Summary
github.com/micro/go-plugins is very huge, and contains a log of package dependency. This repository is only a zipkin opentracing wapper for go-micro project, so the usage of this module is more simple and lightweight.
Usage
package main
import (
"github.com/micro/go-micro"
"github.com/x-punch/micro-zipkin"
)
func main() {
zipkin.SetGlobalTracer("test.srv", ":80", "https://zipkin/api/v1/spans")
service := micro.NewService(micro.WrapHandler(zipkin.NewHandlerWrapper()))
service.Init(micro.Name("test.srv"), micro.Address(":80"))
if err := service.Run(); err != nil {
panic("Failed to run service: " + err.Error())
}
}

Functions ¶
func NewHandlerWrapper ¶
func NewHandlerWrapper() server.HandlerWrapper
NewHandlerWrapper accepts an opentracing Tracer and returns a Handler Wrapper
func SetGlobalTracer ¶
SetGlobalTracer sets the [singleton] opentracing.Tracer returned by GlobalTracer(). Those who use GlobalTracer (rather than directly manage an opentracing.Tracer instance) should call SetGlobalTracer as early as possible in main(), prior to calling the `StartSpan` global func below. Prior to calling `SetGlobalTracer`, any Spans started via the `StartSpan` (etc) globals are noops.
func StartSpanFromContext ¶
func StartSpanFromContext(ctx context.Context, name string, opts ...opentracing.StartSpanOption) (context.Context, opentracing.Span, error)
StartSpanFromContext returns a new span with the given operation name and options. If a span is found in the context, it will be used as the parent of the resulting span.
