Functions

func AddNewTagKey

func AddNewTagKey(views []*view.View, key *tag.Key) []*view.View

AddNewTagKey adds new tag keys to existing view

func AddTagKeyToCtx

func AddTagKeyToCtx(ctx context.Context, key tag.Key, value string) context.Context

AddTagKeyToCtx assigns opencensus tag key value to context

func GetTraceSamplingRate

func GetTraceSamplingRate(rate string) float64

GetTraceSamplingRate parses the given rate and returns the parsed rate

func NewMeasureView

func NewMeasureView(measure stats.Measure, keys []tag.Key, aggregation *view.Aggregation) *view.View

NewMeasureView creates opencensus View instance using stats.Measure

func WithTags

func WithTags(opts ...interface{}) []tag.Mutator

WithTags converts tag key and value pairs to tag.Mutator array. WithTags(key1, value1, key2, value2) returns []tag.Mutator{tag.Upsert(key1, value1), tag.Upsert(key2, value2)}
