need a little bit of help setting up a gorilla mux handler with telemetry

Davide Fastoso

Copy code

go
func myWonderfullHandler(h http.Handler) http.Handler {
	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
defer func() {
// SETTING UP initTRACE somehow 
}

Is it right

in general, this line should do the trick:

Copy code

r.Use(otelmux.Middleware("my-server"))

this is the import:

Copy code

"<http://go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux|go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux>"

thank u everybody you are so great! it is the example that has been working on my machine but instead of letting it print on my console i want to let it print on a remote signoz instance on the kubernetes. As i understand i should try to reach it and assign it with the method

WithEndpoint()

but when i pass the references to it http://collector.telemetry.svc.cluster.local:4317/ doesnt work

How did you come up with the above url?

Ankit Nayan

10/20/2021, 6:14 PM

above url means svc name is

collector

and namespace is

telemetry

. Is it so? If you used the helm chart and deployed it on namespace

platform

the address would be

<http://otel-collector.platform.svc.cluster.local:4317>

somebody else in my comp must have deployed , i dont have history of it. Thank you very much for explanation, so for to reach my endpoint up should i put as a

serviceNameKey.String("collector")

And as

WithEndpoint("<http://collector.telemetry.svc.cluster.local:4317/>")

Ankit Nayan

serviceNameKey

is the string that you want your application to be known by in UI...it has nothing to do with anything else

the service that I was talking about in the url is a kubernetes resource

Ankit Nayan

10/21/2021, 7:45 AM

like this https://github.com/SigNoz/signoz/blob/main/deploy/kubernetes/otel-collector/service.yaml#L4

Ankit Nayan

10/21/2021, 7:47 AM

I don't think the other person would have changed that..so ideally the url would be

Copy code

<http://otel-collector>.<namespace>.svc.cluster.local:4317

Ankit Nayan

10/21/2021, 7:47 AM

also try removing the trailing slash

Davide Fastoso

10/21/2021, 7:56 AM
