Error with VIF_METRICS

Hello everybody,

I need to get VIF_metrics from a specific VM and I got a problem while
trying to do that.

(HANDLE_INVALID VIF_metrics OpaqueRef:f71830ff-301b-77a8-37e9-f4c4aaa2905b)

It is very strange, I never got this error before.
Take a look on my code:

$vms_array = $xenserver->VM_get_all();

foreach ($vms_array as $vm) {
$record = $xenserver->VM_get_record($vm);
if($record['is_a_template']==false &&
$record['is_control_domain']==false) {

var_dump($record['VIFs']); //Return : 0 => string
'OpaqueRef:f71830ff-301b-77a8-37e9-f4c4aaa2905b' (length=46)

foreach($record['VIFs'] as $vif) {
* $metrics =
$xenserver->__call('VIF_metrics.get_record',array($vif) ));
var_dump($metrics);
* }
}
}

I tried many values as parameter but no success...

Anybody here knows what is this problem?
Thanks

Re: Error with VIF_METRICS [In reply to]

Hi Luiz,

The VIF_metrics is a separate object from the VIF itself - my perl is not very good, but in python I'd do something like this:

vms = session.xenapi.VM.get_all()

for vm in vms:
vm_record = session.xenapi.VM.get_record(vm)
if record["is_a_template"] == False and record["is_control_domain"] == False:
for vif in vm_record["VIFs"]:
metrics = session.xenapi.VIF.get_metrics(vif)
if metrics != "OpaqueRef:NULL":
metrics_record = session.xenapi.VIF_metrics.get_record(metrics)
# do something with metrics_record...

Re: Error with VIF_METRICS [In reply to]

Hello

That's exactly I did..

But no success..
To get the VIF metrics now I'm doing a CURL at /vm_rrd ..

Is that a right way do get the VIF metrics stats?

How can I get the assigned IP for this Interface? (by xencenter I can
see the IP, but and with API, how?)

Thanks

Re: Error with VIF_METRICS [In reply to]

Hi,

I believe the IP is the "VM_guest_metrics" since it comes from the guest agent. Have a look in the "networks" map.

Cheers,
