Cpu CLOCK graph

[Juniorr]

Is there a way I can monitor the CLOCK of my CPU with a graph? Like http://www.cmg.org/measureit/issues/mit31/m_31_2b.gif

That image is just an idea, any graph monitor would be nice, it must record the last hours no matter how much time it's on.

My choice is Psensor...

[Juniorr]

Oh, just realised, I need a CPU clock monitor, not a usage one.

each core functions independently, you can get the current frequencies with
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq
with the 3.10 kernel on some newer Intel CPUs it is
cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq (requires root, but you can chmod it to 444 to bypass that)
not sure how to make a graph but that can be used to get the base info, you will probably need the max frequency
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq

divide numbers by 1000 to convert to MHz divide by 1000 again to get GHz

Those directories doesn't exist. Just adding to this thread, aside from Jupiter (discontinued), is there a way of setting the cpu frequency to performance? I want to switch to Linux but my frames per second drop on some Valve Source Games, like Team Fortress 2, for example.

they should exist, one for every core

in xubuntu i use some genmon applets to control/monitor it

https://github.com/GM-Script-Writer-...pu-freq-plugin
if you call the script like this it should do what you want
sudo cpu-freq-plugin 0 --set
it should be able to set it on any DE

[Juniorr]

Should it be?

How is you bios configured, for example on a AMD system you would need cool n quiet enabled
overclocking can have the same effect

[Doug S]

If those directories don't exist on your system, then you do not have CPU frequency scaling, either because of a BIOS setting (as pq... mentioned) or because your CPU does not support it. In that case your CPU will already be in "performance" mode.

From an earlier posting:

each core functions independently, you can get the current frequencies with
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq
with the 3.10 kernel on some newer Intel CPUs it is
cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq

It does not have to be 13.10. And there can be incorrect information displayed as to current CPU frequency for at least some intel CPU's and some motherboards. They actually don't function independently. The only way to know for certain is to use turbostat.

I always had Cool and Quiet disabled on my BIOS, now that I enabled it that directory appears.
I'm just not sure how it affects the overall result since I believe the BIOS commands it all.

I also had "indicator-cpufreq" installed and it falied to load. Now (with QaQ enabled) it loads fine and give's me options to

Conservative
OnDemand
PowerSave
Performance
