Method: LinuxStat::CPU.min_freq

Defined in:

lib/linux_stat/cpu.rb

.min_freq ⇒ Object

Returns a Hash with max core frequencies corresponding to the CPUs.

For example:

LinuxStat::CPU.min_freq

=> {"cpu0"=>2000000, "cpu1"=>2000000, "cpu2"=>2000000, "cpu3"=>2000000}

If the information isn’t available, it will return an empty Hash.
