I would agree with this. I hadn't taken the time to read the man for smartctl and understand the output from smartctl -a until I saw this article, and I'm glad I now have. Since I work with a lot of clients that do all on-premise virtualization, it's helpful to be able to quickly get an idea of where a disk is at as far as SMART is concerned. Most of the vendor tools leave a lot to be desired, IMO, or have inconsistent metrics, so it's nice to just be able to point straight at what the source data from the attributes says.
