I also had issues with Ganglia only seeing my head node once I updated my
gmetad and gmond packages to the latest versions. Running the post_install
script didn't help reconfigure everything correctly at all. The head node
was running on 2 network cards (1 for WAN access, and 1 connected to the
internal compute node network), and for some reason gmetad was listening on
the wrong interface, hence the reason it was only picking up meta-data from
itself but not the compute nodes on the second interface. After some
searching, I found that you can add an option in your gmond.conf file to
explicitly specify which interface your daemon is listening/sending on.
Snippet from my gmond.conf file:
udp_send_channel {
mcast_if = eth1 <===============THIS OPTION
mcast_join = 239.2.11.71
port = 8649
ttl = 1
}
udp_recv_channel {
mcast_if = eth1 <============= THIS OPTION
mcast_join = 239.2.11.71
port = 8649
bind = 239.2.11.71
}

Subject: Re: [Oscar-users] Gangila Set up Fail in Test Cluster Setup
Hi,
I do the steps you point out. But Ganglia Setup Test fail in the Test
Cluster Setup.
But I can see sometime all nodes in http://localhost/ganglia. I can't
see sometime all nodes in this page. I see only one node.
I don't think how to solve that problem.
when I reboot the clients node, I see the 2 errors :
(1) Set up Postfix fail
(2)Set up NTP fail
How can I fix these problem? Are these problems relate to Ganglia fail?
Thank you so much for your patience attention.
