I made the changes you advise me => it seems to work well now!!! But I'm newbie in network and I don't understand why
Is each node of the same (imagine I want to add e node to a cluster) need to have same m_cast port ??? What is the duty oh the name give in /etc/gmetad.conf (ex : datasource "My production nodes" 10.0.0.1), the name of the data source seems to be never used by ganglia web-frontend ???

The headnode that you are displaying from needs gmond, gmeta, and ganglia-php-rrd running. The other two nodes only need gmond running. If it is still not working, did you restart all the daemons? You should have a different mcast_port number on each node (I use 8649, 8650, and 8651). For example, I have a set of Itanium-2's using 8650: quad2:~# grep mcast /etc/gmond.conf mcast_if eth0 mcast_port 8650 "gstat" only shows Itanium-2's that use 8650. This behavior is key. "gstat" must only show a single node. gmetad uses the same information. Then, from my head node, if I "telnet quad2 8649 > /tmp/junk" The only nodes shown are from that cluster. For you, you should only see a single node. If each node has a different mcast_port, then gstat should only show the each node from itself. Is that happening? Can you send the /etc/gmond.conf from each node, plus the output from gstat? Did you stop/start gmond after changing /etc/gmond.conf? It is NOT dynamic.
