Thread-topic: [Xen-devel] RE: Xen Cloud Platform - issues
Hi,

> Should I understand that XCP maintains a set of RRDs on each node ?

Yes -- the convention is that each host maintains its own 'host rrd' as well as 
the 'vm rrds' of the VMs running there. When a VM is started the master pushes 
the 'vm rrd' to the slave; when the VM shuts down the slave pushes the 'vm rrd' 
back to the master.

Cheers,
Dave
