Types

type EntityMetric

type EntityMetric struct {
	Entity types.ManagedObjectReference

	SampleInfo []types.PerfSampleInfo
	Value      []MetricSeries
}

EntityMetric contains the same data as types.PerfEntityMetric, but with MetricSeries type for the Value field.

func (*EntityMetric) SampleInfoCSV

func (m *EntityMetric) SampleInfoCSV() string

SampleInfoCSV converts the SampleInfo field to a CSV string

type IntervalList

type IntervalList []types.PerfInterval

IntervalList wraps []types.PerfInterval.

func (IntervalList) Enabled

func (l IntervalList) Enabled() map[int32][]string

Enabled returns a map with Level as the key and enabled PerfInterval.Name(s) as the value.

type Manager

type Manager struct {
	object.Common

	Sort bool
	// contains filtered or unexported fields
}

Manager wraps mo.PerformanceManager.

func NewManager

func NewManager(client *vim25.Client) *Manager

NewManager creates a new Manager instance.

func (*Manager) AvailableMetric

func (m *Manager) AvailableMetric(ctx context.Context, entity types.ManagedObjectReference, interval int32) (MetricList, error)

AvailableMetric wraps the QueryAvailablePerfMetric method. The MetricList is sorted by PerfCounterInfo.GroupInfo.Key if Manager.Sort == true.

func (*Manager) CounterInfo

func (m *Manager) CounterInfo(ctx context.Context) ([]types.PerfCounterInfo, error)

CounterInfo gets the PerformanceManager.PerfCounter property. The property value is only collected once, subsequent calls return the cached value.

func (*Manager) CounterInfoByKey

func (m *Manager) CounterInfoByKey(ctx context.Context) (map[int32]*types.PerfCounterInfo, error)

CounterInfoByKey converts the PerformanceManager.PerfCounter property to a map, where key is types.PerfCounterInfo.Key.

func (*Manager) CounterInfoByName

func (m *Manager) CounterInfoByName(ctx context.Context) (map[string]*types.PerfCounterInfo, error)

CounterInfoByName converts the PerformanceManager.PerfCounter property to a map, where key is types.PerfCounterInfo.Name().

func (*Manager) HistoricalInterval

func (m *Manager) HistoricalInterval(ctx context.Context) (IntervalList, error)

HistoricalInterval gets the PerformanceManager.HistoricalInterval property and wraps as an IntervalList.

func (*Manager) ProviderSummary

func (m *Manager) ProviderSummary(ctx context.Context, entity types.ManagedObjectReference) (*types.PerfProviderSummary, error)

ProviderSummary wraps the QueryPerfProviderSummary method, caching the value based on entity.Type.

func (*Manager) Query

Query wraps the QueryPerf method.

func (*Manager) SampleByName

func (m *Manager) SampleByName(ctx context.Context, spec types.PerfQuerySpec, metrics []string, entity []types.ManagedObjectReference) ([]types.BasePerfEntityMetricBase, error)

SampleByName uses the spec param as a template, constructing a []types.PerfQuerySpec for the given metrics and entities and invoking the Query method. The spec template can specify instances using the MetricId.Instance field, by default all instances are collected. The spec template MaxSample defaults to 1. If the spec template IntervalId is a historical interval and StartTime is not specified, the StartTime is set to the current time - (IntervalId * MaxSample).

func (*Manager) ToMetricSeries

func (m *Manager) ToMetricSeries(ctx context.Context, series []types.BasePerfEntityMetricBase) ([]EntityMetric, error)

ToMetricSeries converts []BasePerfEntityMetricBase to []EntityMetric

type MetricList

type MetricList []types.PerfMetricId

MetricList wraps []types.PerfMetricId

func (MetricList) ByKey

func (l MetricList) ByKey() map[int32][]*types.PerfMetricId

ByKey converts MetricList to map, where key is types.PerfMetricId.CounterId / types.PerfCounterInfo.Key

type MetricSeries

type MetricSeries struct {
	Name string

	Instance string
	Value    []int64
	// contains filtered or unexported fields
}

MetricSeries contains the same data as types.PerfMetricIntSeries, but with the CounterId converted to Name.

func (*MetricSeries) Format

func (s *MetricSeries) Format(val int64) string

func (*MetricSeries) ValueCSV

func (s *MetricSeries) ValueCSV() string

ValueCSV converts the Value field to a CSV string
