Which metrics are being reported (which collector)?

Keep in mind that some metrics apply to the physical device, so they are applicable even if the filesystem on that device is not mounted; the device might be used raw by some application. Conversely, some metrics that apply to physical devices don't exist for tmpfs, which does not emulate a block device at all.
