I do not have a lot of success in getting Ganglia to work on cluster
of 22 computers.
It is an OpenSuse system and I have installed gmond on all the nodes
and it is running an all the nodes.
On the head-node I have the following in /etc/ganglia/metad.conf:
data_source "Ratashasta" localhost:8649 192.168.129.2:8649 192.168.129.3:8649
192.168.129.4:8649 \
192.168.129.5:8649 192.168.129.6:8649 192.168.129.7:8649 192.168.129.8:8649
192.168.129.9:8649 \
192.168.129.10:8649 192.168.129.11:8649 192.168.129.12:8649 \
192.168.129.13:8649 192.168.129.14:8649 192.168.129.15:8649 \
192.168.129.16:8649 192.168.129.17:8649 192.168.129.18:8649 \
and
trusted_hosts 127.0.0.1 192.168.129.2 192.168.129.3 192.168.129.4 \
192.168.129.5 192.168.129.6 192.168.129.7 192.168.129.8 192.168.129.9 \
192.168.129.10 192.168.129.11 192.168.129.12 \
192.168.129.13 192.168.129.14 192.168.129.15 \
192.168.129.16 192.168.129.17 192.168.129.18 \
192.168.129.19 192.168.129.20 192.168.129.21 192.168.129.22
When I run sudo gstat -a
The result is:
CLUSTER INFORMATION
Name: Ratashta
Hosts: 1
Gexec Hosts: 0
Dead Hosts: 0
Localtime: Wed Nov 26 15:48:15 2008

OFF
I have changed the firewall through yast to allow udp traffic from
146.232.128.108/32 on port 8649 as well as from 192.168.129.0/24 (the
nodes on internal network.
I have gmond running an all the nodes.
I don't see that IPTABLES is blocking communication between the
head-node and the other and I don't know what to look for next.
Any help will be appreciated.
Regards
Johann
