Functions ¶
func Middleware ¶ added in v0.4.0
Middleware sets up a handler to start tracing the incoming requests. The service parameter should describe the name of the (virtual) server handling the request.
func OtelClientTrace ¶ added in v0.4.0
func OtelClientTrace(next http.RoundTripper) http.RoundTripper
OtelClientTrace adds tracing functionality to an http client (espressed as a roundtripper for api consistency)
func WithAttributes ¶
WithAttributes collects attributes into a attribute slice
Types ¶
type ClientTraceOption ¶
type ClientTraceOption func(*ClientTraceOptions)
ClientTraceOption
func WithClientTracer ¶
func WithClientTracer(tr trace.Tracer) ClientTraceOption
WithClientTracer sets a specific tracer to be uses
type ClientTraceOptions ¶
type ClientTraceOptions struct {
// contains filtered or unexported fields
}
ClientTraceOptions
type ClientTracer ¶
type ClientTracer interface {
StartSpan(ctx context.Context, spanName string, attrs []attribute.KeyValue, opts ...trace.SpanOption) (context.Context, trace.Span)
EndSpan(span trace.Span)
AnnotateWithClientTrace(ctx context.Context) context.Context
}
ClientTracer allows tracing of blaze services
func NewClientTracer ¶
func NewClientTracer(opts ...ClientTraceOption) ClientTracer
NewClientTracer creates a new tracer
type Option ¶ added in v0.4.0
type Option func(*config)
Option specifies instrumentation configuration options.
func WithPropagators ¶ added in v0.4.0
func WithPropagators(propagators propagation.TextMapPropagator) Option
WithPropagators specifies propagators to use for extracting information from the HTTP requests. If none are specified, global ones will be used.
func WithTracerProvider ¶ added in v0.4.0
func WithTracerProvider(provider oteltrace.TracerProvider) Option
WithTracerProvider specifies a tracer provider to use for creating a tracer. If none is specified, the global provider is used.
type RoundTripperFunc ¶ added in v0.4.0
The RoundTripperFunc type is an adapter to allow the use of ordinary functions as RoundTrippers. If f is a function with the appropriate signature, RountTripperFunc(f) is a RoundTripper that calls f.
type ServiceTraceOption ¶
type ServiceTraceOption func(*ServiceTraceOptions)
ServiceTraceOption
func WithInjectTracerFunction ¶ added in v0.4.0
func WithInjectTracerFunction(itf func(ctx context.Context) context.Context) ServiceTraceOption
WithInjectTracerFunction sets a specific inject tracer function
func WithTracer ¶
func WithTracer(tr trace.Tracer) ServiceTraceOption
WithTracer sets a specific tracer to be uses
func WithTracingMiddleware ¶ added in v0.4.0
func WithTracingMiddleware(tmw func(string) func(next http.Handler) http.Handler) ServiceTraceOption
WithTracingMiddleware sets a specific tracing middleware
type ServiceTraceOptions ¶
type ServiceTraceOptions struct {
// contains filtered or unexported fields
}
ServiceTraceOptions
type ServiceTracer ¶
type ServiceTracer interface {
InjectTracer(ctx context.Context) context.Context
TracingMiddleware(service string) func(next http.Handler) http.Handler
StartSpan(ctx context.Context, spanName string, attrs []attribute.KeyValue, opts ...trace.SpanOption) (context.Context, trace.Span)
EndSpan(span trace.Span)
}
ServiceTracer allows tracing of blaze services
func NewServiceTracer ¶
func NewServiceTracer(opts ...ServiceTraceOption) ServiceTracer
NewServiceTracer
