The DeferPanic insights client allows you to track things such as goroutines, garbage collection, and memory usage. By default, metrics are updated every minute.

You can get started with this:

package main

import (

func makego() {
	for i := 0; i < 1000; i++ {
		go func() {
			time.Sleep(120 * time.Second)

func main() {
	dfs := deferstats.NewClient("v00L0K6CdKjE4QwX5DL1iiODxovAHUfo")
	go dfs.CaptureStats()

	go makego()

	time.Sleep(120 * time.Second)

After the first minute or so you should see activity in your dashboard. Here we can see over 1k goroutines that we created.
