Psensor is a GTK+ (Widget Toolkit for creating Graphical User Interface) based application software. It is one the simplest application to monitor hardware temperature and plot Real Time graph from the obtained data for quick review.

Linux Hardware Temperature Monitoring

Psensor – Linux Hardware Temperature Monitoring

Features of Psensor

  1. Show Temperature of motherboard, CPU, GPU (Nvidia), Hard Disk Drives.
  2. Show CPU fan speed.
  3. Psensor is capable of showing remote server Temperature and Fan Speed.
  4. Show CPU usages, as well.
  5. Infact Psensor will detect any supported Hardware and report the Temperature as text and over graph, automatically.
  6. All the temperatures are plotted in one graph.
  7. Alarms and Alerts ensures you don’t miss a critical System Hardware Temperature and Fan Speed related issues.
  8. Easy to Configure. Easy to use.

Dependencies

  1. lm-sensor and hddtemp: : Psensor depends upon these two packages to get the reports about temperature and fan speed.
  2. psensor-server : It is an optional package, which is required if you want to gather information about Remote Server Temperature and Fan Speed.

Installation of Psensor in Linux

1. As I said above that Psensor program depends on lm-sensor and hddtemp package and these two packages must installed on the system in order to install Psensor.

Both these two packages are available in the official repository of most of the standard Linux distributions, but in RedHat/CentOS based systems, you need to install and enable epel-release repository to get these packages.

On Debian, Ubuntu and Mint

# apt-get install lm-sensors hddtemp

On RedHat, CentOS and Fedora

# yum install epel-release # yum install lm_sensors lm_sensors-devel hddtemp

Note: If you are using Fedora 22, replace yum with dnf in above command.


2. Once these two dependencies installed on the system, you can install Psensor on Debian alike systems using following commands.

# apt-get install psensor

Unfortunately, on RedHat alike systems, Psensor isn’t available from the default system repository, and you need to compile it from source as shown below.

# yum install gcc gtk3-devel GConf2-devel cppcheck libatasmart-devel libcurl-devel json-c-devel libmicrohttpd-devel help2man libnotify-devel libgtop2-devel make 

Next, download the most recent stable Psensor (i.e version 1.1.3) source tarball and compile it using following commands.

# wget http://wpitchoune.net/psensor/files/psensor-1.1.3.tar.gz # tar zxvf psensor-1.1.3.tar.gz # cd psensor-1.1.3/ # ./configure # make # make install

3. Install Psensor Server – optional. It is required only if you want to see the temperature and fan speed of remote server.

# apt-get install psensor-server

Note: That the Psensor Server package is only available under Debian alike systems, there isn’t any binary or source packages available for RedHat systems.

Testing and Usage of Psensor

4. It is optional but suggestive step you should follow. Run sensors-detect, as root to diagnose the hardware’s by sensors. Every Time Type the default option ‘Yes’, until you know what you are doing.

# sensors-detect
Detect Sensors

Detect Sensors

5. Again Optional but suggestive setup you should follow. Run sensors, as root to display the temperature of various Hardware Devices. All these Data will be used for Psensor.

# sensors
Check Temperature Hardware

6. Run Psensor, from the desktop Application Menu to get the graphical view.

Customize Psensor

7. Go to Menu Psensor ? Preferences ? Interface. From here, you can have options for Interface related customization, Temperature Unit and Sensor table Position.

8. Under Menu Psensor ? Preferences ? Startup. From here, you can configure Launch/Hide at Startup and Restore Window Position and Size.

Control Psensor

9. Under the Hood Graph (Psensor ? Preferences ? Graph), you may configure Foreground/Background Color, Monitoring Duration, Update Interval, etc.

10. You may configure Sensors Settings under (Psensor ? Preferences ? Sensors).

11. The last tab (Psensor ? Preferences ? Providers) provides you with Enable/Disable configuration for all the sensors.

Conclusion

Psensor is a very useful tool which lets you see those gray areas of system monitoring which is often overlooked upon i.e., Hardware temperature monitoring. A over heating Hardware may damage that particular hardware, other hardware in the surrounding or may crash the whole system.

No, I am not thinking from financial perspective. Think of the value of Data that might loose and the cost and time it will take to build the system again. Hence it is always a good idea to have a tool like Psensor beside ourselves to avoid any such risk.

Installation on Debian alike system is pretty simple. For CentOS and alike System, installation is a bit tricky.
