	// contains filtered or unexported fields
}

func NewDiskMeasurement 

func NewDiskMeasurement(start time.Time) *DiskMeasurement

NewDiskMeasurement returns a new populated DiskMeasurement

func (*DiskMeasurement) ToPoint 

func (m *DiskMeasurement) ToPoint(p *data.Point)

func (gm *GenericMeasurements) ToPoint(p *data.Point)

type GenericMetricsSimulator 

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

GenericMetricsSimulator provides a possibility to generate a configurable amount of metrics per host where other simulators have hardcoded metric set. This simulator also controls how long a host lives (hosts lifetime follows zipf distribution)

func (*GenericMetricsSimulator) Fields 

func (gms *GenericMetricsSimulator) Fields() map[string][]string

Fields returns a map of subsystems to metrics collected Since each host has different number of fields (we use zipf distribution to assign # fields) we search for the host with the max number of fields

func (GenericMetricsSimulator) Finished 

func (s GenericMetricsSimulator) Finished() bool

Finished tells whether we have simulated all the necessary points

func (*GenericMetricsSimulator) Headers 

func (gms *GenericMetricsSimulator) Headers() *common.GeneratedDataHeaders

func (*GenericMetricsSimulator) Next 

func (gms *GenericMetricsSimulator) Next(p *data.Point) bool

Next advances a Point to the next state in the generator.

func (GenericMetricsSimulator) TagTypes 

func (s GenericMetricsSimulator) TagTypes() []string

type GenericMetricsSimulatorConfig 

type GenericMetricsSimulatorConfig struct {
	*DevopsSimulatorConfig
}

func (*GenericMetricsSimulatorConfig) NewSimulator 

func (c *GenericMetricsSimulatorConfig) NewSimulator(interval time.Duration, limit uint64) common.Simulator

NewSimulator creates GenericMetricsSimulator for generic-devops use-case. Number of metrics assigned to each host follow zipf distribution. 50% of hosts is long lived and 50% has a liftspan that follows zipf distribution.

type Host 

type Host struct {
