README

monkit-zipkin

A plugin for http://github.com/spacemonkeygo/monkit that supports Zipkin.

See the docs at http://godoc.org/gopkg.in/spacemonkeygo/monkit-zipkin.v2

Example usage

Your main method gets set up something like this:

age main

rt (
"net/http"

"gopkg.in/spacemonkeygo/monkit-zipkin.v2"
"gopkg.in/spacemonkeygo/monkit.v2"
"gopkg.in/spacemonkeygo/monkit.v2/environment"
"gopkg.in/spacemonkeygo/monkit.v2/present"


 main() {
environment.Register(monkit.Default)
go http.ListenAndServe("localhost:9000", present.HTTP(monkit.Default))
collector, err := zipkin.NewScribeCollector("zipkin.whatever:9042")
if err != nil {
    panic(err)
}
zipkin.RegisterZipkin(monkit.Default, collector, zipkin.Options{
    Fraction: 1})

...

Once you've done that, you need to make sure your HTTP handlers pull Zipkin Context info from the Request. That's easy to do with zipkin.ContextWrapper.

 HandleRequest(ctx context.Context, w http.ResponseWriter,
*http.Request) {
fer mon.Task()(&ctx)(nil)

. whatever


 DoTheThing(ctx context.Context) (err error) {
fer mon.Task()(&ctx)(&err)
turn http.Serve(listener, zipkin.ContextWrapper(
zipkin.TraceHandler(zipkin.ContextHTTPHandlerFunc(HandleRequest))))

Last, your outbound HTTP requests need to pass through Context info:

 MakeRequest(ctx context.Context) (err error) {
fer mon.Task()(&ctx)(&err)
q, err := http.NewRequest(...)
 err != nil {
return err

sp, err := zipkin.TraceRequest(ctx, http.DefaultClient, req)
.
