<br>
Thanks for this feedback.<br>
<br>
My request wasn't clear enough, I already monitor my hosts and
I see the OPENNEBULA-VMS-INFORMATION variable in Ganglia, but
I don't know how to use it to provide graphs on the VM usage.<br>
<br>
Will the VM information be displayed in Sunstone ? In Ganglia
? <br>
</font></div>

<font face="arial">OPENNEBULA-VMS-INFORMATION provides global VM
status information to opennebula. Some graphs are available in
Sunstone to monitor the VM help with this data (when you click on
your vm in suntone)<br>
<br>
If you want Ganglia monitoring of your VM, you have to setup gmond
in the VM itself.<br></font></div></blockquote><div><br></div><div>Or one can use Host sFlow [1] to gather CPU, RAM and network statistics. There is a blog post [2] describing the installation procedure. Works with Ganglia 3.2+. If you need other metrics you'd have to install gmond inside the VM. Enjoy.</div>

<div><font face="arial">Dear
mailing-list, (these days it's like saying "dear
Santa," <img alt=":)"> )<br>
<br>
I've set up a ganglia environment in my lab and can
see the monitoring information for my hosts.<br>
<br>
I've followed the manual about ganglia integration and
updated the nodes, updated oned.conf, created the cron
as follow :<br>
<br>
*/1 * * * * oneadmin gmetric -n
OPENNEBULA_VMS_INFORMATION -t string -v
`/var/lib/one/remotes/vmm/kvm/poll --kvm`<br>
<br>
I've updated the probe file to point to my central
ganglia server.<br>
<br>
But I can't see anything on Ganglia web.<br>
<br>
I might be missing something on the ganglia server
side... but what ? Where are the VM information
defines for Ganglia to display them ?<br>
</font></div>
</blockquote>
<font face="arial">Ganglia does not provide graphics for the
VMs with opennebula. VM information are stored in a
variable accessible for each host with name </font><font face="arial">OPENNEBULA_VMS_INFORMATION (base64 encoded).<br>
Then opennebula will trigger ganglia to get the status of
the VMs running on this host.<br>
<br>
OpenNebula uses Ganglia to extract the information, and
not the contrary<br>
<br>
If you want to monitor your host with Ganglia you can use
standard metrics provided by gmetric (cpu,ram,...)<br>
