Changing /dev/sda allows you to check other hard drives on the server. This will provide the temperature for the hard drive /dev/sda. It can only check one hard drive at a time and you need to provide which drive you want to be checked, for example: Using hddtemp is a simpler process as it doesn’t require any setting up, though it does need superuser privileges to be in use. By default the temperatures are in degrees Celsius, but to get the output in Fahrenheit use the -f flag as below: On my system this shows the CPU fan rotation speed, the system temperature and the temperatures of the individual CPU cores. Once configured the following command will give you a listing of the readings from the sensors: Next, it will give you the option for the system to add the relevant configuration options for lm-sensors to read the output, otherwise you’ll need to manually add them for lm-sensors to work. After going through the questions it will provide a list of output of the sensors that it can communicate with. This will ask you to confirm you are happy to probe the various sensor devices on your system for existence. Once installed, both tools are relatively simple to use lm-sensors requires a small amount of configuration to work with your system before you can get the data from it. The install for Debian/Ubuntu and related distributions is:įor Red Hat and CentOS systems you can use: (Self-Monitoring, Analysis, and Reporting Technology) system built into it.įortunately both tools exist within the default repositories for most Linux distributions. The other tool to use is hddtemp - this will provide a simple temperature readout of your hard drive based on the S.M.A.R.T. Firstly, there are lmsensors which can poll most of the various sensors on your server and in this instance will provide you the temperature of your server’s CPU. There are tools in Linux you can use for monitoring temperatures.

Installing Im-sensors and Hddtemp For Temperature Monitoring This is a good indicator of the health of your server’s hardware and how it’s coping with the workload you are putting it under. While data centers keep the spaces housing their servers at consistent temperatures, the temperature of your server can alter depending on the workload on the server and the condition of the hardware.

An oft overlooked monitoring statistic for your server is the server’s running temperatures.
