NAME

cpuspeed - Plugin to monitor CPU speed

APPLICABLE SYSTEMS

Linux systems with a working CPU speed governor/stats kernel module that can be accessed through the /sys filesystem.

CONFIGURATION

None needed by default.

You can set one environment variable to modify the plugins behaviour:

  [cpuspeed]
     env.scaleto100 1

Show the frequency as a percentage instead of absolute frequency. If set the plugin sets up a CDEF to change the speed in Hz to percent.

If you set or unset this the whole time series will be shown in the same way, either as Hz or percent (as the graphs are updated).

INTERPRETATION

The plugin shows the average CPU speed in the measurement period as represented by /sys/devices/system/cpu/*/cpufreq/stats/time_in_state.

This is a counter plugin and represents the average. Many cpuspeed plugins reports the "instant" CPU speed at the time the plugin runs. This is not representative for this metric.

BUGS

Nah.
