The  provides a convenient way to monitor the CPU Frequency Scaling for each CPU.
To add  to a panel, right-click on the panel to open the panel popup menu, then choose
Add to PanelCPU Frequency Scaling Monitor.
Unfortunately, CPU frequency scaling can currently only be monitored on
Linux machines that have support in the kernel. It can however, support the
several generations of frequency scaling interfaces in the kernel.
When there is no CPU frequency scaling support in the system, the  only displays the current CPU frequency.When CPU frequency scaling is supported in the system, the  displays the CPU icon with a progress bar. The state of the progress bar represents the current CPU frequency with respect to the maximum frequency.By default the  displays the current CPU frequency as a value
in Hertz (the standard measure of frequency), but can be configured to
display a percentage instead. For more information on how to configure  see .Each instance of  can monitor only one CPU. You must start an
instance of  for each CPU that you want to monitor if you are in a
multiprocessor (SMP) system.
