The README doesn't explain what this repo is for.

I ran this script on my RHEL8 bare metal host. All of the smartctl commands fail. Here is the output from all of those commands:

Seems we're getting bogus output from one of the lab machines:

Would it be better to use go to execute smartctl and parse the output instead of bash? I started working on a golang version in a temporary location here: https://github.com/pgier/smartmon-text-collector

If it would be helpful, I can create a PR to this repo with similar content.

We need to add some tests for the smart output parser, with some sample data.
