Originally written by Thomas Schreck, this panel plugin shows information about the CPU governor and frequencies supported and used by your system. At the moment, changing any of these settings is not supported by this plugin but planned for future releases.


From the configuration dialog, which is available by right-clicking on the panel widget, select the CPU which you want to monitor in the panel. Instead of showing values for a single CPU, you can alternatively choose minimum, average or maximum, which might make more sense on a multi-core system. If your system is using the Intel pstate driver, the current maximum will be chosen by default, as this is what other monitoring applications like i7z show as the current real performance.

The remaining options on the configuration dialog let you customize the panel widget layout and what data is shown on the panel.

The overview window can be accessed by left-clicking on the panel plugin widget, or from the context menu, similar to the configuration dialog. It shows detailed information for every CPU (core).

The overview dialog:
