Functions

func ExtractHTTPHeader

func ExtractHTTPHeader(ctx context.Context, headers http.Header) context.Context

func InitTracer

func InitTracer(ctx context.Context, cfg Config, resource *resource.Resource) (func(context.Context) error, error)

func InjectHTTPHeader

func InjectHTTPHeader(ctx context.Context, headers http.Header)

func ResetTracer

func ResetTracer()

func SetTracer

func SetTracer(name string)

SetTracer sets the tracer with the specified name. This function only takes effect on the first call.

func Tracer

func Tracer() trace.Tracer

Tracer returns the current tracer. If the tracer has not been set previously, nil pointer error.

Types

type Config

type Config struct {
	Mode                   Mode          `koanf:"mode"` // Operating mode for the metrics system
	HTTPCollectionEndpoint string        `koanf:"http_collection_endpoint"`
	GRPCCollectionEndpoint string        `koanf:"grpc_collection_endpoint"`
	BatchTimeout           time.Duration `koanf:"batch_timeout"`
	BatchSize              int           `koanf:"batch_size"`
	SSLMode                bool          `koanf:"ssl_mode"`
	SamplingRatio          float64       `koanf:"sampling_ratio"` // Sampling rate (0-1)
}

Config holds the quick-connect traces system configuration.

type Mode

type Mode string

Mode specifies the operational mode of the metrics system.
