The turbostat plugin reads CPU frequency and C-state residency on modern Intel turbo-capable processors.


Synopsis

None of the following option should be set manually This plugin automatically detects most optimal options

Only set values here if:

  • The module ask you to
  • You want to disable the collection of some data
  • Your (intel) CPU is not supported (yet) by the module
  • The module generate a lot of errors 'MSR offset 0x... read failed'

In the last two cases, please open a bug request
