Hello everyone,
I was reading the Measurements doc today, I got a bit confused about some
measurements. such as :
disk.capacity and disk.device.capacity
the disk.capacity explanation: The amount of disk that the instance can
see.
the disk.device.capacity explanation: The amount of disk per device that
the instance can see.
I do not know what is the ‘device’ here.
I grap the disk info here:
DiskInfoData(capacity=21475325952L, allocation=19580554752L,
physical=21475325952L, per_disk_info={'allocation': {'vda': 19580554752L,
'hdd': 0L}, 'capacity': {'vda': 21474836480L, 'hdd': 489472L}, 'physical':
{'vda': 21474836480L, 'hdd': 489472L}})
are these vda and hdd stand for different device?
what is the different between disk and disk.device? could you give me some
helps?
Best regards
Shengping
