retrieve smart results for disks using the API?

[kfrank]

Is there anyway to retrieve the most recent smart results for disks using the API?
I would like to create a dashboard in home assistant that would show the health of each disk in the pool, not just the health of the pool itself.
Thank you for any help in advance.

I am currently using:
TrueNAS-SCALE-22.12.2 on a Dell R720xd with 16 cores and 32 threads

midclt call disk.smart_attributes sda | jq

That works from the shell... you can figure out the remote rest call syntax from that clue.

This is what I get when I run that from the shell:

Code:

admin@truenas:~$ midclt call disk.smart_attributes sdb | jq
[EFAULT] Only ATA device support S.M.A.R.T. attributes
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/middlewared/main.py", line 196, in call_method
    result = await self.middleware._call(message['method'], serviceobj, methodobj, params, app=self)
  File "/usr/lib/python3/dist-packages/middlewared/main.py", line 1335, in _call
    return await methodobj(*prepared_call.args)
  File "/usr/lib/python3/dist-packages/middlewared/schema.py", line 1318, in nf
    return await func(*args, **kwargs)

    res = await f(*args, **kwargs)

Is sda a SATA/SAS disk?

Does it work on any other devices than sda?

Oh my bad... good point. The drives are all SAS drives so I don't think they support S.M.A.R.T. ‍

I actually was able to retrieve the result of smart test using the api by running:

Code:

curl -X GET -H "Authorization: Bearer <API Key>" http://<trueNAS IP or host name>/api/v2.0/smart/test/results

the response include results such as the following for all of my disks:

Code:

  "tests": [
   {
    "num": 1,
    "description": "Background short",
    "status_verbose": "Completed",
    "segment_number": 64,
    "lifetime": 2,
    "lba_of_first_error": null,
    "status": "SUCCESS"
   },
   {
