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.
</para></note>
<para lang="en">When there is no CPU frequency scaling support in the system, the CPU Frequency Scaling Monitor only displays the current CPU frequency.</para>
<para lang="en">When CPU frequency scaling is supported in the system, the CPU Frequency Scaling Monitor 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.</para>
<para lang="en">By default the CPU Frequency Scaling Monitor 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 CPU Frequency Scaling Monitor see <xref linkend="cpufreq-applet-prefs"/>.</para>

instance of CPU Frequency Scaling Monitor for each CPU that you want to monitor if you are in a
