Hello,
I installed ganglia 3.0.0 on the head node of my cluster using the rpm files.
The installation is fine. However, on the website it shows that the CPUs
Total: Hosts up: 0. It seems the ganglia could not see the node. I also tried
gstat:
[EMAIL PROTECTED] etc]# gstat
CLUSTER INFORMATION
Name: unspecified
Hosts: 0
Gexec Hosts: 0
Dead Hosts: 0
Localtime: Wed Mar 1 10:47:54 2006
There are no hosts running gexec at this time
And telnet localhost 8649. It didn't show any metrics on the telnet:

<GANGLIA_XML VERSION="3.0.0" SOURCE="gmond">
<CLUSTER NAME="unspecified" LOCALTIME="1141228133" OWNER="unspecified"
LATLONG="unspecified" URL="unspecified">
</CLUSTER>
</GANGLIA_XML>
I used the default gmond.conf, which is showed as following. Do anyone know
what's the problem? Thanks.
