configure Ganglia on a cluster with a frontend and some compute nodes. At first, I want to setup the frontend, so that I can see its' information on the web interface. But there are some confusing points with that. Specifically, I don't know how to specify data source!
Please see the outputs below which are from frontend root@cluster:~# cat /etc/ganglia/gmetad.conf data_source "cluster" 172.20.54.10 RRAs "RRA:AVERAGE:0.5:1:2440" "RRA:AVERAGE:0.5:4:1440" "RRA:AVERAGE:0.5:17:2440" "RRA:AVERAGE:0.5:67:2440" \ "RRA:AVERAGE:0.5:576:3740" root@cluster:~# cat /etc/hosts 127.0.0.1 localhost.localdomain localhost 10.10.10.1 cluster.abc.edu cluster.local cluster 10.10.10.254 compute-0-0.local compute-0-0 10.10.10.253 compute-0-1.local compute-0-1 10.10.10.252 compute-0-2.local compute-0-2 10.10.10.251 compute-0-3.local compute-0-3 root@cluster:~# ifconfig eth0 Link encap:Ethernet HWaddr 00:E0:81:C6:D5:35 inet addr:10.10.10.1 Bcast:10.10.10.255 Mask:255.255.255.0 eth1 Link encap:Ethernet HWaddr 00:E0:81:C6:D5:34 inet addr:172.20.54.10 Bcast:172.20.54.255 Mask:255.255.255.0 Now, as I start gmetad, I see this errors: root@cluster:~# /opt/ganglia/sbin/gmetad -d 10 Going to run as user nobody Sources are ...

Why it failed?
