# Plugin to measure CPU frequency via cpufreq-info binary.
|
|
# This makes the plugin run on linux machines only.
|
|
# However the same goes for using sysfs directly.

# @remarks
|
|
# jo20061130 using cpufreq-info should simplify the whole thing
|
|
# jo20061202 tested on AMD K8 X2, intel Core 2 Duo
