Monitoring your HDD using SMART and Nagios

“Monitoring of your computer systems is a good idea. There are many tools that let you verify that specified services are running, and available for clients. I use Nagios. You can check that Apache is still running, Postfix is still accepting mail, and various other things. If you can write a test, Nagios can monitor it.

Typically, people monitor network connections, applications, and bandwidth consumption. Until recently, I did not monitor disk health. That recently changed.
