Parameter Name Description Type
start-time timestamp of the date and
time that the metrics for the
VM were read, in the form
yyyymmddThh:mm:ss z,
where z is the single-letter
military timezone indicator, for
example, Z for UTC (GMT)
read only
install-time timestamp of the date and
time that the metrics for the
VM were read, in the form
yyyymmddThh:mm:ss z,
where z is the single-letter
military timezone indicator, for
example, Z for UTC (GMT)
read only
memory-actual the actual memory being
used by a VM
read only
VCPUs-number the number of virtual CPUs
assigned to the VM
For a paravirtualized Linux
VM, this number can differ
from VCPUS-max and can be
changed without rebooting
the VM using the vm-vcpu-
hotplug command. See the
section called “vm-vcpu-
hotplug”. Windows VMs
always run with the number
of vCPUs set to VCPUs-max
and must be rebooted to
change this value.
Note that performance
will drop sharply if you set
VCPUs-number to a value
greater than the number
of physical CPUs on the
XenServer host.
read only
VCPUs-Utilization a list of virtual CPUs and their
weight
read only map parameter
os-version the version of the operating
system for the VM
read only map parameter
PV-drivers-version the versions of the
paravirtualized drivers for the
VM
read only map parameter
