Discovering and Monitoring Hardware in Linux

Nothing ever need be a mystery on Linux as it has a large number of excellent utilities for discovering hardware and monitoring hardware health. Here are a handful of good tools for spotting possible hard drive failure, displaying hardware information and monitoring temperatures, fans, voltages, email, music players and more.

You're probably familiar with the excellent smartmontools for monitoring hard drive health, and getting early warning of possible drive failure. Smartmontools runs tests and reads data on drives that have the Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) system built into them. It's been around seemingly forever, but did you know there is a graphical interface for it? SmartControl puts a nice interface on smartmontools and supports all of its functions.
