S.M.A.R.T. Input Plugin: Some attributes not collected on NVMe drive

[split-n]

Relevant telegraf.conf:

[[inputs.smart]]
    use_sudo = true
    attributes = true

System info:

• Telegraf 1.14.5 (git: HEAD e77ce3d)
• Proxmox VE 6.2
  • It's based on Debian 10.4
• smartmontools 7.1-pve2

Steps to reproduce:

1. Enable SMART plugin on config to collect attributes
2. Start telegraf service or Run sudo -u telegraf telegraf --input-filter=smart --test

Expected behavior:

Attributes like "Data Units Written" should be collected because it's defined and tested to be collected.

telegraf/plugins/inputs/smart/smart.go

Line 121 in cd97534

"Data Units Written": {

telegraf/plugins/inputs/smart/smart_test.go

Line 678 in cd97534

"name": "Data_Units_Written",

Actual behavior:

Only a few attributes collected. (What I need is to collect Data_Units_Written).

Additional info:

It looks like #6032 is a similar issue.

I realized that support for missing attributes had added recently on #7575 that's not included in Telegraf 1.14.5. And it works on Telegraf 1.15-RC2. Close this issue.
