CPUPOWER-FREQUENCY-SET(1) cpupower Manual CPUPOWER-FREQUENCY-SET(1)NAME
cpupower frequency-set - A small tool which allows to modify cpufreq settings.
cpupower [ -c cpu ] frequency-set [options]
cpupower frequency-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scal-
ing_set_speed" all the time.
OPTIONS -d --min <FREQ>
new minimum CPU frequency the governor may select.
-u --max <FREQ>
new maximum CPU frequency the governor may select.
-g --governor <GOV>
new cpufreq governor.
-f --freq <FREQ>
specific frequency to be set. Requires userspace governor to be available and loaded.
modify all hardware-related CPUs at the same time
By default values are applied on all cores. How to modify single core configurations is described in the cpupower(1) manpage in the --cpu
The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter.
FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (fre-
quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).
On Linux kernels up to 2.6.29, the -r or --related parameter is ignored.

cpufreq-selector -- tool to set CPU frequency
cpufreq-selector [-c CPU] [-g GOV] [-f FREQ]
cpufreq-selector is a command-line tool for choosing CPU frequency settings.
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
-?, --help " 10 Show summary of options.
--cpu=NUMBER " 10 number of CPU to set. If omitted, zeroth CPU is implied.
--governor=GOV " 10 CPU governor to use, such as ``powersave'', ``performance''.
--freq=FREQ " 10 CPU frequency to use, in kHz.

so we frequently receive a lot of cpu related alerts. all types of checks have been created to keep an eye on the cpu but a lot of these checks make too much noise as the CPU is always being seen as high. the system and application owners say there's no issue with the cpu.
so now,... (6 Replies)
