func GoPanicWrap ¶

func GoPanicWrap(ctx context.Context, wg *sync.WaitGroup, name string, body func(context.Context))

GoPanicWrap extends PanicWrap by running the body in a goroutine and synchronizing the goroutine exit with the WaitGroup. The body must respect cancellation of the Context.

func Link ¶

func Link(span tracer.Span, l *zap.Logger) *zap.Logger

Link connects a logger to a particular trace and span. DD APM should provide some additional functionality based on that.

func PanicWrap ¶

func PanicWrap(ctx context.Context, name string, body func(context.Context))

PanicWrap executes the body guarding for panics. If panic happens it emits a span with the error attached. This should trigger DD APM's Error Tracking to record the error.

func SpanResource ¶

func SpanResource(span Span, resource string)

func SpanTag ¶

func SpanTag(span Span, key string, value interface{})

func SpanType ¶

func SpanType(span Span, typ string)

func Start ¶

func Start(version string, l *zap.Logger)

Start boots the datadog tracer, run this once early in the startup sequence.

func Stop ¶

func Stop()

Stop shuts down the datadog tracer, defer this right after Start().

func Wrap ¶

func Wrap(ctx context.Context, log *zap.Logger, operation string, action func(context.Context, *zap.Logger, Span) error) error

Wrap executes action in the context of a span. Tags the span with the error if action returns one.
