Functions

func ConvertEvent 

func ConvertEvent(e stats.Event) *dogstatsd.Event

ConvertEvent converts a stats event to a statsd (datadog) event.

func NewTracer 

func NewTracer(opts ...TracerOption) opentracing.Tracer

NewTracer returns a new tracer.

It defaults to the service environment as named by the `SERVICE_ENV` environment variable. It defaults the sample rate to the sample rate as returned by the configuration.

func UseProfiler added in v1.20210103.1 

func UseProfiler(cfg Config) bool

UseProfiler returns if profiling is enabled and the profiler address is configured.

It should be used to gate if you should create a profiler with `profiler.Start`.

func UseTracing 

func UseTracing(cfg Config) bool

UseTracing returns if tracing is enabled and the trace address is configured.

It should be used to gate if you should create tracers with `NewTracer`.
