Hi, I am developing a Xen management application only using the Xen API as it seemed complete enough to use for the whole application, and indeed it is. However, when trying to acquire a VM_guest_metrics reference (Debian, Xen 4.1-amd64 and Xen 4.1-i686 with XAPI) for a VM, the getter returns MESSAGE_METHOD_UNKNOWN and the reference isn''t included in VM.get_record either. That said, wouldn''t it be better to make the actual memory use available through the VM_metrics memory_actual -- I know Xen always reserves the full amount of memory needed, but this also renders the variable useless because it''ll probably resemble VM.memory_static_max if there is enough RAM to go around. So the question remains: how can I, using only the Xen API, acquire VCPU and memory load -- preferably without the need to install anything? It would be rather unpleasant having to create and install some simple daemon just to send load numbers over to my backend.
