[Xen-API] xen_vm_get_guest_metrics error

["gaoshuang" <gaoshuang@xxxxxxxxxx>]

hi

    i tried to get vm guest metric by calling xen_vm_get_guest_metrics(session, &vm_guest_metrics, vm), and i got the error messages:

   Error: 2
   MESSAGE_METHOD_UNKNOWN
   VM.get_guest_metrics

 

    i'm usning xen 3.1, is there something i can do? i don't know what's the problem.

 

    another question. i called xen_pif_get_all and xen_pbd_get_all, but the returned pif set and pbd set are all sized zero. Is there any way i can get the host's physical network and disk utilisation?

 

 

thanks:)

Vivienne
