Types

type CounterInstanceVerify

type CounterInstanceVerify func(string) bool

CounterInstanceVerify is a callback function called by GetCounterSet for each instance of the counter. Implementation should return true if that instance should be included, false otherwise

type PdhCounterSet

type PdhCounterSet struct {
	// contains filtered or unexported fields
}

PdhCounterSet is the object which represents a pdh counter set.

func GetCounterSet

func GetCounterSet(className string, counterName string, instanceName string, verifyfn CounterInstanceVerify) (*PdhCounterSet, error)

GetCounterSet returns an initialized PDH counter set.

func (*PdhCounterSet) Close

func (p *PdhCounterSet) Close()

Close closes the query handle, freeing the underlying windows resources.

func (*PdhCounterSet) GetAllValues

func (p *PdhCounterSet) GetAllValues() (values map[string]float64, err error)

GetAllValues returns the data associated with each instance in a query.

func (*PdhCounterSet) GetSingleValue

func (p *PdhCounterSet) GetSingleValue() (val float64, err error)

GetSingleValue returns the data associated with a single-value counter
