Functions

func GaugeMillisecond

func GaugeMillisecond(ctx context.Context, si64 *stats.Int64Measure, value int64, tagMutator ...tag.Mutator)

func IncrementInt64Counter

func IncrementInt64Counter(ctx context.Context, si64 *stats.Int64Measure, tagMutator ...tag.Mutator)

func Init

func Init(ctx context.Context, cfg Config, lg log.Logger)

Init initialises OpenCensus based async-telemetry processes and returns (i.e., it does not block).
