This is a Gnome shell extension which aims to indicate the usage of system resources on a GNU/Linux OS.
It displays a list of icons as indicator in the top bar of a Gnome shell.
When you use a piece of application on your computer, sometimes it does not clear what it is doing, you only see that the requested action has not completed. For example you do not know for sure if an misbehaving application is waiting for the network or doing CPU heavy computation. This extension can help with this by displaying resources using symbolic icons and indicate their usage by color. Resource usage color range starts from white (low usage) to red (high usage).
Besides the above, the detailed view can show you which processes or directories are responsible for the high resource utilization.
No clicks or key presses needed, just take a look at the top of the screen when an application misbehaves.
The following applications need to be installed:
- zip
- rake
Project can be built with Rake (http://rake.rubyforge.org/). To install Rake, first you need RubyGems package manager which is available via the own package manager of the OS. Once you have that, issue the following command:
gem install rake
Then rake build command will make the “build/System_Monitor@bghome.gmail.com-[version].zip” for you.
To remove all generated files, use the rake cleanup command.
Extensions can be installed per-user in ~/.local/share/gnome-shell/extensions, or system wide in /usr/share/gnome-shell/extensions and /usr/local/share/gnome-shell/extensions. You can simply extract the content of the zip archive to the proper location or use Gnome Tweak tool.
Also don't forget to install the dependencies. You can find distribution specific instructions on the Installation wiki page.
