We are trying to query the rhevm/oVirt engine for the storage allocation/actual usage numbers for

1. Host 2. Virtual Machine (we can have allocation size from virtual disks associated with VM, but not the actual usage) 3. Cluster

Is there a ReST API that can fetch this information?

The basic information is available in the disk resource: /api/disks/{disk:id} /api/vms/{vm:id}/disks/{disk:id} There you will find three values: <size>...</size> <provisioned_size>...</provisioned_size> <actual_size>...</actual_size> I think that the <actual_size> is what you are looking for. For a particular storage domain you can also see some aggregated information, in tue /api/storagedomains/{storagedomain:id} resource: <available>...</available> <used>...</used> <committed>...</committed> -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.
