How to install Psensor in Linux

Installation of Psensor in Linux

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

Features

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

Dependencies

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

To Install Psensor

Before installing Psensor, install lm-sensor and hddtemp package on your system.
In RedHat/CentOS based systems, you need to install and enable epel-release repository to get these packages.

On Debian based distributions

root@linuxhelp:~# apt-get install lm-sensors hddtemp psensor -y

To Install Psensor Server

On Debian based distributions
Run the following command to Install Psensor Server . It is required only if you want to see the temperature and fan speed of remote server.

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

On RedHat based distributions
Download all the depedency packages before installing Psensor Server

# 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 source tarball and compile it using following commands.

# wget http://wpitchoune.net/psensor/files/psensor-1.1.5.tar.gz
# tar zxvf psensor-1.1.5.tar.gz
# cd psensor-1.1.5/
# ./configure
# make
# make install

To test the Usage of Psensor

Run sensors-detect as root to diagnose the hardwares.

root@linuxhelp:~# sensors-detect
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# System: VMware, Inc. VMware Virtual Platform [None]
# Board: Intel Corporation 440BX Desktop Reference Platform

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you' re doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
.
.
.
To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)

Unloading cpuid... OK

Run sensors as root to display the temperature of various Hardware Devices.

root@linuxhelp:~# sensors
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +100.0° C (high = +100.0° C, crit = +100.0° C)
Core 0: +100.0° C (high = +100.0° C, crit = +100.0° C)

Run Psensor from the desktop Application menu to get the graphical view.

Select all the Sensors to plot graph and also you may notice the color codes.

To Customize Psensor

Go to Psensor &rarr Preferences &rarr Interface. Here, you have options for Interface customization.

Select startup tab. Here, you can configure Launch/Hide at Startup and Restore Window Position and Size.

Choose Graph tab to configure Foreground/Background Color, Monitoring Duration, Update Interval, etc.

Open Sensors tab to configure sensors logging options.

Select providers tab to configure the hardware options.

Then go to Psensor &rarr Edit Sensor Preferences to edit the graph.
