Le but est de pouvoir récupérer les mèmes informations que sur le Gestionnaire de Tâches

wql sur root/CIMV2

Select * from Win32_Processor

instance of Win32_Processor

 show
{
	AddressWidth = 64;
	Architecture = 9;
	AssetTag = “To Be Filled By O.E.M.”;

	L3CacheSize = 8192;
	L3CacheSpeed = 0;

	LoadPercentage = 2;

	PowerManagementSupported = FALSE;
	ProcessorId = “BFEBFBFF000906E9”;
	ProcessorType = 3;
	Role = “CPU”;
	SecondLevelAddressTranslationExtensions = FALSE;
	SerialNumber = “To Be Filled By O.E.M.”;
	SocketDesignation = “U3E1”;

	ThreadCount = 8;

};

Avec la requette WMI ci dessous, on récupére CurrentClockSpeed et LoadPercentage.

LoadPercentage retourne l'utilisation du processeur a l'instant T.

CurrentClockSpeed la vitesse du CPU, mais n'a pas l'air de fluctuer comme on pourrait s'y attendre quand on regarde les performances dans le Gestionnaire de Tâches.

Select CurrentClockSpeed,CurrentVoltage,LoadPercentage from Win32_Processor

instance of Win32_Processor
{
	CurrentClockSpeed = 3600;
	CurrentVoltage = 10;
	DeviceID = “CPU0”;
	LoadPercentage = 6;
};
