Instana instrumentation for gorilla mux
This module contains middleware to instrument HTTP services written with github.com/gorilla/mux.
Installation
To add the module to your go.mod file run the following command in your project directory:
$ go get github.com/instana/go-sensor/instrumentation/instamux
Usage
// Create a sensor
sensor := instana.NewSensor("my-web-server")
// Create router
r := mux.NewRouter()
// Instrument your router by adding a middleware
instamux.AddMiddleware(sensor, r)
// Define handlers
r.HandleFunc("/foo", func(writer http.ResponseWriter, request *http.Request) {})
...

Overview ¶
Example ¶
This example shows how to instrument an HTTP server that uses github.com/gorilla/mux with Instana
package main
import (
"log"
"net/http"
"github.com/gorilla/mux"
instana "github.com/instana/go-sensor"
"github.com/instana/go-sensor/instrumentation/instamux"
)
func main() {
sensor := instana.NewSensor("my-web-server")
r := mux.NewRouter()
// Add an instrumentation middleware to the router. This middleware will be applied to all handlers
// registered with this instance.
instamux.AddMiddleware(sensor, r)
// Use mux.Router to register request handlers as usual
r.HandleFunc("/foo", func(w http.ResponseWriter, req *http.Request) {
// ...
})
if err := http.ListenAndServe(":0", nil); err != nil {
log.Fatalf("failed to start server: %s", err)
}
}
