EntityTypeGeneratorFunc generates an entity type.

type FetchFunc ¶

type FetchFunc func(groupLabel, entityID string, groups RawGroups) (FetchedValue, error)

FetchFunc fetches values or values from raw metric groups. Return FetchedValues if you want to prototype metrics.

func FromRaw(metricKey string) FetchFunc

func Transform(fetchFunc FetchFunc, transformFunc TransformFunc) FetchFunc

type FetchedValue ¶

type FetchedValue interface{}

FetchedValue is just any value from an already fetched metric.

type FetchedValues ¶

type FetchedValues map[string]FetchedValue

FetchedValues is a map of FetchedValue indexed by metric name.

type GuessFunc ¶

type GuessFunc func(clusterName, groupLabel, entityID string, groups RawGroups) (string, error)

GuessFunc guesses from data.

type MetricSetManipulator ¶

type MetricSetManipulator func(ms metric.MetricSet, entity sdk.Entity, clusterName string) error

MetricSetManipulator manipulates the MetricSet for a given entity and clusterName

type PopulateFunc ¶

type PopulateFunc func(RawGroups, SpecGroups) (bool, []error)

PopulateFunc populates raw metric groups using your specs

type RawMetrics ¶

type RawMetrics map[string]RawValue

RawMetrics is a map of RawValue indexed by metric name.

type RawValue ¶

type RawValue interface{}

RawValue is just any value from a raw metric.

type Spec ¶

type Spec struct {
	Name      string
	ValueFunc FetchFunc
	Type      sdk.SourceType
	Optional  bool
}

Spec is a metric specification.

type SpecGroup ¶

type SpecGroup struct {
	IDGenerator   EntityIDGeneratorFunc

SpecGroup represents a bunch of specs that share logic.

type SpecGroups ¶

type SpecGroups map[string]SpecGroup

SpecGroups is a map of groups indexed by group name.

type TransformFunc ¶

type TransformFunc func(FetchedValue) (FetchedValue, error)

TransformFunc transforms a FetchedValue.
