New relic integration with go : I am unable to monitor my go project with new relic

[urvesh-educloud]

I am unable to monitor my go project with the new relic

I am able to monitor using JAVA

I have follows the documentation steps: https://docs.newrelic.com/docs/apm/agents/go-agent/installation/install-new-relic-go/

1. From github.com/newrelic/go-agent, use your preferred process; for example:
   bash command go get github.com/newrelic/go-agent/v3/newrelic

2. Import the github.com/newrelic/go-agent/v3/newrelic package in your application.
   import github.com/newrelic/go-agent/v3/newrelic

3. Initialize the Go agent by adding the following in the main function or in an init block:

   app, err := newrelic.NewApplication(
       newrelic.ConfigAppName("Your Application Name"),
       newrelic.ConfigLicense("YOUR_NEW_RELIC_LICENSE_KEY")
   )
   

NOTE: I have follows all the trouble shooting as well.

main.go

package main

import (
	"fmt"
	"io"
	"net/http"

	"github.com/newrelic/go-agent/v3/newrelic"
)

var newrelicApp *newrelic.Application

func main() {
	app, err := newrelic.NewApplication(
		newrelic.ConfigAppName("MyAppMain"),
		newrelic.ConfigLicense("YOUR_NEW_RELIC_LICENSE_KEY"),
		newrelic.ConfigAppLogForwardingEnabled(true),
	)
	if err != nil {
		fmt.Printf("error is " + err.Error())
	} else {
		newrelicApp = app
		http.HandleFunc(newrelic.WrapHandleFunc(app, "/test", customEvent))
	}
}

func customEvent(w http.ResponseWriter, req *http.Request) {
	io.WriteString(w, "recording a custom event")

	newrelicApp.RecordCustomEvent("MyAppMainEvent", map[string]interface{}{
		"text":      "Hello VP",
		"env":       "go_local",
		"alertType": "error",
		"priority":  "Critical",
		"source":    "MyAppMain",
	})
}

Take a look at this example code and just double check that your implementation is following best practices: https://github.com/newrelic/go-agent/blob/master/v3/examples/server/main.go

If you're still having trouble let us know

Hi @iamemilio,
How can I execute this?
Can you provide the example so I can refer?
I want to create the app as well as the event. (as shown in the example) when I run the go project using "go run main.go"

When you wrap an http handler with new relic, we pass a transaction into the context. You should use that transaction to call the methods of the go agent application. To run this, first do go mod init, then go mod tidy, and finally go run main.go.

package main

import (
	"fmt"
	"io"
	"net/http"
	"os"

	"github.com/newrelic/go-agent/v3/newrelic"
)

func customEvent(w http.ResponseWriter, r *http.Request) {
	txn := newrelic.FromContext(r.Context())

	io.WriteString(w, "recording a custom event")

	txn.Application().RecordCustomEvent("MyAppMainEvent", map[string]interface{}{
		"text":      "Hello VP",
		"env":       "go_local",
		"alertType": "error",
		"priority":  "Critical",
		"source":    "MyAppMain",
	})
}

func main() {
	app, err := newrelic.NewApplication(
		newrelic.ConfigAppName("MyAppMain"),
		newrelic.ConfigLicense("YOUR_NEW_RELIC_LICENSE_KEY"),
		newrelic.ConfigAppLogForwardingEnabled(true),
	)
	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}

	
	http.HandleFunc(newrelic.WrapHandleFunc(app, "/custom_event", customEvent))
	http.ListenAndServe(":8000", nil)
}
