data CPUHandle

The handle exported by this module

data TempHandle

The handle for themperature

data FreqHandle

The handle for cpu frequency

data NumaHandle

Numa aware version of CPUHandle

Constructors

NumaHandle

Fields

• numaCpus :: [String]
• numaHandle :: CPUHandle

getCPUHandle :: IO CPUHandle

Create an CPUHandle

getCPUPercent :: CPUHandle -> IO [Int]

Get the cpu usage in percent for each (virtual) cpu

getNumaPercent :: NumaHandle -> IO [Int]

Read node information

getCPUTemp :: TempHandle -> IO Int

get current CPU temperature

getCPUMaxScalingFreq :: FreqHandle -> IO Float

This function returns a frequency according the ScalingType of the handle.

The returned valued will be the max of all (virtual) proceessors on the system.

data ScalingType

Which values should be returned by getCPUFreq

Constructors

ScalingMax

Use the maximum frequencie allowed

ScalingCur

Use the current frequencie used

ScalingNone

Don't open any files for scaling type

getNumaHandles :: IO [NumaHandle]

Get the Numa aware handle

guessThermalZone :: IO (Maybe String)

Tries to guess the thermal zone based on type

getThermalZone :: String -> IO TempHandle

Get the CPUs thermal zone

getThermalZones :: IO [TempHandle]

Get the CPUs thermal zones, will be same order as numa nodes (hopefully)

getFreqHandle :: ScalingType -> IO FreqHandle

Get a frequency handle by type

getFreqNuma :: ScalingType -> NumaHandle -> IO FreqHandle

Get a frequency handle limited to the cpus the numa handle uses
