Functions

func ExtractSampledTraceID

func ExtractSampledTraceID(ctx context.Context) (string, bool)

ExtractSampledTraceID works like ExtractTraceID but the returned bool is only true if the returned trace id is sampled.

func ExtractTraceID

func ExtractTraceID(ctx context.Context) (string, bool)

ExtractTraceID extracts the trace id, if any from the context.

func ExtractTraceSpanID

func ExtractTraceSpanID(ctx context.Context) (string, string, bool)

ExtractTraceSpanID extracts the trace id, span id if any from the context.

func NewFromEnv

func NewFromEnv(serviceName string, options ...jaegercfg.Option) (io.Closer, error)

NewFromEnv is a convenience function to allow tracing configuration via environment variables

Tracing will be enabled if one (or more) of the following environment variables is used to configure trace reporting: - JAEGER_AGENT_HOST - JAEGER_SAMPLER_MANAGER_HOST_PORT
