smartmontools for NVMe devices

Hi,
NVMe Spec provides for a SMART/Health Log Page. We would like to use
smartctl for reading the Health Log Page as it is a standard OSS util for
monitoring disks. I have some very basic queries related to that.

- Does smartmontools have any support/plan for NVMe devices?

- When I run smartctl on my NVMe device, I get the following output:

#smartctl -d scsi --all /dev/nvme0n1

-- snip snip --- (after displaying some basic device info)
SMART support is:     Unavailable - device lacks SMART capability.
-- snip snip --- (after displaying device temperature)
Error Counter logging not supported
[GLTSD (Global Logging Target Save Disable) set. Enable Save with '-S on']
Device does not support Self Test logging


Does this mean that the device needs to implement something like Section
4.21 in
http://www.t13.org/documents/UploadedDocuments/docs2008/D1699r6a-ATA8-ACS.pd
f ?

- Is it possible to support reading NVMe devices SMART/Health Log Page if
there is no support for SMART in the device?
Will be happy to provide a patch if there is some way to implement this for
NVMe devices without SMART support.

TIA,
-Indro
