System Monitor Indicator comes with options to display CPU load, memory usage, and other system stats, but currently does not include an option to display temperature (of the CPU, HDD, SSD, GPU, etc.).

enter image description here

There seems to be functionality built in for adding additional sensors by applying a command (by clicking "New"). However, I don't know how, and I cannot find any documentation that describes this feature.

My system is set up to report temperature as so:

user@host:~$ sensors
Adapter: Virtual device
temp1:        +27.8°C  (crit = +106.0°C)
temp2:        +29.8°C  (crit = +106.0°C)

Adapter: ISA adapter
Physical id 0:  +79.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +79.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +77.0°C  (high = +87.0°C, crit = +105.0°C)

Adapter: Virtual device
temp1:        +79.0°C  

This question refers to the package indicator-sysmonitor version 0.4.3 from 13.04 raring, although currently I am running it on a 13.10 saucy installation as it has not yet been updated in the ppa:


  • you can either wait for the indicator-sysmonitor or compile it from the source on launchpad.

  • I don't understand this comment. How would compiling the application myself add functionality to show temperature?

System Monitor Indicator is quite simple / flexible. You can add basically any script as custom sensor. The output it produces will then appear where you put its placeholder. I am using this to extract information from the output of sensors like this:

sensors | grep temp1 | awk '{print $2}' | sed 's/+//' 

to exctract the temperature or

sensors | grep fan1 | awk '{print $2}'

to extract the fan speed.

Just click on New, enter a name and a description and the respective lines from above under Command as shown here:

PS: After upgrading from Ubuntu 12.04 to 14.04 the tool seemed to have problems to read the configuration file, resulting in a crash when I tried to add sensors. Removing .indicator-sysmonitor.json from my home directory fixed this.

    Nice - I used sensors | grep "Core 1" | awk '{print $3}' as it can work differently on different hardware.

  • how does this works on "System Load Indicator" 0.4 ; I can't see a add menu with a command enter field.

  • System Load Indicator is a different application. This question is about github.com/fossfreedom/indicator-sysmonitor Nov 4, 2016 at 7:42
  • System monitor indicator is an awesome tool. Jan 6, 2021 at 0:02

There's an indicator for the temperature in this ppa:

sudo add-apt-repository ppa:alexmurray/indicator-sensors
sudo apt-get update
sudo apt-get install indicator-sensors

It’s already updated with packages for saucy, although I haven't tried it myself since I'm still using 13.04. You can then launch it from the dash or from the command-line and configure to show different sensors and set up alarms.

  • Thanks. I can recommend this indicator to anybody who's interested in temperature monitoring (in 13.10). However, I am still interested in answers to how to get temperature support in indicator-sysmonitor as well.

Perhaps look at what indicator-sensors does to get temperature information and put that into a shell script.

Then install indicator-sysmonitor and add your script to that.


As said here you have:

system-monitor GNOME Shell extension




sudo apt install psensor

as of now System Monitor Indicator can't show cpu temperature. Here is the answer from the author https://answers.launchpad.net/indicator-sysmonitor/+question/238748

  • There is no answer given at the link you provided, as far as I can see?

  • you right, but it was there yesterday. searching through the site, i belive it still does not support such feature now. Nov 14, 2013 at 16:11
