How can I get the usage of my Storage Profiles?

  Hi!

  I'm successfully using VMware PHP vCloud API to gather information from my vCloud Organitzation objects (orgs, vDCs, vShield Edges, vApps, VMs) (my scripts), but how can I get the usage of my Storage Profiles?

  On my tests, I get a reference to a vDC ($vdcRef), then I create a VMware_VCloud_SDK_Vdc object doing:

$sdkVdc = $service->createSDKObj($vdcRef);

  then I get it's StorageProfiles doing

$sdkVdc->getVdcStorageProfiles();

  but this array contains objects of class VMware_VCloud_API_VdcStorageProfileType , which has methods like getEnabled() , getUnits() , getLimit() , getDefault() and getDescription() , but it just shows me the limit (getLimit()), not it's current disk usage.

  Looking at API source, I realize that depending on your authorizations some methods return admin or a non-admin object. For example: on file "VMware/VCloud/Admin.php", you can see that the method getAdminVdcRefs() from VMware_VCloud_SDK_AdminOrg class returns "Admin Vdc references" for "System/Cloud Administrator" but it returns "Vdc references" for "Organization/Tenant Administrators/Users" (that's my case). Maybe if I where and administrator then I could get an object with more information about my Storage Profiles, I don't know.

  Any way, using vCloud Director web user interface I really can get my storage profile's usage. So my account really has permissions to get this information. This way I just can imagine two possibilities:
* or the VMware PHP vCloud API just provides this information to "System/Cloud Administrators"
* or it provides it but I'm not hitting it

  I bet second option :) How can I do it?

  If it's the first option (API is not for me), then at least I may be able to access this information requesting it to the vCloud REST API... but browsing it and folling links I can't get this information. I may be missing something.

  Thanks and best regards!
