- Introduction

So you have your new Linux-based system up and running. But you also need to monitor its status and be prepared for possible failures or determine causes of hardware instability. Modern PCs support a variety of tools to help you, and you'll be surprised to learn that with a few simple applications you can probe a number of functional parameters, like hard drive temperature, CPU fan speed and GPU clock. The list of tools shown here is by no means exhaustive, but should serve as a reasonable starting point for most desktop systems. There are more sophisticated tools to be found for server use, or ones which address highly specific needs.

- SMART status

Modern hard drives constantly monitor their functional parameters, including temperature, power-on hours, reallocated sector count, hardware ECC recovered data using a technology known as SMART. As a matter of fact, S.M.A.R.T. is an acronym for “Self Monitoring Analysis and Reporting Technology”. Recent research has shown that some of the SMART attributes may be useful for predicting hard drive failures. As a general rule, even though hard drives frequently fail abruptly, without previous indication of malfunction, the existence of a SMART error greatly increases the probability of failure. Specifically, scan errors, sector reallocations and sector probational counts mean that the drive is very likely to fail within 60 days.

Fortunately, you can use a simple set of tools called “smartmontools” that allow you to view this information, store it in a log file, periodically run automatic hard drive tests and even receive automatically generated email warnings in case of hard drive errors. Smartmontools can be obtained from Sourceforge (source version) but it is probably already included in your favorite distribution.

After the installation you can probe your hard drives for information with the following simple command:
