Ok – I gave the
DomU 2 CPUs and got the following result for VM_metrics.get_record():
Array
(
[VCPUs_params] => Array
(
[cpumap1] => 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31
[cpumap0] => 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31
[cap] => 0
[weight] => 256
)
[last_updated] => 20070816T19:55:34
[uuid] => 30c8c9f5-6d8d-2f05-32d1-423cb2054d97
[VCPUs_flags] => Array
(
[1] => Array
(
[0] => blocked
[1] => online
)
[0] => Array
(
[0] => blocked
[1] => online
)
)
[start_time] => 20070816T19:51:43
[memory_actual] => 268435456
[state] => Array
(
[0] => blocked
)
[VCPUs_utilisation] => Array
(
[1] => 102
[0] => 0.00037114269606261139
)
[VCPUs_number] => 2
[VCPUs_CPU] => Array
(
[1] => 0
[0] => 1
)
)
Why is there only one
state for both CPUs? Or is this an aggregated value for all VCPUs.
What does the CPU
Utilisation 102 mean? I supposed to be a percentage value to be between
0.0-1.0.

Betreff: Re: [Xen-API] power state
evaluation
If
I call VM.get_record() I get an key named
[power_state] => Running
This is the power state of the vm ie running, halted,
suspended etc.
If
I fetch the metrics by VM_metrics.get_record() I get a similar information:
[state] => Array
(
[0] => running
)
These are the individual statues of the vcpus, ie
running, paused, blocked etc
