Using New Relic with a Go web application

I stumbled into a great middleware named gorelic.

It's too easy to start using it and you get useful information about your app.

package main

import (
    "github.com/labstack/echo"
    "github.com/syntaqx/echo-middleware/gorelic"
)

func main() {
    e := echo.New()

    // Attach middleware
    gorelic.InitNewRelicAgent("YOUR_LICENSE_KEY", "YOUR_APPLICATION_NAME", true)
    e.Use(gorelic.Handler())

    e.Run(":8080")
}

Memory usage

For example from the image below, I straight away knew that handling the right to view data for user with errors, seems not to be the right way. On such a page the response time rises immediately (green and purple lines).
