indicator-sysmonitor – Ubuntu application indicator to show system information

A useful simple application indicator to show various system information such as:

  • File system disk space usage
  • Network activity
  • Memory usage
  • CPU usage
  • Swap space usage

It also has a very useful “Run what you want and display the result” usage – I used it here to show if the internet is up or down – for example, your router could be working fine, but your ISP has pulled the plug on you!

If you come up with any interesting scripts, drop a comment with a link and share with others the fruit of your labours 🙂

The original maintainer has not released a version since Ubuntu Raring and for later Ubuntu versions.  No code commits in the launchpad PPA has been made since first quarter 2013.  I presume the project has been mothballed.

Thus I have forked the project, fixed a few bugs and made it available for 14.04 Trusty users.  Feel free to check out the code on GitHub and help out with the maintenance. N.B. I don’t know how to use bzr on Launchpad so sorry in advance to the maintainer … if you want the code back grab it!

I’ve reproduced the answer from my Ask Ubuntu article here – attribution is obviously with Stack Exchange since that’s where the answer was written.

It requires an indicator from my PPA together with a custom ping test script:

sudo add-apt-repository ppa:fossfreedom/indicator-sysmonitor
sudo apt-get update
sudo apt-get install indicator-sysmonitor
mkdir -p ~/scripts && cd ~/scripts



Copy and paste the code below into the new file and save & close.

Give the file execute permission:

chmod +x

Start the indicator

indicator-sysmonitor &

Then in the indicator-preferences click New:
